Table 53 - 1756-OB16IEFS Module Input Data Tags—Data Output or Listen Only Connections
Name Data Type Tag Definition Module Definition
Fault DINT Fault Status—Indicates whether a point is faulted. If communication to the output
module is lost, then all 32 bits of the Fault word are set.
0 = No fault
1 = Fault
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].Data BOOL Data—Indicates the current value to be sent to the corresponding output point. If PWM is
enabled, this value will transition from 0 to 1 based on the PWM pulse train.
0 = Off
1 = On
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].Fault BOOL Fault Status—Indicates whether a point is faulted. If communication to the output
module is lost, then all 32 bits of the Fault word are set.
0 = No fault
1 = Fault
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].FuseBlown BOOL Fuse Is Blown—Indicates whether a fuse has blown due to a short or overload condition
for the corresponding point. All blown fuse conditions are latched and must be reset.
0 = Fuse is not blown.
1 = Fuse is blown and has not been reset.
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].PWMCycleLimitDone BOOL PWM Cycle Limit Done—Indicates whether the PWM pulse cycle limit defined in the
Pt[x].PWMCycleLimit configuration tag has been reached.
0 = The PWM cycle limit has not yet been reached. The bit resets to 0 each time the output
transitions to On to begin a new PWM cycle.
1 = The PWM cycle limit has been reached.
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].CIPSyncValid BOOL CIP Sync Is Valid—Indicates whether the module has synchronized to a valid CIP Sync
time master on the backplane.
0 = CIP Sync is not available.
1 = CIP Sync is available.
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
Pt[x].CIPSyncTimeout BOOL CIP Sync Timeout—Indicates whether a valid time master on the backplane has timed
out.
0 = A valid time master has not timed out.
1 = A valid time master was detected on the backplane, but the time master has timed
out. The module is currently using its local clock.
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
LocalClockOffset DINT Local Clock Timestamp—Indicates the offset between the current CST and the CIP Sync
value when a valid CIP Sync time is available.
Connection = Data
Output Data = Data
or
Connection = Listen Only
Output Data = None
