Question 2

2N SmartCom PRO / Factory reset - How to make a factory reset

Accepted Answer

Factory reset - jumpers:  disconnect 2N SmartCom PRO from the power supply  loosen the screws and remove the upper part of the case    connect the jumper as shown in the figure above (Interconnect pins 3 and 5)  now reconnect the power supply. Upon power up, the Flash memory is deleted and the factory default values are reset for all ports    remember to remove the jumper to avoid deletion of the settings upon every start!        Factory reset - AT command:     at^scfres    following command make the software factory reset. The command only sets the default parameters without deleting the Flash and EEPROM data memories.          Factory reset - SMS:     SC FRES PWD=  send SMS to initiate the terminal factory reset.  you will get a response SMS - "Factory Reset Initialized" and the command will be executed

Question 3

2N SmartCom PRO - Input circuits

Accepted Answer

2N SmartCom PRO is equipped with three inputs, which are mutually galvanically connected with the GND reference point (have a common GROUND). The input circuits can work in three modes – voltage, current or logical levels – as configured.  disconnect 2N SmartCom PRO from the power supply before opening the cover  loosen the screws and open the box lid to get access to the PCB jumpers.  The figures below show the location of the current/voltage/S0 switching jumpers:    Note: If you want to use voltage mode and current mode properly, you need to calibrate 10-bits A/D converter connected to the input terminals (IN1, IN2, IN3). But keep in mind that an uncalibrated input is still functional (but can read values less precisely).    Voltage Measurement Voltage can be measured in the range between 0 and 10 V DC. Make sure that the 2N SmartCom PRO jumpers are set as shown in the figure above before using this mode.   Current Measurement Electric current can be measured in the range between 4 and 20 mA. Make sure that the 2N SmartCom PRO jumpers are set as shown in the figure above before using this mode   An example is given for the ADC circuit 1 (scadc1). To read circuit 2(3), replace 1 with 2(3) in the command (scadc2/scdc3). at^scadc1="get_value"  The command performs measurement on the selected interface and sends the calibrated value measured.  at^scadc1="adc_value"  The command performs measurement and returns the value from the A/D converter.  at^scadc1="calib_min"  Automatic interface calibration according to the currently measured value.  at^scadc1="calib_max"  Automatic interface calibration according to the currently measured value.  at^scadc1="threshold_low",1200  Manual calibration setting (minimum values). Setting options: 0–4090.  at^scadc1="threshold_high",3250  Manual calibration setting (maximum values). Setting options: 0–4090.  at^scadc1="save"  The command saves the changes.    Logical Level Monitoring You can monitor the logical levels of voltage and current signals. Use other commands than those intended for classic measurements and define the threshold levels. Again, use the AT commands for reading values on input circuits. at^scdin1="get_value"  The command detects the logical level on the selected interface and sends the value 1/0  at^scdin1="calib_min"  Automatic interface calibration according to the currently measured value  at^scdin1="calib_max"  Automatic interface calibration according to the currently measured value  at^scdin1="threshold_low",1400  Manual calibration setting (minimum values). Setting options: 0–4090  at^scdin1="threshold_high",3450  Manual calibration setting (maximum values). Setting options: 0–4090  at^scdin1="save"  The command saves the changes.

