Produce and Consume Tags (interlock controllers)

If you are unsure of the maximum number of consumers, use a number 
higher than the actual number of consumers. Unused connections are 
deducted from the number of available controller connections.

When your controller produces a tag, any device that interfaces 
with a ControlNet network can consume the tag. However, when a 
non-Logix controller, such as a personal computer using a 1784-
PKTCS card, consumes the tag produced by a Logix controller, 
you must perform additional tasks in RSNetWorx for ControlNet 
software. 
 
Logix 5000 controllers can consume only controller-scoped user-created tags 
from another controller’s tag structure. The Logix 5000 controllers cannot 
consume I/O tags or tags aliased to I/O tags. 
Important: 
You can create consumed tags only when your Logix Designer project is offline. 
To consume a tag, perform this procedure. 
1.  Open the Logix Designer project that contains the controller that you 
want to consume the produced tag. 
2.  Make sure the controller producing the tag to be consumed is in the 
consuming controller’s I/O configuration, as shown in this example. 
Local ControlNet module in consuming controller’s chassis

3.  Make sure the communication format for the remote ControlNet 
module is None.
