System and Interface Modules play a crucial role in the architecture of programmable automation systems. These modules are designed to connect different parts of the control system, link expansion racks to the main controller, provide internal bus communication, or act as interfaces to various system components. Unlike standard I/O or dedicated communication processors for external networks, these modules often handle the structural and internal communication needs within the PLC or distributed I/O system itself. They ensure seamless data flow and signal exchange between modules, enabling complex and distributed automation solutions.
