1. Product introduction of plc wireless transmission module
GPRS communication is based on the existing communication network of mobile operators and is mainly used for data transmission. The purpose of Zongheng Intelligent Control’s development of PLC wireless communication control module is to enable people who do not know the knowledge of wireless communication and interconnection networks to realize PLC wireless communication control. Zongheng Intelligent Control’s GRM200 series modules use GPRS (the controller needs to insert the mobile phone SIM card) as a communication method to realize PLC wireless communication control. This module comes with 8 I/O inputs and 4 relay outputs, which can easily realize remote data collection and control. It can also be used as a simple PLC controller to realize timing control functions through simple configuration. The GRM200 series modules adopt a triple communication method that combines GPRS, SMS and phone dialing, which completely solves the instability problem of traditional GPRS modules. Even if the GPRS network is interrupted, PLC wireless communication control and long-distance control can be completed by SMS or phone calls. SMS control, SMS query, SMS alarm
Zongheng Intelligent Control provides comprehensive solutions including free host computer configuration software (which can also rely on OPC to support various configurations, WINCC, Kingview, Force Control, etc.), GRPS control module, and cloud monitoring. Customers only need to have a computer with Internet access, simply configure the GRM200, and the PLC can easily implement remote wireless monitoring without writing any programs.
2. Function overview of plc wireless transmission module:
1) As long as the computer has access to the Internet, it can use the configuration to remotely read and write PLC variables. Supports remote monitoring of PLC via mobile webpage.
2) At the same time, it supports reading and writing all PLC registers using mobile phone text messages to realize text message alarm and text message remote control.
3) ZHC2921 comes with digital input and analog input, which can replace the analog expansion module of the PLC system and reduce system costs.
4) If something goes wrong with the monitored equipment, ZHC2921 will automatically send an alarm text message to the mobile phone of the person on duty and display the alarm on the computer.
5) The person on duty can send mobile phone text messages or control ZHC2921 on the computer to complete equipment start and stop, parameter setting, fault reset, etc.
6) Device information can be sent to the mobile phone of the person on duty on time.
7) Ability to make phone calls to control equipment. ZHC2921 can be controlled without answering at one end, and there is no need for mobile phone call charges.
8) Supports mains power outage alarm and sends alarm text messages during power outage.
3. Features of PLC wireless communication control module:
