• If the data line used has a static IP address, the APN number that can be learned from the GSM operator must be entered correctly. For example, if the APN address of the GSM operator is 'mgbs', then the AT+GPRSAPN command is typed as 'mgbs' and the write button is pressed.
• To read the quality of the GSM line, press the read button on the AT + CSQ command line. In the example, the CSQ value is read as between 16 and 20. This value indicates that there is enough attraction power to make the connection.
• After starting the GSM line, AT+CONNECTION=? command is sent. If the command reply is '6', GPRS IP is received. AT+GPRSIP=? command is sent to find out the IP address, the device is connected.

• The PLC configured as MODBUS Master will read a register value from the PLC configured as MODBUS Slave. In MODBUS protocol a SLAVE device creates a "TCP Server Socket", however the MASTER device creates "TCP Client Socket". The MASTER device connects the SLAVE device. So the MASTER should know about the IP and PORT information of the SLAVE device.

Diagram Solution

• Two devices and two separate diagrams are used as server and client.
• GSM is selected as the media type in the TCP Socket Block.
• Modbus TCP slave block is used in server diagram. This allows the client device to connect to the server. By specifying the ID, more than one device will be able to operate as a slave. In the TCP socket block, the server is selected and the listening port is entered.
• The MODBUS TCP MASTER block is added on the client diagram to connect to the SLAVE device. Each time the rising edge of the MODBUS word reader block arrives at the trigger input, the specified register is read from the device it is connected to. The ID of the device identified as a slave should be written in the "ID" definition field in the MODBUS word reader block.
• Since the MODBUS register address of Word Register Block with modbus adress is 4000, MODBUS address is set to 4000 in to Modbus Word Reader Block. In the TCP socket of the client device, the IP number of the PLC to be connected and the listening port values are entered. The SLAVE device's IP and listening port values can be learned on the Mikroteminal application console with GPRSIP and LISTENPORT commands.
• You also need to check APN, CSQ and GPRSIP values on Mikroterminal. Please see MODBUS TCP GSM Communication example for connection settings.

Diagram Solution

• For the slave device, the Modbus RTU slave block located on the Modbus blocks tab is added.
• Serial Port Block is added for serial communication and communication parameters are set. The slave and master devices must have the same baud rate, data bit and parity option.
• The monitoring screen above is the RTU slave device, and below is the screenshot of RTU Master device.
• For the master device, the Modbus RTU master block located on the Modbus blocks tab is added.
• Since the Modbus table block reads every rising edge, the trigger is sent via the symmetric pulse generator.
• Two modbus table blocks have been used since two different register formats like Word and Analog. Because the word registers start at 4000 and the analog registers at 6000.
• The RTU master line tag has been added to the Mas input of Modbus table blocks.
• The symmetric pulse generator is connected Trg input of Modbus table blocks for trigger.
• For to be read Word and Analog values is added two separate Table Block. The output of table block is connected to the Tab input of the Modbus table block.
• The word table field must be created twice the size of the word register to be read.
• The analog values read from the Modbus table block constitute twice the number of registers read from the RTU Slave. An analog table size is created twice as much as the number entered in the Modbus table block. For example; There are 10 analog registers in RTU Slave. The number of registers in the modbus table read by RTU Master is 20. An analog table block with a table size of 40 is also added for data transfer.
• Modbus table reading function as "0x03 Read Holding Register" must be selected.
• Select "Read Offset" from the operation blocks and the table index number is entered.
• 10 Analog and 10 Word table operation blocks have been added to receive 10 data from Modbus table blocks. This method can also be used by adding two table operation block(for analog and word) and changing the offset value by connecting the register to the "inB" input of the table transaction blocks.

• In the system read with the temperature value RTD0 temperature input, it is desired to control the temperature by the fan connected to the analog output.

• PT100 sensor is connected to RTD0 input. Temperature measurement is made between -50 and 100 degrees centigrade.

• As the ambient temperature increases, the speed of the fan connected to analog output 0 will also increase.

• Ortamın sıcaklığı arttıkça analog çıkış 0'a bağlı olan fan motor hızı da artacaktır. The analog output produces current between 4 and 20 mA. As the motor speed increases, hot air will flow out. This will prevent the heating of the environment.

• PID parameters will be calculated with autotunning.

• In case of emergency, digital input signal information is received. The analog output value will be reset(4 mA) when a high level signal is input to the digital input 0.

Diagram Solution

• It is predicted that the temperature of the system will be 60 milliseconds.
• The system is run in 'autotunning' mode to set the PID parameters with Autotunning. PID parameters calculated by opening the port from the Mikroterminal console are expected to be displayed. Calculation of PID parameters is provided for 30 minutes by testing the system for possible conditions. The calculation time varies according to the system conditions.
• Once the PID parameters have been calculated, double clicking on the PID block switches the mode option to 'automatic' mode. In automatic mode, the system will continue to operate according to the previously calculated PID parameters.
• An analog multiplexer is used to reset the analog output in emergency situations. If the emergency button is not pressed (DI0), the analog value from the I1 channel of the multiplexer will be transferred to the analog output. When DI0 button is pressed, 4 mA value coming from I2 channel of the multiplexer will be transferred to analog output.

Getting Device Serial Number

You can get the serial number of the device using a "Long Math" block.

The serial number is kept in a special register with address "30000". To be able to access that register you need to use "Get" math operator in "Long Math" block. The following image shows the necessary configuration.

Updating Phone Numbers on Mikrodev Device through SCADA

By using Mikrodev devices, you can send and receive SMS messages(with non-pp* firmwares). The content of the messages and phone numbers are stored in string registers of PLC device. And these strings are configured in PLC project on "string tables".

Sometimes you may want to view and update the phone number for SMS messages through your SCADA system. The following example illustrates how you can achieve this.

Storing the Phone Number

Since industrial protocols like Modbus only supports numeric data types, you need to store a numeric version of your phone number. And since a single "Long register" is not enough for storing a phone number, this can be done by using "2 Long Registers". You can divide the phone number into 2 parts and write and read these numbers through these registers. But of course; you will also need to convert these "2 Long Registers" containing the phone number parts into a single "String Register". And copy that register into the "phone number input" of SMS block.

In the "StringManipulation Block" you need to select "ToString" function and write it into a string register, i.e "index 2".

Formatting the Phone Number

In our example; we are using 10th and 11th String indexes as the format input of the phone number parts:

You should take care of these formats and actual phone number parts. They should be in accordance with each other. That means;

If your phone number is like: +905556008899, your configuration will be something like that:

Content of 10th string index: "+90%04s"

Here"%04s" means prepend leading zeros up to 4 digits to your number.

Content of 11th string index: "%06s"

Here"%06s" means prepend leading zeros up to 6 digits to your number.

So if your first long register contains "5556" and second long register contains "8899" these numbers will merged into "+905556008899" by using these formatting rules.

In the "StringManipulation" block below, you should select "Append" operation and copy the result into a string register i.e "index 1"

Running the Logic

After configuring your "phone number string" mechanism, you just need to connect that string into the SMS block and write "1" into the "trigger" register.

View and Update on SCADA

On the SCADA side; you can display "2 Long Registers" in two different components and an apply button for triggering the "trigger" register int the PLC project. The only drawback here is that the user should use the same number of characters as indicated in the format strings in PLC project.
