Interfaces field sensors and actuators with the controller at local or distributed I/O stations.
Check signal type, channel count, voltage/current, isolation, terminal base and environmental requirements.
Plan adapter, power segmentation, addressing, wiring, diagnostics and channel configuration before commissioning.
Create an old-to-new I/O mapping and validate electrical characteristics and field behavior channel by channel.