Question 4

2N SmartCom PRO M-Bus overview

Accepted Answer

2N SmartCom PRO can be equipped with M-Bus interface and can collect data from up to 5 M-Bus devices (with extender it can be up to 250 M-Bus devices). This website describe possible scenarios and some examples how to collect and use M-Bus messages with 2N SmartCom PRO. 2N SmartCom PRO can be configured via hyperterminal software or 2N SmartCom Terminal Config software. The SmartCom terminal can be set to a Standalone mode unit or TCP Client mode unit connected to 2N SmartCom Server.In TCP client mode terminals are connected to the server and you can very easily manage them via 2N SmartCom Control Panel software.  End device (water meter, electricity meter, heat meter etc…) To be able connect the end device to 2N SmartCom PRO terminal you need to know at least M-Bus setting of the end device (can be in meter´s manual):  Primary address  Speed [bd/s]  Data bits  Stop bits  Parity    2N SmartCom PRO M-Bus settings You need to set all M-Bus parameters in 2N SmartCom PRO. You can do the settings using SmartCom Terminal Config Software or via at commands using serial / telnet terminal software. Settings M-Bus: speed 2400bd/s - data bits 8 – stop bits 1 – parity – none at^scport2="baudrate",2400 Set Baudrate at^scport2="DATA_BITS",8 Set data bits at^scport2="STOP_BITS",1 Set stop bits at^scport2="PARITY",0 Set parity at^scport2? Check settings at^scport2="save" Save settings         M-Bus data readout from 2NSmartCom PRO Data can be read using 2N  SmartCom PRO in two modes either Transparent mode or using Autonomous Metering System functionality:  Transparent mode:  2N® SmartCom PRO is used as communication data channel and data are not stored in 2N® SmartCom PRO internal memory. Application / script, reading M-Bus data from meter is running on remote server site and reading data using 2N® SmartCom PRO communication interface. Data are stored on server site in the application or file. There are no data available in case the 2N® SmartCom PRO is not available over IP network  Autonomous Metering System (AMS)  With AMS functionality 2N SmartCom PRO can read and store M-Bus data from meter autonomously in predefined interval. Read data are stored to internal memory of 2N SmartCom PRO. Data are stored in original M-Bus format. Data are presented in the 2n® SmartCom PRO internal memory even when the WAN connection is not available. So you can easily read them out from the memory when connected to the terminal (no matter whether it is local RS232 or telnet connection). It can prevent missing data in case the IP network is not available.   M-Bus messages and parsing  Original M-Bus format: You can work with M-Bus messages in original format defined by M-Bus standard. All types of M-Bus messages are described for example on website http://www.m-bus.com/, messages are in HEX format. You can request the data from meter by sending commands to M-Bus meter directly through the SmartCom PRO terminal for example from hyperterminal or some software which support HEX strings. In Standalone mode you need to use telnet for SmartCom PRO terminal communication (IP address of 2N ® SmartCom PRO and port 10002).In TCP Client mode you can create and use virtual port (serial or TCP port), that virtual port can be mapped to 2N ® SmartCom PRO M-Bus interface.    Autonomous Metering System (AMS)  2N SmartCOM PRO can be set to reads data from M-Bus end device autonomously and store data in internal memory. Format of stored M-Bus message in internal memory: ^SCDATA:,,,,,,,  - typ of record - AMS  - time mark  - sequential number of saved record  - name of protocol  - index of device from table of devices  - number 0 = without error  - not used in M-Bus  - raw data Raw data: at^scdata="get_oldest",3 ^SCDATA: "AMS",1427985840,25036,"MBUS",1,0,"","685E5E6808007268170308653299068E0000000C13911800000B22730404046D3510E2 14326C00000C786817030806FD0C0A000100FA010DFD0B05313248465701FD0E004C1374180000426CDF1C0F37FD170000000000000000027A2500027825004116"    Script that runs on you Server / PC:  You can create your own script for parsing M-Bus messages. Examples of testing scripts are available on request from 2N support. Those scripts are based on linux library libmbus (http://www.rscada.se/libmbus/). Data are processed and saved to TXT, CSV, and similar files format. Examples:  Data from water meter Siemens parsed by libmbus library      8031768 LSE 153 Siemens WFH21 Hot water 13 00 0000     Instantaneous value Volume (m m^3) 1913 2015-06-22T13:49:42     Instantaneous value On time (hours) 42417 2015-06-22T13:49:42    ....

Traffic grapher is not included in 2N® SmartCOM PRO or 2N® SmartCOM Server. You can use you preferred tool.     M-Bus monitoring software  You can use M-Bus monitoring software which will analyze and display data from 2N® SmartCom PRO. Example: You can create your account in Energy monitoring cloud service Smart – me (http://smart-me.com). How this example works:  Via 2N® SmartCom PRO read M-Bus data.  2N® SmartCom Server processed data using additional script which sends the final data format requested from Smart-me to your account at Cloud service Smart – me  You can display results online

Question 5

2N SmartCom PRO  - Terminal error buffer code description

Accepted Answer

An error buffer is implemented in each terminal to store data on terminal operation errors. To display the buffer contents use either the terminal (an AT command) or an SMS.  SMS: The SMS displays the last 10 errors starting with the most recent one. SC ERR PWD= [CLR] This command includes one optional parameter – CLR. If you add this string after the password in the command SMS, you will receive an SMS showing the current buffer contents and all errors will then be deleted from the terminal memory. The following reply will come from the terminal after processing:1:8,10 2:3,10 1:1,0 7:8,10 6:8,7 5:7,40 4:11,848   AT COMMAND: Error codes are obtained by AT^SCERR? which response is: ^SCERR: {id}> {ID}, {Additional value}id - Sequence number of the error since the last start-up.ID - Error identification.

