Navigate the Function Block Editor Interface Chapter 2

The Enable Line feature can have two data sources:

• If an input uses Enable Line to bind with an input point or other

function block’s output, the input retains this point’s data value.

• If an input uses Enable Line in an unbound capacity, the input

uses the default constant value (which you can set on each

instruction’s property page).

TIP

The EDS file for a device must explicitly specify support for this

functionality to be available. If a device’s EDS file does not

support this feature, this functionality will not be available.
