It is the unit to specify when the panel needs to scale out to 80 Modules across 7 Racks, the maximum expansion headroom the CS1H class carries. Built-in comms are RS-232C and USB, so a laptop running CX-Programmer talks to the rack without an extra serial card on day one. Approval footprint covers CE, cULus, Lloyd, and NK, which clears the unit for marine and shipyard panels alongside the usual industrial destinations. ## Where the CS1H CPU sits in a panel Mounting is backplane only — the CS1H-CPU64H drops into the CPU slot of a CS1H power-supply / backplane assembly; I/O and comms cards stack to the right up to the 80-Module (7-Rack) ceiling. Because comms are native RS-232C and USB, the only wiring decision on a retrofit is whether the existing serial drop is still the right one or whether the team is moving the engineering port to USB at the rack face. CX-One is the software envelope — CX-Programmer handles the logic edit, and the rest of the suite (HMI, drives, networking) tags onto the same project file, which matters when an integrator is asked to hand off a complete programming archive at SAT.","metaTitle":"Omron CS1H-CPU64H PLC CPU, 64K Words, 7 Racks","metaDescription":"Omron CS1H-CPU64H CS1H CPU module, 64K Words program memory, expandable to 80 modules across 7 racks, CX-One toolchain, CE / cULus / Lloyd / NK approvals.
