Migration notes
- The Rockwell product page lists the category Functional Replacement but names no catalog number. TDL proposes ControlLogix 5580 sized by memory: 1756-L83E (10 MB), a family with an integrated EtherNet/IP port.
- ControlLogix 5560 controllers (1756-L61…L65) were discontinued on 01/06/2017; the product pages list Functional Replacement but name no catalog number, so the ControlLogix 5580 numbers in the table are TDL proposals sized by memory. The 1756-CNB/CNBR ControlNet modules have Rockwell-named replacements (1756-CN2/CN2R); for the 1756-DHRIO and 1756-RIO the Rockwell pages name no replacement.
Lifecycle status changes over time: confirm the current status on the Rockwell product page or in the Product Compatibility and Download Center before ordering.