Question 10

Difference between Standalone and TCP Client mode in 2N SmartCOM (PRO)

Accepted Answer

2N SmartCOM (PRO) terminal can be used and configured in two different modes – the first one is "Standalone" mode and the second one is "TCP client" mode. It is important to know when these modes can be used, what the differences between them are and how you can configure them. The main idea of Standalone mode is that 2N SmartCOM works as a server to which clients get connected (transparent TCP – serial port transmission). In TCP client mode 2N SmartCOM connects and retransmits data from its ports to selected server.  Standalone mode Before you start to set the unit to Standalone mode you can just type a command mentioned below this paragraph to double check currently set interface values. The output looks like the one in the next picture. at^sccfg? After that if you need to change a mode in your unit to Standalone, enter one of following AT commands (use serial connection to the terminal via RS-232 cable or Telnet connection via Putty): at^sccfg="mode","standalone" or at^sccfg="mode",3    Then if your unit is in the standalone mode and has been already installed somewhere on remote side it is very useful to access it via IP protocol (for further configuration, relays control, inputs measuring, etc.). In this case it is recommended to use a program (such as Putty or Hyperterminal) which supports Telnet connection to specific IP address and port. Public IP address has to be assigned to your 2N® SmartCOM unit. Once this condition is met you can access three ports which serve different interfaces and have different use:  Port 10000 – thanks to this port you can configure the unit, control the output relays and measure quantities on the input circuits.  Port 10001 – this port works as a data pipe to port RS-232 and retransmits all RS-232 events to GPRS.  Port 10002 – this port is very similar to previous one and works as a data pipe to port RS-485 or M-Bus (depends on the type of unit you have). This port retransmits all RS 485 events to GPRS.  Note: You can also use our program called Smc Terminal Config Program for configuration which is available on our web for free.       TCP client mode 2N SmartCOM in TCP client mode needs to be always connected to 2N SmartCOM Server which collects data from terminal unit and can send them to some 3rd party application via API interface (it is good if you want e.g. graphical outputs from read out units). Once you want to set your terminal to TCP client mode then you have to enter one of two following commands: at^sccfg="mode","tcpclient" or at^sccfg="mode",1   After that you have to specify several other parameters which are necessary for successful interconnection between terminal unit and 2N SmartCOM Server. All these parameters and appropriate commands are described in User Manual (the link below) but the most important commands are also described in this FAQ. 4.2 List of Supported AT Commands a) Set the APN to your mobile provider (for data connection) – there is configuration for O2 CZ in the example: at^sccfg="gprs_apn","internet.open"   b) Set username and password for authentication by the provider (if it is required). Most providers don´t use the authentication. at^sccfg="gprs_user","internet" at^sccfg="gprs_pass","12sfd3"   c) Set the IP address of 2N SmartCOM Server to which the unit will be connected. It should be public IP address. Then specify also a server port to which the unit should be connected. Finally specify authorisation password for this server connection. at^sccfg="server_ip","90.182.112.54" at^sccfg="server_port","1561" at^sccfg="auth_pass","ds654fv1"   All other parameters and commands such as encryption mode settings for unit – Server communication, PIN settings, etc. are described in the User manual (the link is above).    In TCP client mode are terminal units connected to the server and you can very easily manage them via 2N SmartCOM Control Panel tool. For further information about Control Panel and also about Server read our User Manual: Control Panel 2N SmartCOM Server can also help you with FW upgrade for terminal units because it can be done automatically via server. You will just upload the appropriate FW version into a server and then select terminals to which you want to upload this FW. Next you can run e.g. different scripts on the server to read out specified values from terminals.

