Configuring Digital Outputs
You can wire digital output channels to the following variable type and data structures:
BOOL (the <variable_name> 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
The commanded state to be passed to the
output channel
Set to TRUE to energize
Set to FALSE to de-energize
TRUE: no field supply is present, no load is
connected, or a short circuit is detected
TRUE: there is a discrepancy in current greater
than 1% between the channels of two modules in
a redundant configuration (†)

The commanded state to be passed to the

TRUE: no field supply is present, no load is
connected, or a short circuit is detected
TRUE: there is a discrepancy in current greater
