Configuring Digital Outputs
You can wire digital output channels to the following variable type and data structures:
 BOOL (the gives the commanded state)
 T9K_DO_Compact (provides three elements)
 T9K_DO_Full (seven elements)
The structures provide additional information about the output, such as line fault
status and discrepancy status.
Note: The controller writes its digital outputs once per application cycle; the digital
output variables are also updated once per application cycle.
T9K_DO_COMPACT and T9K_DO_FULL (Digital Outputs)
The data structures for digital inputs (T9K_DO_COMPACT and T9K_DO_FULL)
provide the elements detailed in the tables.
Table 13: T9K_DO_COMPACT Structure for Digital Outputs
Identifier Type Description Remarks
.DOP BOOL Output demand The commanded state to be passed to the
output channel
Set to TRUE to energize
Set to FALSE to de-energize
.LF BOOL Line fault TRUE: no field supply is present, no load is
connected, or a short circuit is detected
.DIS BOOL Discrepancy TRUE: there is a discrepancy in current greater
than 1% between the channels of two modules in
a redundant configuration (†)

output channel
Set to TRUE to energize
Set to FALSE to de-energize
.LF BOOL Line fault TRUE: no field supply is present, no load is
connected, or a short circuit is detected
.DIS BOOL Discrepancy TRUE: there is a discrepancy in current greater