Question 11

Ethernet port - 2N SmartCom PRO ETH configuration

Accepted Answer

1. In the very first step you should read the manual, which you can find on 2N Telecommunications website 2. Connect 2N SmartCom PRO ETH version (next just SmC+ETH) via RS232 cable and open 2N SmartCom configuration tool. In case you are using RS232/USB converter you need to use appropriate virtual COM port on your PC. The correct number of this virtual COM port can be found in "Device manager" in your operating system. Default communication Speed is set to 115200bd/s. Once you change speed of RS232, then you will need to "Load configuration" with that speed, see (Pic. 1). Keep in mind all parameters, in enclosed pictures there are only examples.  Pic. 1 3. To configure Ethernet port, go to tab "Ethernet", where you will do all the settings. LED diode has got two modes. Which mode will be used depends on switching "LED signalization" parameter. LED diode is placed close to SIM holder. Now you need to decide whether the SmC+ETH will obtain IP address from DHCP server or set the static IP address, see (Pic. 2).  Pic. 2 4. You have to "Save and restart" the device in order to apply changes in IP settings, (Pic. 3), when LED diode starts shining, the SmartCom is ready to be used again! You can "Load configuration" because of verifying IP address from DHCP server (Pic. 4).  Pic. 3  Pic. 4 5. Once you know SmC+ETH unit IP address, you can do any reconfiguration remotely via telnet client. Putty client is used in this example. To reach the configuration mode of the unit set IP address and port 10000, see (Pic. 5).  Pic. 5 6. AT command at^sceth? enables you to display current setting and at^sceth=? will show you all the options you can use as you can see on (Pic. 6). On (Pic. 7) you have whole list of supported AT commands which are listed in the manual, section 9.2.  Pic. 6  Pic. 7

To review the port settings enter at^scport1=?

Question 14

How to configure Wireless M-Bus port

Accepted Answer

In order to configure WM-Bus port just run Putty or Hyper terminal software, connect to SmartCom and enter the listed commands. 1) First of all check the configuration of 2N SmartCom: at^scwmbus?  Make sure that you have configured correct mode (it must be the same like in WM-Bus equipment) The correct mode can be set by at^scwmbus="mode",11 where “11” is mode type. SmartCom supports the following modes:  1 - T1  3- S1  8- C1  11- T1+C  17 - N1  2) Discover required equipment at^scwmbus="sniff" Wait a little unless SmartCom discovers available WM-Bus equipment    3) Add discovered equipment to SmartCom at^scwmbus="dev_add", "VIP",81424136,0,01,07  4) Some WM-Bus equipment send encrypted messages. These messages must be decrypted by SmartCom to provide the readable data. In this case enable decrypting by parameter "1" in the following command (0 disables decryption mode) at^scwmbus="decrypt",1   Each vendor uses unique decryption key, this key must be stored in SmartCom for messages decrypting:   at^scwmbus="key_add",1,A5B95C144134DE257AF2ED4F384C7EB7 where „1“ is the number of added equipment, A5B95C144134DE257AF2ED4F384C7EB7 is unique decryption code (provided by vendor). The number of added meter device can be found by entereing the at^scwmbus?.  5) If you need to delete some meter device from the table just enter    at^scwmbus="dev_remove",1 where “1” is position number of the meter in the table Or delete the whole table    at^scwmbus="dev_clear"

Question 15

How to configure Wireless M-Bus port on 2N SmartCom PRO with fw 1.13.x and latest

