Features:
- Variable analogue scan: multiplexes documented input channels.
- Selectible input range: provides +10 V and +5 V positions.
- Address and mode controls: retains word and scan selections.
The module combines analogue multiplexing with front-panel selections that directly affect range, addressing and scan behavior.
Channel wiring and switch positions must be captured together because either can change the value delivered to the controller.
A controlled loop test applies known inputs and compares controller readings before any analogue value is accepted for operation.
