Direct exchange of data between multiple PLCs via GPRS for long-range wireless communication

multiple Large-control PLC wireless communication module between the direct exchange of data through GPRS, the customer does not need any network knowledge and build a server, the typical application is as follows (the GRM module below must be G-series module, and need to insert the mobile card to open GPRS):

Case 1: The remote sensor, the switching signal is passed directly to the PLC.

Case 2: Multiple PLCs Exchange data with each other.

In addition to the above example can realize the long-range wireless communication between the PLC Exchange data, but also to achieve between the touch screen and PLC, configuration software and plc between the touch screen and sensors, such as remote exchange data.

Program Features:

1. No distance limit, only a mobile phone signal can be.

2. No master-slave restriction, can achieve a one-to-many, many-to-many, many-to-more data exchange in various ways

3. Simple to use, for customers, no network knowledge, no need to build a server.

4. Good compatibility, support different types of communication protocol type PLC, touch screen, configuration software exchange data between each other

5. Scalability is good, can be added to different devices at any time.

6. The data of each device can also be viewed through the Mobile Computer Web page and configuration software.

How to complete remote monitoring:

1. Use GRM200 engineering configuration software GRMDEV3 to complete grm200g engineering development and download. Please refer to the previous section for the method of connecting the device via the communication port and the local IO.

2. grm200g when the download is complete, insert the SIM card to log in to the Cloud monitoring server. Wait for the digital tube to display "one".

3. Request a data exchange function from the giant control technology and get a username and password

4. Use your mobile Web browser or your computer's Web browser to open the Web address of the macro control cloud and enter your username and password.

5. Click "Add/Remove/Edit Device" to add the serial number of the module that needs to exchange data to the user

6. Click "Server Data Interchange Management" to enter the variable information that needs to be exchanged.

7. After the configuration is complete, the module can exchange data directly after committing the changes.

If the 2 modules can be implemented with each other data: every three seconds, if the switch volume changes, will be module number 438 variable named "Pump 1th Run Feedback" variable value assigned to the module sequence number 447 variable named "Remote run Feedback" Variable! Every three seconds, if the value of the analog change threshold exceeds 0.8, the variable named "liquid level #0.8" with the module ordinal 447 is assigned to the variable named "remote level" of the variable with module ordinal 438.
