Configuring Digital Outputs
You can wire digital output channels to the following variable type and data structures:
BOOL (the
TK9_DO_Compact (provides three elements)
TK9_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.
TK9_DO_COMPACT and TK9_DO_FULL (Digital Outputs)
The data structures for digital inputs (TK9_DO_COMPACT and TK9_DO_FULL)
provide the elements detailed in the tables.
Table 16:
TK9_DO_COMPACT Structure for Digital Outputs
Identifier Type
Description
Remarks
BOOL
Input state
The commanded state to be passed to the
output channel
Set to TRUE to energize
Set to FALSE to de-energize
BOOL
Line fault
TRUE: no field supply is present, no load is
connected, or a short circuit is detected
Discrepancy TRUE:
there is a discrepancy in current greater
than 1% between the channels of two modules in
a redundant configuration (†)
