4.3 RSLogix 5000 assemblies
When the PLX51-DL-232 operates in a Logix “owned” mode, the Logix controller
establishes a class 1 cyclic communication connection with the PLX51-DL-232. An input
assembly is exchanged at a fixed interval. The provided UDTs convert the input arrays
into tag-based assemblies. Refer to the Additional Information section in this document
for more information on the input UDTs. There are no Output or Configuration
assemblies.
