Allen-Bradley ControlLogix User Manual

1756-6.5.3 - December 1999
B-4 Creating Produced and Consumed Tags
A produced or consumed tag cannot be larger than 500 bytes. The tag must
also fit within the bandwidth of the network. See the Logix5550 Controllers
User Manual, publication 1756-6.5.12 for more information.
You can only create a consumed tag when programming offline.
To consume data from a remote controller, use RSNetWorx for ControlNet
software to schedule the connection over the ControlNet network.
The produced tag in the originating Logix5550 controller must have the
same data type as the consumed tag in the other Logix5550 controller. The
Logix5550 controller performs type checking to ensure proper data is being
received.
Important: If a consumed-tag connection fails, all of the other tags being
consumed from that remote controller stop receiving data as
well.
You can display a list of consumed tags in the tag editor of the current
project.
Produced tags require connections. The number of connections depends on
the amount of data and how many controllers are producing and consuming
tags. For more information, see Appendix A.
