Migration notes

Functional replacement: 1756-IT16 (1756-TD002U p.190–191). Note: 1756-IT16 has no channel-to-channel isolation (1756-TD002U p.200); where per-channel isolation as on the IT6I is needed, see 1756-IRT8I.
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.
