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:
