Communication and Networking Chapter 6
Remote connections depend on the communication module. The number of
connections supported by the module will determine how many connections
the controller can access through that module. See the EtherNet/IP
Performance User Manual, publication E
NET-AP001, for detailed guidance
on connections used by network components.
Produced/Consumed Tags in RSLogix
In Logix, the tag values are communicated between networked controllers by
configuring the tags as produced tags and consumed tags.
The value of a produced tag can be multicast or unicast across an Ethernet
network where it can be read by consumed tags in other controllers on the
same network.
Part of the configuration of a consumed tag defines the controller that
contains the equivalent produced tag.
Besides communicating over an Ethernet network, values of produced and
consumed tags can be transmitted via ControlNet and the backplane of Logix
controllers.
Changing the value of a consuming tag will not affect the producing tag.
No programming is required to configure produce/consume connections in
contrast to the complex programming to communicate with S5
communication modules.
