Built-in RS-232C and USB ports handle programming and basic HMI links without an extra comms module. Software is CX-One. Approvals include CE, cULus, Lloyd, and NK, covering industrial control and marine applications. Documentation for compliance audits is available upon request via RFQ. ## Mounting & expansion Mounts on a backplane; CPU occupies one slot. Expansion reaches 80 modules across 7 racks via backplane interfaces. The RS-232C port is typically used for programming or Modbus communication; the USB port provides a direct connection to CX-One software. Both ports are active simultaneously; no port-switching DIPs.","metaTitle":"Omron CS1H-CPU66H PLC CPU, 256K Words Backplane","metaDescription":"Omron CS1H-CPU66H PLC CPU with 256K words program memory, backplane mount, RS-232C/USB communications, and CE/cULus/Lloyd/NK approvals.
