Program memory sits at 448K Words, enough for complex sequencing, motion, or process loops. Expandability tops out at 80 modules spread across up to 7 racks, so the I/O count scales with the machine. Communication ports are RS-232C and USB — the RS-232C covers legacy HMIs or drives; USB handles programming via CX-One. The CPU mounts on a backplane, not DIN rail, so plan the rack layout accordingly. ## Backplane mounting and rack sizing The CPU installs into a CS1-series backplane and supports up to 7 racks with 80 modules. Program memory is 448K Words.","metaTitle":"Omron CS1H-CPU67H PLC CPU, 448K Words, 80 Modules","metaDescription":"Omron CS1H-CPU67H PLC CPU in active production. 448K word memory, expandable to 80 modules over 7 racks.