Accepted Answer

2N SmartCom PRO unit can be equipped up to two Wireless M-Bus modules. The 868 MHz WM-Bus module can work in four modes: T1, S1, C1 and T1+C. The 169 MHz module works in the N mode and the 433 MHz module in the T1 and C1 modes.   First of all check configuration of 2N SmartCom PRO unit: at^scwmbfilter?  The command displays the currently set meter list   at^scwmbus1?  The command displays the currently set interface (wmbus1) values   at^scwmbus1="mode",11  The command sets the operational mode for the device  1 – T13 – S18 – C111 – T1+C17 – N1 Make sure, that you have configured correct mode (it must be the same like in Wireless M-Bus equipment)   at^scwmbfilter="sniff"  The command switches the Wireless M-Bus module to the sniff mode, which captures all messages from the devices in the surroundings and displays them via the console (Press ENTER to stop capturing)     Add discovered equipment to 2N SmartCom PRO unit (you can add up to 1000 meters to the filter) at^scwmbfilter="dev_add","MAN",12345678,01,37,600  This command adds a meter to the meter list. MAN is a three-letter abbreviation of the manufacturer followed by the meter serial number. The following two parameters are also necessary for meter identification: Version and Device. Ask the device manufacturer for these values. Or intercept them using the sniffer, see below. The next parameter is the minimum interval in seconds between two readings of the meter to be added. If 0 is set, all messages received from the meter are stored.   at^scwmbfilter="enable",1  The command activates/deactivates a filter. All Wireless M-Bus packets are received and saved if the function is disabled.    Check meter list by command at^scwmbfilter?    at^scwmbfilter="dev_remove",1  The command removes a meter from the list  at^scwmbfilter="dev_clear"  The command clears the whole meter list    Save your configuration at^scwmbfilter="save"  The command saves the currently set values    Decryption configuration All Wireless M-Bus modules support encrypted messages too in all the modes. In the basic configuration, the terminal does not decrypt messages and stores them as they are received. Enter the correct encryption key and enable decryption to make the messages be decrypted by the module and stored in the decrypted format in the terminal memory. For security reasons, encryption keys are not stored in the memory, but written directly into the module. Therefore, if decryption does not work, check the device transmission and device settings in the terminal and re-enter the encryption key.   at^scwmbfilter="key_add",1,A5B95C144134DE257AF2ED4F384C7EB7  The command sets the encryption key for meter 1 in the 32 HEX format (each of the meters can have a key of its own).  at^scwmbfilter="key_remove",1  The command deletes the encryption key for meter 1  The number of added meter device can be found by entering at^scwmbfilter?

Question 21

How to connect ZigBee device to 2N SmartCOM PRO (ETH)?

Accepted Answer

If you want to interconnect any ZigBee device with 2N SmartCOM PRO (or 2N SmartCOM PRO ETH) then please double check that your 2N SmartCOM is equipped by ZigBee module! Next keep in mind that 2N SmartCOM PRO (ETH) device supports selected clusters from ZigBee HomeAutomation, so it is strongly recommended to verify which clusters are supported by ZigBee device and check the support of such a device with 2N technical support. Once you checked that you can define up to 16 ZigBee devices which will be saved in the database and 2N SmartCOM PRO can communicate with them. Each device is presented by his own IEEE address (very similar to MAC address of IP devices) which consists of 16 characters – example can be 00:15:bc:00:1d:00:0e:c5.  How to configure 2N® SmartCOM? In this FAQ will be two ZigBee devices interconnected with 2N SmartCOM – the first device is a humidity and temperature meter (STH-03ZB) and the second one is ZigBee remote controlled plug with electricity meter (ZR-PLUG-FR-M). Thanks to this second device you can remotely switch on and switch off the device and also remotely measure the instant active power and the energy spent.  As a very first step you have to connect to 2N SmartCOM via RS-232 serial interface or if you know the public IP address of SIM card then you can configure the device also remotely using the IP protocol (connection via Telnet). After successful connection you can verify if some devices have already been added to the database. Type the command mentioned below to the terminal window. The output of this command is visible in the next picture where you can check that the database is empty. at^sczb?    Now you can add new ZigBee devices to the database. The only thing you need to know is the IEEE address of ZigBee device you want to interconnect with 2N SmartCOM. To add new ZigBee device enter the command shown below: at^sczb="add",00124b00029b15e0     ZigBee device with IEEE address 00:12:4b:00:02:9b:15:e0 was added to the first vacant place in the table (database). Next you can add another device to the database and finally you can check again all added ZigBee devices including their attributes, states and options.     As you can see in the picture above there are different states which can occur. Description is below:  ONLINE  – ZigBee device with specific IEEE address was added into the database and also successfully paired with 2N SmartCOM  OFFLINE  - ZigBee device with specific IEEE address was added into the database, it was also successfully paired with 2N SmartCOM sometimes before but right now it is not paired (datas aren´t read out)  CONFIGURED  - ZigBee device with specific IEEE address was added into the database, but it still hasn´t been paired with 2N SmartCOM  ENUMERATING  - ZigBee device with specific IEEE address was added into the database and is trying to pair with 2N SmartCOM right now     Note: very important command is the one which shows you all supported parameters (commands) that can be used for configuration of ZigBee devices. It is: at^sczb=?

