Table 78 - 16-channel Digital Input, Duplex
Tag Name Data Type Definition
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
Status DINT, bit-field Redundancy and power status:
Bit Name Description
0 ModAFault 0 = Good
1 = Fault or module not present
1 ModBFault 0 = Good
1 = Fault or module not present
8 GroupFault 0 = Good
1 = Any channel or module faulted/failed
9 ModAGroupFault 0 = Good
1 = Any channel or module A faulted/failed
10 ModBGroupFault 0 = Good
1 = Any channel or Module B 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:
