Bit Name Description
8 GroupFault 0 = Good
1 = Any channel or module faulted/failed
PtFault INT Channel fault status; one bit per channel for channels 0…15:
0 = Normal
1 = Channel is faulted/failed
Open Wire INT Open wire diagnostic status; one bit per channel for channels 0…15:
0 = Normal
1 = Indicates open wire detected
ShortCircuit INT Short circuit diagnostic status; one bit per channel for channels 0 …15:
0 = Normal
1 = Indicates short circuit detected
Indeterminate INT Indeterminate diagnostic status; one channel per channel for channels 0…15:
0 = Normal
1 = Indicates indeterminate input voltage detected
Timestamps AB:1715:TIMESTAMP[16] TIMESTAMP array
One element per channel.
NB each timestamp is equivalent DINT[2] representing a 64-bit value (number
of microseconds since 1
st
January 1970). An AOI
‘SystemTime_64bit_Interpreted’ is available to convert such timestamps to a
more manageable format with individual values for Day, month, year etc.

Fault DINT, Binary Module fault bit:
0 when one module is present and reporting valid data, OxFFF_FFFF when no
modules are present, no Logix connection exists, or reported data is invalid.
Data INT Input state, one bit per channel for channels 0…15:
0 = Off/de-energized
1 = On, energized
