Overview The digital input interface of a PLC is not complex. As we know, to enhance anti-interference capabilities, PLCs use optical isolators to isolate the input signals from the internal processing circuits. Therefore, the signal at the input end merely drives the internal LED of the optical isolator, which is then received by the phototransistor … Read more
In some industries, FCS has developed from PLC; in others, FCS has developed from DCS. Therefore, there are intricate connections between FCS, PLC, and DCS, along with essential differences.This article analyzes the characteristics and differences of the three major control systems: PLC, DCS, and FCS, pointing out their origins and development directions. PLC, DCS, FCS … Read more
