Designing Add-On Instructions Chapter 1

See Creating an Alias Parameter for a Local Tag on page 31.

Data Type

Parameters and local tags are used to define the Data Type that is used when

executing the instruction. The software builds the associated Data Type. The

software orders the members of the Data Type that correspond to the parameters

in the order that the parameters are defined. Local tags are added as hidden

members.

The Data Type for a Local Tag may not be:

• A multi-dimensional array or an object type, which includes all Motion

types, MSG, ALARM_ANALOG, and ALARM_DIGITAL.

• A data type used only for InOut parameters (MODULE).

The Data Type field is unavailable for members of a Local Tag.
