Appendix B
Produce and Consume Tags
You can produce a base tag, alias tag, or consumed tag. Produced data can be
the following:
•
A tag of DINT or REAL data type
•
An array of DINT or REAL elements
•
A user-defined structure with any type of elements. Use a user-defined
structure to group BOOL, SINT, and INT data
The consumed tag must have the same data type as the produced tag in the
originating controller. The controller performs type checking to be sure proper
data is being received.
