Intended Use

Intended for distributed Remote I/O rack applications. Adapters and scanners connect 1771 I/O chassis to a PLC-5 or ControlLogix processor over Remote I/O or ControlNet, so I/O can sit near the equipment across large plants, mills and treatment facilities.

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.

Under a ControlLogix controller, the existing 1771 rack can stay in service as Remote I/O through a 1756-RIO scanner while modules are converted.
The 1492 conversion wiring system (1492-CM1771 modules and pre-wired cables) lands the existing 1771 swing-arm wiring on the new 1756 module without touching field devices.
Rebuild the I/O tree in Studio 5000; 1756-RM085 covers how PLC-5 I/O addressing maps to Logix tags.

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.