Question 27

Input circuit - 2N SmartCom/2N SmartCom PRO calibration

Accepted Answer

2N SmartCOM and 2N SmartCOM PRO terminals are equipped with two inputs which have a common ground (GND). These input circuits can work in three different modes based on the jumper settings – voltage, current or logical levels. The picture below shows the location of jumpers for input switching. For more details you can check user manual for 2N SmartCOM (PRO) – the link is below:   Note: Voltage mode and current mode will be discussed more deeply in this FAQ because if you want to use them properly then you need to calibrate 10-bits A/D converter connected to the input terminals (IN1 and IN2). But keep in mind that an uncalibrated input is still functional (but can read values less precisely).   Input calibration The purpose of calibration is to compensate the inaccuracy of components and external factors. It is a reason why you can´t guarantee that the 960 value of the A/D converter matches exactly 10V in each input. The value usually oscillates slightly around this point. Therefore it is recommended to use 10-bits A/D converter that converts the measured value to a number ranging between 0 and 1023. If you want to calibrate inputs then you have to connect to 2N SmartCOM (PRO) via e.g. Putty and use appropriate AT commands which are described below. Before we start with the configuration via AT commands let´s take a look on an illustrated diagram where is explained how calibration works and how you can use it.   You can see several different lines in the diagram above and each of them have different meaning. Let´s start with the  green  one which indicates that no calibration has been made. The A/D converter works in the whole range and deviations may occur from the actual value measured on the input. Now we can set threshold low to 0V and threshold high to 10V on the input and the terminal will be precisely calibrated for 10V. For 0 on the input, the appropriate AT command (mentioned below) will return 0 value. For 10, we obtain 100 from AT command. Thus, the calibrated input can be considered 0 - 100% of the calibrated range. The  red  lines mean that the input has been calibrated to the interval of 3 to 8V, i.e. to the range of 5V. This range now represents new measurement limits. If you apply 3V or less on the input, you are in the calibrated min area and the AT command will return 0. If you apply 8V or more, you are in the calibrated max area and the AT command will return 100. This means that the measured range width has narrowed by 50% and 0 - 100% is now mapped to the input range of 3 - 8V. The  blue  line is an example of measuring in the calibrated range of 0 to 10V. Once you apply 5V to the input (one half of the calibrated voltage) then AT command will return 50, i.e. one half of the 0 - 100 range again. However if the range was shifted, the value would be shifted too as presented by a   yellow   line. This line shows the case that 7V is applied to the input. In case you measure 7V in the calibrated 10V range, the AT command will return 70 because it is 70% of the calibrated range. But if the range is just 3 to 8V as in the red case, 7V will represent 80% of the calibrated range of 5V and the AT command will return 80.     How to configure 2N SmartCOM (PRO)?  In the very first step (before connecting of load to input circuits) it is necessary to do a calibration of input circuits.  Set the threshold low value – input circuits has to be shorted and then you have to enter to the command line an AT command for automatic port calibration at^scadc1="calib_min". If you want to set minimum value manually then you have to enter following AT command: at^scadc1="threshold_low",x (where X can be a value from 0 – 960)  Set the threshold high value – you have to add the load to the maximum threshold line which should not exceed 10V and set to the command line an AT command for automatic port calibration at^scadc1="calib_max". If you want to set maximum value manually then you have to enter following AT command: at^scadc1="threshold_high",x (where X can be again a value from 0 – 960)  In the last step you have to save calibration by the command: AT^scadc1="save".  Once you set it and do calibration you can check actual values – use the command at^scadc2?  All commands mentioned above are also used in the next picture for better illustration and you can read more about them in the user manual – the link is below:      Finally you can repeat steps above for input 2 (IN2) – you will have to replace command at^scadc1 for at^scadc2. Don´t forget to save the configuration!    Practical usage of the calibration can be e.g. for temperature measurement. If you have thermometer where the temperature is directly proportional to the voltage then you can very easily read out measured values of voltage and trigger some action. Based on these values you are able to decide if you need to cool a room (run fans), if the temperature is in the correct range (fans are off) or if you need to heat the room. The calibration can be done for specific temperature range corresponding to the voltage (let´s say that 28°C = 8V and 10,5°C = 3V). Now you can set that for measured values in the range of 80-100% (24,5°C – 28°C) you need to run a fan or air conditioning. For 40-80% (17,5°C – 24,5°C) are fans off and you don´t need to heat. Finally for 0-40% (10,5 – 17,5°C) you will have to heat in your house. In this case you will have to set threshold high to 8V and threshold low to 3V. Next actions such as relay activation for heating or air conditioning can be triggered based on the actual input value and can be configured such as User Defined Functions (UDF). More information about UDF are available in the manual and next FAQ – links are below:   User Defined Functions (UDF) - what is it and how to configure it in 2N® SmartCOM?

