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 (†)
