Communication interface module

Communication interface module is an important part of control system. Its functions mainly include data exchange and signal transmission. The control system is mainly composed of controller, actuator, motor and power supply. Various components of the control system, such as microprocessor, DSP, CPU, memory card and so on, all use serial ports for communication, so that each part can cooperate with each other to achieve functions. The control system consists of hardware and software. The hardware part is divided into two parts: hardware (such as PC, relay, power supply, signal converter, etc.) and software (such as video surveillance, fault alarm, etc.).

1. Application field of communication interface module

The application of communication interface module in industrial control is very wide, can be used in all kinds of factories, can also be used in petroleum, chemical, metallurgy and other industries. Especially in the petrochemical industry, which has a strong demand for power, a communication interface module with fast switching ability is needed, so as to realize automatic switching and fast transmission of control signals. Therefore, electrical connection has always been a very important component of industrial automation devices. Although the degree of industrial automation is increasing, the traditional controller is still playing its main function. It is matched with various communication interface modules, such as communication interface, computer management system and so on. Because in the industrial control system must use a large number of sensors with different working ability and adaptability of different hardware to form a series of control modules there are many kinds, so this kind of components need to be programmed and configured on a variety of software, so the communication interface module has become an indispensable and indispensable part of the development process. Based on this consideration, many communication interface module devices with different models and communication functions have appeared in the manufacturing process of different manufacturers. Their design and application are very successful and have been widely used.

2. Application environment

At present, there are three types of industrial communication interface modules sold in the domestic market: A. Industrial site communication interface module, mainly applied in industrial production field, can be used for workshop monitoring and other scenarios. For example, data communication between various devices in the control system, as well as various applications, such as the control signal data rate and timing data; B. There are various devices in the communication lines, such as computers, workstation servers, network equipment, etc. C. The equipment in the PLC system is connected to the communication system and has various functional requirements, such as PLC monitoring, field status monitoring, fault alarm, etc.; D. Power supply mode used in the power supply system to solve problems such as power supply shortage and power damage; E, DVB; D and other transmission lines. B. Inter-equipment communication provides a choice for the technical personnel of the project. B can send data to the communication equipment (PC) in various ways, and connect to the controlled equipment through the PC; Or communicate the equipment with the controlled system; Or transmit data to the controlled system.
