Siemens S7200 PLC Texting application Program

Brief introduction of Siemens PLC Texting program

In order to realize unattended, in the equipment failure, by SMS or dial-up method, notify on-duty personnel, in the PLC control system has been widely used. The traditional way of implementation of the general adoption of the communication through the PLC to receive SMS Cat way, through the PLC free communication Protocol, Control plc issued text messages. The drawbacks of such schemes are:

1. Complicated procedure, need to be familiar with PLC free protocol programming, at instruction set, if need to send Chinese text message, also need Unicode encoding, very troublesome, so, use the way of SMS cat, generally only realize simple alarm.

2. Poor reliability, a lot of ordinary SMS cat is not designed for the harsh industrial environment, more use of domestic modules or demolition of the module tc35i, prone to panic, no response and so on.

New solutions:

1.plc does not need to write any program , simply simple configuration of the GRM200 module. SMS features include Chinese SMS Alarm, SMS Query plc register, SMS modification register .

2. directly supported PLCs include Mitsubishi, Siemens s7-200,s7-300,s7-400, Omron, Delta and standard Modbus master-slave protocol .

3. Can also be connected through the Modbus communication Panasonic PLC, Yonghong plc, Schneider Plc,ab plc and other plc.

4. Can be used as modbus slave and touch screen, configuration software directly connected to achieve SMS function.

5. The industry's first industrial-level SMS Alarm controller certified by the anti-jamming test.

6. The high priority alarm can be set to SMS confirmation. If the person on duty does not confirm this alarm, the alarm information will be sent to the duty personnel in accordance with the set time interval. And can first call on duty personnel mobile phone, and then send text messages.

Hardware Requirements and wiring:

The program only needs a Siemens PLC, and the giant control GRM200 module. Configure GRM200 to complete the plc text message alarm.

Connect the s7-200 PPI communication port and the GRM200 directly. The giant control GRM module supports multi-master PPI protocol, the same communication port, can also hang touch screen, do not occupy the communication port alone! The connection diagram is as follows:

For example, using the PPI Multi-master protocol, GRM200 as the No. 1th Master Station, touch screen as the main station NO. 0, a plc as the No. 2nd Slave Station. The requirement of the three baud rate is consistent.

The bus can also hang more Siemens PLC, require all Siemens PLC from the machine address different, the baud rate is consistent.

GRM200 Software configuration:

The solution only needs to configure the GRM200 module, which can be configured with USB and GRM200 connections.

(1) GRM200 use method similar to configuration software, just select the corresponding PLC communication protocol, GRM200 can actively collect PLC data.

(2) Configure the required reading of the PLC register, and the corresponding address, such as, GRM200 will actively read the s7-200 VW100 data.

(3) Configure the alarm conditions, temperature value vw100>50, SMS module to the duty personnel to send text messages.

(4) Configure Alarm SMS Content

If the alarm set issued by the text message: 2013-07-10:12:30:12 temperature is too high!

(5) Configure users to receive SMS messages

(6) Configure the mobile phone number received by SMS

Support PLC Model:

1:modbus host protocol, support letter Jie and other domestic plc.

2:modbus from the machine protocol, can connect Waylon, Siemens and other touch screen.

The 3:PPI protocol supports Siemens s7-200 PLC.

The 4:MPI protocol supports Siemens S7-300,S7-400 PLC communication.

5: Mitsubishi FX Series PLC protocol, Support FX series PLC all models.

6: Mitsubishi Q Series PLC protocol.

7: Omron hostlink protocol.

8: Delta PLC protocol.

9: can also be connected through the Modbus communication Panasonic PLC, Yonghong plc, Schneider Plc,ab plc and other plc.

With GRM200 SMS Control dunning, you can start and stop the device remotely at any time, with greater flexibility and concealment than fixed-term Dunning. At the same time, GRM200 has the ability to not be cracked or relieved by the user, can achieve a high reliable collection.

1: High reliability, cannot be relieved. GRM200 with timing, conditions, such as script, can be PLC part of the logic and GRM200 with the execution, even if the plc is cracked, can not release Dunning. The program of the GRM200 module itself can only be downloaded, cannot be uploaded, and cannot be changed after it is locked.

2: The module itself with analog and switching input and output, with the use of PLC logic, you can dispense with the PLC analog expansion module, and better achieve a confidential effect.

3: If the user unplug the communication line, can be set to the machine by the Dunning stop

4: The user unplug the antenna, can be set to the machine by the Dunning stop

5: The user takes out the SIM card, can set up the machine to be Dunning to stop

6: The user is replaced by other SIM cards, can be set to the machine was Dunning down
