Migration Path | Rockwell Automation has discontinued 1771 I/O along with the PLC-5 platform. Published successor for the 1771 I/O: the equivalent ControlLogix 1756 I/O module.
A like-for-like replacement or a repair keeps the existing program, wiring and panel layout; a migration is a project. Both are listed on this page so the choice can be made on lead time and budget. | ||
