391 V Negative Sequence Real SINT16 RO Monitor Negative Sequence Voltage, Real Component
392 V Negative Sequence
Imaginary
SINT16 RO Monitor Negative Sequence Voltage, Imaginary Component
393 Frequency Scaled UINT16 RO
Units: 0.01Hz
Line frequency scaled in 0.01Hz.
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).
