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)
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
<tagname>.DOP
BOOL
Input state
The commanded state to be passed to the
output channel
Set to TRUE to energize
Set to FALSE to de-energize
<tagname>.LF
BOOL
Line fault
TRUE: no field supply is present, no load is
connected, or a short circuit is detected
<tagname>.DIS BOOL
Discrepancy TRUE:
there is a discrepancy in current greater
than 1% between the channels of two modules in
a redundant configuration (†)
