PLC SMS alarm controller

product overview

Adopting Siemens' original industrial grade SMS module, designed strictly according to industrial standards, it directly supports various PLCs, and can achieve PLC SMS control, SMS alarm, SMS query, remote payment collection, etc. with simple configuration. At the same time, it can be used independently as an alarm host, generating alarms and linked outputs based on the built-in switch and analog inputs of the machine.

PLC can achieve mobile SMS function without modifying the program, AT instruction set and communication port programming.

The GRM200 intelligent SMS alarm controller is a GSM remote measurement and control terminal with PLC and RTU functions. It uses GSM (GRM200 requires inserting a SIM card into the phone) as the communication method, and has industrial grade anti-interference performance. It can be directly installed in electrical cabinets containing high-power devices and is suitable for use in harsh electromagnetic environments.
GRM200 comes with a communication port that directly supports multiple PLC communication protocols. It can be connected to Siemens, Mitsubishi, Omron PLC or MODBUS devices, as well as various touch screens and frequency converters. PLC can achieve remote control, alarm, maintenance, and payment collection through SMS without any additional programming or concern for the principles of SMS sending.
The GRM200 system adopts a configuration configuration form, supports various expression alarms, timing control, logic control, and has flexible programming functions for PLC. Using GRM200 wireless control eliminates the need for communication cables and on-site personnel, reducing system construction and maintenance costs.

Function Overview:

1) After GRM200 is connected to PLC via RS485, it can achieve SMS reading and writing of PLC registers on mobile phones.
2) The controller comes with digital and analog inputs, which can be connected to various sensors and switches. It can be used as an extension module for PLC to reduce system costs.
3) If the monitored PLC malfunctions, the SMS alarm will automatically send an alarm message to the designated duty personnel's mobile phone, and support dialing and ringing before sending the message.
4) The on duty personnel can send SMS to modify the registers of the PLC. After the operation is successfully completed, the SMS alarm will send a confirmation message to notify the on duty personnel.
5) After the alarm is generated, the device power can be cut off through the relay output of the SMS alarm. Can be disarmed or deployed via SMS.
6) PLC register values can be sent to the duty personnel's mobile phones at regular intervals.
7) You can make a phone call to control the PLC. The SMS alarm controller can complete the control without answering, and there is no need for mobile phone call fees.
8) Support power failure alarm option, send SMS to the on duty personnel when the controller loses power.

Application areas:
1: Remote debugging, maintenance, alarm, control, and payment collection of PLC.
2: Detection and alarm of temperature and humidity, smoke, water leakage, broken glass, access control, etc. in the computer room.
3: Remote opening or closing of industrial equipment such as motors, water pumps, solenoid valves, etc.
4: Switch status feedback, such as power outage alarm, cable anti-theft, etc.
5: Remote monitoring of dry contact signal status.
6: Remote communication of data between industrial equipment and on-site sensing devices.
7: Wireless intelligent control for street lights, landscape lights, and urban lighting.

8: Remote monitoring of water tower and high-level water tank levels, and alarm of reservoir, water tower, and water tank levels to the administrator's mobile phone.

Product Features

1. Directly supporting PLC communication protocol, specifying register addresses and alarm conditions in the module can complete alarm configuration without the need for PLC programming.

2. Timed control: It can achieve periodic timing of year, month, and day, or hourly timing control. Example: From Monday to Friday, 8:00-17:00, turn on the air conditioning.

3. It is possible to control relay output or modify PLC registers based on various complex logical expressions. Example: When input 1 is closed and input 2 is open or the temperature is greater than 50 degrees, output relay 1 is closed

4. Can achieve active inquiry of SIM card balanceTo prevent the occurrence of outstanding fees.

5. The status of the SMS controller can be sent at regular intervals, such as signal strength and whether there is currently an alarm. During SMS control, the SMS controller will send an execution report to ensure completion of the execution.

6. You can make a phone call to control the output or modify the communication register.

7. When an alarm occurs, you can call the relevant person in charge and play the voice.

8. Strong communication capability, supporting MODBUS protocol and various PLC specific protocols from Siemens, Mitsubishi, and Ohm. It can achieve PLC SMS control, SMS maintenance, SMS alarm, SMS payment reminder, etc.

9. Strong anti-interference ability, four layer PCB, Saibao industrial grade certification. Siemens original industrial grade SMS module. 4KV pulse group anti-interference test, 8KV air discharge. Can be directly installed in high-voltage electrical cabinets containing frequency converters and high-power equipment.

It can be directly installed in electrical cabinets containing high-power equipment and is suitable for use in harsh electromagnetic environments.
3: High priority alarms can be set to require SMS confirmation. If the on duty personnel do not confirm this alarm, the alarm information will be continuously sent to the on duty personnel at the set time interval. And you can first call the duty personnel's mobile phone and then send a text message.
4: The SMS alarm can send device information at regular intervals to ensure that the on duty personnel are always aware of the equipment situation and take preventive measures.
