Tag Description
Simplex Digital Output Module Tags Include
Fault DINT Fault (Radix = Binary) - 0 at least one module present, data good
- FFFFFFFF No Logix connection, data bad, all additional tags are not valid
ReadBack SINT (Radix = Binary) - 1 bit readback per point 0…7
GroupFault BOOL - 1 if any point on the module is faulted/failed
PtFault SINT (Radix = Binary) - 1 bit per point 0…7; 1 if point is faulted/failed
NoLoad SINT (Radix = Binary) - 1 bit per point 0…7; 1 indicates no load
ShortCircuit SINT (Radix = Binary) - 1 bit per point 0…7; 1 indicates short circuit
Duplex Digital Output Module Tags Include
Fault DINT Fault (Radix = Binary) - 0 at least one module present
- FFFFFFFF No Logix connection, all additional tags are not valid
ReadBack SINT (Radix = Binary) - 1 bit readback per point 0…7
ModAFault BOOL - 0 Good, 1 fault or module not present
ModBFault BOOL - 0 Good, 1 fault or module not present
GroupFault BOOL - 1 if any point on either module is faulted/failed
ModAGroupFault BOOL - 1 if any point on Module A is faulted/failed
ModBGroupFault BOOL - 1 if any point on Module B is faulted/failed
PtFault INT (Radix = Binary) - 1 bit per point 0…15; 1 if point is faulted/failed on both modules
ModAPtFault INT (Radix = Binary) - 1 bit per Channel 0…15; 1 if channel has failed on module A
ModBPtFault INT (Radix = Binary) - 1 bit per Channel 0…15; 1 if channel has failed on module B
