Producing a Tag to a ControlNet PLC-5 controller
To produce a tag that a ControlNet PLC-5 controller can consume:
1. Determine the type of data to produce?
Then:
Create a user-defined data type that contains an array of INTs with an even number of
elements, such as INT[2]. When you produce INTs, you must produce two or more.
Create a produced tag and select the user-defined data type you created.
Create a produced tag and select the DINT or REAL data type, as appropriate.
Create a user-defined data type that contains an array of DINTs or REALs, as appropriate.
Create a produced tag and select the user-defined data type you created.
2. In RSNetWorx software, open the ControlNet configuration for the
target ControlNet PLC-5 controller, insert a Receive Scheduled Message
and enter the following Message size:
If the produced tag contains:
INTs
DINTs
REALs
3. In the RSNetWorx software, reschedule (save) the network.
The ControlNet PLC-5 controller does not perform type checking. Make
sure the PLC-5 data type can correctly receive the DriveLogix produced
tag to ensure proper data is being received.
When a ControlNet PLC-5 controller consumes a tag that is produced by
a Logix5000 controller, it stores the data in consecutive 16-bit integers.

Then, for the Message size, enter:
The number of integers in the produced tag
Two times the number of DINTs or REALs in the produced tag.
For example, if the produced tag contains 10 DINTs, enter 20 for
the Message size.
