plc IO modules in industrial automation fieldbus communication.

Programmable Logic Controller (PLC) is the main industrial control systems. PLC systems and in-depth to use on the factory floor sensor / actuator interfaceplc IO module. IO module must meet stringent electrical specifications, can be divided into current, voltage, and plc digital input output io module. We will explore conditioning and solutions designers face, and touch these signals to meet the challenges of these challenges. These IO modules in the industrial field bus communication. Therefore, we will briefly explain the processor and interface solutions in industrial automation fieldbus communication.
