What are the main functions of PLC communication module? Is it connected to the monitor?

The monitor cannot be connected to the PLC communication module. The main function of PLC wireless communication is to realize remote wireless control, remote alarm and remote maintenance of PLC configuration software. The main application fields include:

1 Used for remote wireless monitoring, remote maintenance, remote alarm, remote control and remote acquisition of PLC.

2, the temperature and humidity of the computer room, smoke, water leakage, broken glass, access control and other detection alarm.

3, remote open or close industrial equipment, such as motors, pumps, solenoid valves, etc.

4, switch back and forth, such as power failure alarm, cable security, etc.

5. Remote monitoring of dry contact signal state.

6. Remote data communication with field sensing equipment of industrial equipment.

7, street lamps, landscape lights, urban lighting wireless intelligent control.

8. Remote monitoring of water levels in water towers and high-level pools, and early warning of water levels in reservoirs, water towers and pools.

Extended data:

Functional overview:

1) supports cloud monitoring service, and computers can read and write PLC variables remotely as long as they can access the Internet. Support mobile Internet access.

2) At the same time, it supports reading and writing all the registers of PLC through SMS, and realizes SMS alarm and SMS remote control.

3) GRM200G has its own digital input and analog input, which can connect various sensors and switches to realize the function of wireless sensor.

4) If the monitored equipment fails, GRM200G will automatically send an alarm message to the mobile phone of the person on duty and display the alarm on the computer.

5) The personnel on duty can send short messages or control GRM200G on the computer to realize equipment start-stop, parameter setting and fault reset.

6) After the alarm is generated, the power supply of the equipment can be cut off through the relay output of GRM200G.

7) Equipment information can be sent to the mobile phone of the personnel on duty regularly.

8) The equipment can be controlled by telephone. One end of GRM200G can be controlled not to answer, and there is no need for cell phone calls.

9) Support the alarm of mains power failure, and send an alarm message in case of power failure.
