Here is what you can find in this section:

3.1 Putting in Operation

3.2 GSM LED Indicator

3.3 Input and Output Circuits

3.4 Input Calibration

2N® TELEKOMUNIKACE a.s., www.2n.cz

19

3.1 Putting in Operation

Operational state is 2N® SmartCOM's main function. In this state, periodic data readouts from input circuits are made. 2N® SmartCOM responds to queries from the superior data concentrator, which can be the 2N® SmartCOM server, monitors the events on the RS-232 / 485 / M-Bus interfaces and sends the acquired data to the server via GPRS, or Ethernet in the case of the PRO ETH version.

Initialisation

Insert the PIN–disabled data SIM card in 2N® SmartCOM and connect the GSM antenna and power supply as instructed in Subs. 2.3., Mounting.

When the 2N® SmartCOM power supply is connected, the LED indicator on the upper side of the module flashes three times quickly and then starts flashing in longer intervals. Refer to Subs. 3.2. for LED status details. The GPRS module starts communicating with the provider in about 10 seconds trying to log in and obtain the IP address. The LED starts shining constantly to indicate a successful login.

Tip

2N® SmartCOM is working if the LED indicator is shining, thus indicating a successful mobile provider connection and IP address assignment.

To identify the 2N® SmartCOM IP address assigned by the mobile provider or perform the basic configuration upon power up, get connected via the serial port (RS 232). The port is in the data mode upon power up, retransmitting all data from the input to the GPRS network. Use the +++ sequence preceded and followed by a 1–second delay to switch into the configuration mode. When your 2N® SmartCOM replies OK, start configuring using the AT commands as listed below.

Restart the serial port to return to the data mode. To do so, you can either send the ATO command or disconnect 2N® SmartCOM from the power supply.

Tip

2N® SmartCOM can also be configured via Terminal Config. Refer to S. 6.

If you cannot use a PC, make the basic settings using SMS messages. Refer to S. 5 for details.

When your 2N® SmartCOM has been programmed as required, connect the device to the available serial ports RS-232 / 485 / M-Bus. Launch the hyperterminal and get connected to the 2N® SmartCOM public IP address via port 10000, which, together with the serial port, can be used for configuring. Use port 10001 for retransmitting data to RS-232 and port 10002 for retransmitting data to RS-485 / M-Bus.

3.3 Input and Output Circuits

This subsection describes the input and output circuits of 2N® SmartCOMincluding main use, control and location.

Tip

2N® SmartCOM is equipped with reliable terminals for easier and faster connection.

Input Circuits

2N® SmartCOM is equipped with two inputs, which are mutually galvanically connected with the GND reference point (have a common GROUND). Remember to keep the parameters specified in the Technical Parameters at the end of this manual.

The input circuits can work in three modes – voltage, current or logical levels – as configured.

Voltage measurement

Voltage can be measured in the range between 0 and 10V DC. Make sure that the 2N® SmartCOM jumpers are set as shown in Figure 3.3 before using this mode. Use the AT commands listed in Subs. 4.2 (ADC) for reading and calibration.

Current measurement

Electric current can be measured in the range between 4 and 20 mA. Make sure that the 2N® SmartCOM jumpers are set as shown in Figure 3.3 before using this mode. Use the AT commands listed in Subs. 4.2 (ADC) for reading and calibration.

Logical level monitoring

You can monitor the logical levels of voltage and current signals. Use other commands that those intended for classic measurements and define the threshold levels. Again, use the AT commands for reading values on input circuits.

Pulse counting on S0 inputs

Make sure that the jumpers are set as shown in the figure below for pulse counting on S0 inputs. The S0 input has thus a power supply of its own and can be connected directly to the switch or relay contacts. The counter is disabled by default and has to be enabled using the AT commands included in Subs. 4.2.

The figures below show the location of jumpers for current/voltage input switching. Release the screws and remove the case cover to get access to the jumpers. See the figure to the right for correct setting.

Output Circuits

2N® SmartCOM is equipped with two relay outputs for turning on/off electrical appliances (by an additional power switch, depending on their power input), or signalling, control and so on. Remember to keep the parameters specified in the Technical parameters at the end of this manual.

You can control the relay outputs with the AT commands from the CMD mode of the RS 232 interface, via a remote GPRS connection to the SIM card IP address, or using an SMS message. Refer to Subs. 4.2 for AT command details and S. 5 for SMS configuration details.

2N® TELEKOMUNIKACE a.s., www.2n.cz

23

Caution

Attention! – Any manual setting is valid until the next change or device power off. 2N® SmartCOM does not keep in mind the relay settings and restores the default status upon power up.

Set the parameter determining the relay position upon power up to 2 to make your 2N® SmartCOM remember the last contact position before power off. Refer to the configuration subsections for more details.

