Fieldbus is a kind of data communication and control technology used in factory automation workshop level monitoring and field equipment level. The PROFINET remote I / O is connected to the PLC and other controllers connected to the field bus through a communication line. In short, the PROFINET remote I / O is a data acquisition / transmission module with communication function and has no control and adjustment function. Only send the field data to the control center (such as PLC), or accept the data from the control center to control the field equipment. Remote I / O is a data acquisition / transmission module with communication function, which sends the field data to the control center (such as PLC), or receives the data from the control center to control the field equipment. It can realize the decentralized digital control and field communication network from the field equipment level to the workshop level monitoring, thus providing a feasible solution for realizing the comprehensive automation of the factory and the intellectualization of the field equipment.
