Pt[x].PWMFaultValueStateDuration SINT Fault State Duration—Defines the length of time that the output state remains in the
Fault mode state before transitioning to a final state of On or Off. The Fault mode state is
defined in the FaultValue tag.
Valid values:
• 0 = Hold forever (default). Output remains in Fault mode for as long as the fault
condition persists.
• 1, 2, 5, or 10 seconds

Pt[x].PWMCycleLimit SINT PWM Cycle Limit—Defines the number of pulse cycles to occur when the output turns
On:
• If the corresponding bit in the PWM.ExecuteAllCycles tag is set, the configured number
of cycles will occur even if the output turns Off.
• If the corresponding bit in the PWM.ExecuteAllCycles tag is cleared, the configured
number of cycles will occur only if the output remains On. For example, if the cycle limit
is 4, and the output turns Off after 3 cycles, the 4th cycle will not occur.
The default cycle limit is 10.
Requires PWM to be enabled via the PWM.Enable tag, and cycle limits to be enabled via
the PWM.CycleLimitEnable tag.

Pt[x].PWMMinimumOnTime REAL PWM Minimum On Time—Defines the minimum length of time required for the output
to turn On. Requires PWM to be enabled via the PWM.Enable tag.
Valid values:
0.0002…3600.0 seconds
or
0…100 percent Connection = Data

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 Module Fault word are set.
0 = No fault
1 = Fault Connection = Data
Output Data = Scheduled per
Point
or
Connection = Listen Only
Output Data = None
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 = Scheduled per
Point
or
Connection = Listen Only
Output Data = None
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 = Scheduled per
Point
or
Connection = Listen Only
Output Data = None
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 = Scheduled per
Point
or
Connection = Listen Only
Output Data = None
