Communicating with Devices on an ControlNet Link
Producing a Tag
Produced data must be of DINT or REAL data type or an array or structure.
You can use a user-defined structure to group BOOL, SINT, and INT data to
be produced. To create a produced tag:
1.
You must be programming offline.
2.
In the controller organizer, double-click the Controller Tags folder and
then click the Edit Tags tab.
3.
Select the tag that you want to produce, or enter a new tag, and display
the Tag Properties dialog box.
4.
Make sure the tag is controller scope.
5.
Select the “Produce this tag” check box. Specify how many controllers
can consume the tag.
You can produce a base, alias, or consumed tag.
The consumed tag in a receiving controller must have the same data type as
the produced tag in the originating controller. The controller performs type
checking to ensure proper data is being received.
Produced tags require connections. The number of connections depends on
how many controllers are consuming the tags. The controller requires one
connection for the produced tag and the first consumer. Then, the controller
requires an additional connection for each subsequent consumer.
Consuming a Tag
A consumed tag represents data that is produced (broadcast) by one
controller and received and stored by the consuming controller. To create a
consumed tag:
