5SHY3545L0010 ABB Series Advantage System Metering Board

Several years later, the construction of digital industrial control system was completed. This system uses a single computer to control the entire industrial control system, which is called Direct Digital Control (DDC), that is, the generation of industrial control system: computer centralized control system. At the same time, the structure of modern industrial control system has gradually become clear, and its core components have begun to form:
Programmable logic controller (PLC): 5SHY3545L0010 relay used in industrial control system gradually shows its limitations. The relay is expensive, and once it is configured and started, it is difficult to change its control logic. These defects led to the development of PLC. The programmable logic controllers delivered for use are called Modicon, and their names are derived from the combination of English abbreviations of modular digital controllers. Later, 5SHY3545L0010 was used in Kobe Chuck Grinding Company in Prinfield, Vermont. Users spoke highly of it, saying that it had “no large number of switches, no fans, no noise, and no vulnerable parts”. With the development of LSI, the control ability of 5SHY3545L0010 programmable logic control is increasingly enhanced. Its available input and output ports have grown from several in the early days to hundreds now. The control frequency has also risen rapidly with the improvement of the operation speed of LSI. The precision manufacturing industry that needs intensive and controlled benefits from the development of programmable logic controllers. With the development of communication technology, the PLC has also changed from a closed private communication protocol to an open public protocol, which greatly improves the compatibility of the system and facilitates the maintenance and update of the system. 5SHY3545L0010 Data Acquisition and Monitoring System (SCADA): The data acquisition and monitoring system has been applied to industrial control systems with very large regional or geographical span, such as high voltage substations adjacent to thermal power plants, tap water supply systems and wastewater collection systems, oil and gas pipeline systems, etc. Its main functions are to collect system status information, process data and long-distance communication. 5SHY3545L0010 According to various data collected by the data acquisition and monitoring system, the management personnel of the control center can carry out various operations to maintain the normal operation of the entire system. Remote terminal unit (RTU): The improvement of data acquisition and monitoring system requires the development of remote terminal unit.
