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