RS-232 and RS-485 / M–Bus Interfaces

Find the interface connectors on the bottom side of 2N® SmartCOM. Refer to Subs. 2.1. A 9-pin D-sub connector is used for RS-232 and a 6-pin RJ12 connector is used for RS-485 or M-Bus in the 2N® SmartCOM basic version. Follow the wiring instructions on the label. 2N® SmartCOM PRO and 2N® SmartCOM PRO ETH use a 3-pin WAGO terminal for bus connection located on the bottom panel next to the power supply terminals. Follow the wiring instructions on the label.

IP Access

To access 2N® SmartCOM via the IP protocol, use a Telnet supporting terminal and get connected to the 2N® SmartCOM public IP address. 2N® SmartCOM must be in mode 3 , STANDALONE, to provide access to three ports, each of which serves one interface.

Tip

Port 10000 – helps you configure, control the output relays and measure quantities on the input circuits.

Port 10001 – works as a data pipe to port RS 232 retransmitting all RS 232 events to GPRS.

Port 10002 – works as a data pipe to port RS 485 / M–Bus retransmitting all RS 485 events to GPRS.

Gel–Lead–Acid Accumulator Charger

This function is available in the 2N® SmartCOM PRO version only, which contains an intelligent charger for an external gel–lead–acid accumulator. Charging is controlled automatically and terminated when the accumulator has been completely charged. In the case of power failure, the system is fed continuously by the accumulator and, upon power recovery, the accumulator is charged automatically. A 6V or 12V accumulator can be used and charged on condition that the power voltage is 1V higher at least than the maximum voltage of the accumulator.

2N® TELEKOMUNIKACE a.s., www.2n.cz

24

Real Time Clock

This function is available in the 2N® SmartCOM PRO version only. The real time clock is backed up by a super capacitor, which keeps it running for 2 days in the event of switch–off or power failure. The clock is programmed via the configuration AT interface or from the 2N® SmartCOM Server automatically.

Wireless M–Bus Interface

This function is available in the 2N® SmartCOM PRO version only, which is equipped with an optional Wireless M-Bus interface. The WM-Bus interface parameters depend on the module used (radio frequency, e.g.). You can define up to 64 meters from which the device can collect readings. Having received a WM-Bus message from a meter defined in the meter table, 2N® SmartCOM PRO saves the message into a circular buffer in the internal memory. The saved data can be retrieved and deleted starting from the oldest record. When the memory fills up, the oldest data are deleted automatically to make space to new records. You can define the minimum reading interval for each meter. Any reading received from a meter before the end of this interval will not be stored.

The WM-Bus module can work and support encrypted messages in four modes: T1, S1, C1 and T1+C. In the basic configuration, the terminal does not decrypt messages and saves them as received. If you enter the correct encryption key and enable decryption, the received message will be decrypted and saved as a decrypted message. The encryption keys are not stored in the terminal memory for safety reasons, but written directly into the module. Therefore, if encryption fails, make sure that the device is transmitting properly, check the device settings in the terminal and re-enter the encryption key.

ZigBee Interface

This function is available in the 2N® SmartCOM PRO and 2N® SmartCOM PRO ETH versions only, which are equipped with an optional ZigBee communication module. The ZigBee interface parameters depend on the module used (radio frequency, e.g.). You can define up to 16 devices for mutual communication. The IEEE 802.15.4 – ZigBee communication technology is a member of the wireless PAN group (Personal Area Networks). Another, very popular PAN member, IEEE 802.15.1 – Bluetooth, is widely used in consumer electronics, but is not suitable for all industrial applications. This is why a new wireless communication standard, ZigBee, has been developed for industrial automation. At present, over sixty firms including world leaders in automation are involved in ZigBee development and improvement. ZigBee has been designed as a simple and flexible technology for extensive wireless networks where no large data volumes are transmitted. Reliability, simple and undemanding implementation, low power requirements and, last but not least, a good price make ZigBee a perfect solution. Like Bluetooth, ZigBee is intended for connection of low-power devices in PANs over distances of up to 75 metres. Being equipped with multi-drop ad-hoc routing, ZigBee also provides communication over longer distances without requiring direct visibility of the devices connected. It is widely used in industrial applications and sensor networks as it needs no special licence (has a general licence). Its working bands are approximately 868 MHz, 902–928 MHz and 2.4 GHz and transmisition rates amount to 20, 40, 250 kbps.

3.4 Input Calibration

A 10-bit A/D converter is connected to the IN1 and IN2 input terminals, which converts the measured value to a number ranging between 0 and 1023. Practically, the 0 - 1020 range is used; the remaining three steps are used for overvoltage detection.

The purpose of calibration is to compensate the inaccuracy of components and external factors and to ensure that the 960 value of the A/D converter matches exactly 10V in each input. The value usually oscillates slightly around this point. Let us give an example: suppose you place two terminals next to each other under identical external conditions. One terminal will measure 966 and the other 957 for 10V. Calibrate the input to eliminate such inconsistency.

Note

Keep in mind that an uncalibrated input is not non-functional. It is able to measure and read values less precisely, but sufficiently for rough voltage or current detection.

For calibration, use the terminals and AT commands described in Subs. 4.2, or the Terminal Config tool - refer to S. 6 - for setting and application details. The following figure shows the calibration diagram and basic principle. The meaning of the curves are explained below.

Figure: Calibration Diagram

The green lines indicate that no calibration has been made yet. The A/D converter

works in the whole range and deviations may occur from the actual value measured on the input. If you, in this situation, set Threshold low to 0V and Threshold high to 10V on the input, the terminal will be calibrated for 10V precisely. For 0 on the input, the AT command will return 0. For 10, we obtain 100. 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. Apply precisely one half of the calibrated voltage, i.e. 5V, to the input. The AT command will return 50, i.e. one half of the 0 - 100 range again. In this case, 5V is the centre of the calibrated range. If, however, the range was shifted, the value would be shifted too as shown below.

The yellow 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 as 70 represents 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.

If you use the calibrated input for reading logic values, keep in mind that the calibrated area is considered unstable. Values lower than the set minimum will be 0 and those exceeding the maximum will be 1. No value is guaranteed in an unstable area and a spurious state change may occur any time in the interval. Practically, the decisive level is near the middle of the set interval.

4. Configuration by Terminal

In this section we describe the 2N® SmartCOM configuration using AT commands entered into the command line.

Here is what you can find in this section:

4.1 Configuration

4.2 List of Supported AT Commands

2N® TELEKOMUNIKACE a.s., www.2n.cz

29

4.1 Configuration

The basic 2N® SmartCOM configuration and firmware download take place during the manufacturing process. In general, no additional configuration is necessary except for GPRS connection to the Internet on the GSM module and the port baud rates, which may be different depending on the providers and types of peripherals. You can configure 2N® SmartCOM in one of the following two ways.

Via the RS-232 serial interface; or

Via the IP interface.

Configuration via RS 232

The RS-232 port is always in the data mode upon power up, which means that it retransmits all captured events to GPRS port 10001. Therefore, to configure 2N® SmartCOM via the serial port, switch the port into the command mode first and then get connected to it using your PC serial port. The baud rate is 115,200 bps by default. Now enter the following sequence of characters, preceded and followed by a 1–second delay, into the terminal:

+++

When 2N® SmartCOM answers OK, you can start configuring the device using the AT commands listed in Subs. 4.2.

Restart the RS-232 port when you have finished configuring to return into the data mode. Send the following command:

at^scport1="restart"

Configuration via IP

If you know the 2N® SmartCOM public IP address, you can configure the device remotely too using the IP protocol. If not, connect to 2N® SmartCOM using RS-232 as described above and send one of the following commands (for GPRS/Ethernet):

at^sccfg="local_ip" at^sceth="local_ip"

2N® SmartCOM will send you the IP address as negotiated with the provider or assigned by the DHCP server in the Ethernet case. If a fixed public IP address is activated on the SIM card, the SIM will always use this IP address. If a dynamic public IP address is used, check the IP address whenever your restart the device.

2N® TELEKOMUNIKACE a.s., www.2n.cz

30

Caution

Make sure that the IP address assigned to the SIM card is public. It is because you will not be able to establish remote connection to 2N® SmartCOM in the STANDALONE mode if an IP address from the provider's internal range is used. The 2N® SmartCOM address need not be public if you use the TCPCLIENT server connection.

If you know the public IP address, launch the Putty and get connected via port 10000, which, together with the serial port, can also be used for configuring. Port 10000 is used for configuration, input data reading and output control in the IP domain. It is in the command mode upon power up and thus need neither be switched nor restarted after configuration.

Note

This port requires the safety password if configured so.

Caution

If your 2N® SmartCOM fails to respond to incoming TCP connections, check the status of the port to which you are connecting. If the port is in the command mode, notification on incoming connection is sent to the line (RING is displayed). Hence, enter the 'ata' command for answer or set automatic answering by parameter ats0. Refer to the

General Commands subsection in the List of supported AT commands below.

4.2 List of Supported AT Commands

This subsection describes all the AT commands that can be used for 2N® SmartCOM c onfiguration, including precise format and function specification.

2N® SmartCOM GSM Commands

These commands help configure the connection to the GPRS network.

at^sccfg="mode",2

Enter the command to set the 2N® SmartCOM operating mode. There are three options:

TCPCLIENT mode (1) - 2N® SmartCOM connects and retransmits data from its ports to the selected server.

STANDALONE mode (3) - 2N® SmartCOM works as a server to which clients get connected (transparent TCP – serial port transmission).

DATA_OFF mode - 2N® SmartCOM GSM/UMTS module does nor log in to the data network but waits for SMS.

Tip

Enter the mode number or name or select a port. The AT command then looks as follows:

at^sccfg="mode","tcpclient"

Caution

The ETH port is visible in the network in the DATA_OFF mode. PING is possible, but establishes no outgoing connection and rejects any incoming connection.
