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

Identifier

Type

Description

Remarks

<tagname>.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

<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 (†)
