394
Digital Input Status
BYTE RO
Array size: 2
Bitfield
ON/OFF status of digital inputs from both the Base Control Module and the
inputs on the optional User Interface (C445UC... versions only). Bits 0-3
are the status for the inputs from the Base Control Module and bits 4-7
are the status of the 4 inputs from the Control User Interface.
395
Output Status
BYTE RO
Default: 0
Bitfield
The status of the output relays on the Base Control Module.
396
DIP Switches
WORD RO
Bitfield
Base Control Module DIP Switch Settings value. This is the weighted
binary value of the DIP switches that are currently set to the ON position.
397
Base Control Module
Control Bd Amb Temp
SINT16 RO
Units: °C
Ambient temperature measured on the PCB of the Base Control Module.
398
Base Control Module Max
Bd Amb Temp
SINT16 RW NV
Default: –40
Units: °C
Base Control Module Maximum ambient temperature for the PCB. This
value can be set (typically to -40).
