7-24 Communicating with Devices on an ControlNet Link
Producing and consuming tags with a ControlNet PLC-5 controller depends
on the type of data.
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?
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:
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.

tagA DINT
If: And you are producing: Then:
INT na 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.
DINT or REAL Only one DINT or REAL value Create a produced tag and select the DINT or REAL data type, as appropriate.
More than one DINT or REAL 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.
If the produced tag contains: Then, for the Message size, enter:
INTs The number of integers in the produced tag
DINTs 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.