Question 36

User Defined Functions (UDF) - what is it and how to configure it in 2N SmartCOM?

Accepted Answer

User defined functions (UDF) provides a user–defined set of conditions for 2NSmartCOM terminal that will trigger the set of actions. These conditions must be met to make it possible to send SMS and TCP messages or to set the relay to appropriate position on the given terminal. You can define up to 10 UDF conditions for one 2N SmartCOM terminal. Each condition is evaluated continuously and if it is met (True value) then defined action will be executed. For re-execution, the condition can´t be met (False status) or remain in the set status for a timer-defined period. That´s the reason why SMS will not be sent at every iteration.  How to configure 2N® SmartCOM? First of all you have to connect to 2N SmartCOM via RS-232 serial interface or if you know the public IP address of SIM card then you can configure the device also remotely using the IP protocol (connection via Telnet). Then for the configuration of some conditions and actions in the terminal you have to use specific AT commands. Each AT command must include the condition syntax (sign) ended by the separator “:” and followed by action which will be executed (action type and action parameters). The maximum length of AT command is 80 characters. Typical example of AT command can look as follows: at^scudf="ADD","AIN1>=10:SMS P[+420777234567]m[alarm message] t[60]"   The UDF can work with the following parameters:      The following operators can be used for evaluation:      Note: more details about existing parameters, operators, values and syntax are available in configuration manual for 2N SmartCOM – the link is below: https://wiki.2n.com/faqot/en/2n-smartcom-2n-smartcom-pro-basic-configuration-104860654.html   Configuration examples Before we start with some specific configuration you can check if some UDF has already been added into the terminal. If you want to do that then you have to type the command below. This command and appropriate output is shown in next picture. at^scudf?    You can see two more AT commands in the picture above which are used once you need to remove the existing condition with selected ID from the terminal memory or to clear complete memory. at^scudf=”remove”,1 ... delete the condition with ID=1 (first row in the table) at^scudf=”clear” ... delete complete memory   Note: important command is the one which displays supported settings options: at^scudf=?   Example #1 Let´s imagine that you have 2N SmartCOM COM terminal which is supplied from standard power adapter (5-50V). Next to that you have also connected there a gel–lead–acid accumulator as a power supply backup. This will ensure that once the terminal loose the power, it is still powered from backup power supply for a while and this power lost can be detected on a specific input (you will use analog input where you can have 0V – 10V). You can be informed about that via SMS. In this example you will monitor the analog input 1 and once the value on this input is lower than 3 (depends on the calibration of A/D converter - check next FAQ on the link below) and it is detected for 300sec then SMS message is sent to GSM number +420777234567.      Example #2 In this example will be described situation when you need to be informed about the situation which occurred repeatedly – five times in this scenario. It can be exceeding of limit value on the second analog input. Let´s set this value to 50 (you can specify different value – it depends on the settings of A/D convertor) and if the current value is higher than this constant then the counter CNT1 increase its value by one. Once this situation occurred five-times the SMS message is sent to your GSM number. In the incoming message you will see also how many times the value was exceeded (total number counted in CNT2). Finally you have to reset the counter CNT1 to the default state (set 0 value). All commands are shown in the picture below.
