GE Fanuc Emerson | Series Five

About

Series Five PLCs were designed as GE’s mid‑range controllers, combining features from the earlier Series One, Three and Six families. They use 6‑ or 8‑slot base units, modular CPUs and a range of I/O including analog and motion modules, and can expand to thousands of points using remote racks. Programming is via the vintage Logicmaster 5 software. While robust and modular, Series Five hardware is decades old and lacks Ethernet or modern programming environments. Keep it running if you must, but plan to replace it with a contemporary PAC.
