Europe and the United States import a large stock of spare parts

With the strengthening of network capabilities, the control functions and control scopes realized by programmable logic controllers are expanding, which requires programmable logic controllers to achieve high-speed operation and real-time communication functions. Speeding up includes speeding up operation speed, speeding up data exchange with external devices, speeding up service processing of programming devices, and speeding up responses of external devices. In order to achieve high speed, some programmable logic controllers have been designed with communication functions in their cores. With the help of passive data buses, the bottleneck of the system is eliminated. This structure allows multiple processors and networks to be in one rack. It can be used without limitation, thus providing a high-performance distributed real-time control system solution.
