It mounts on a backplane (same rack as I/O, special function, and communications modules) and is programmed using the CX-One software suite. ## Integration notes Communication ports are RS-232C and USB. RS-232C covers programming and connection to legacy HMIs or serial devices; USB handles fast program downloads. Expand via the backplane to up to 80 modules (7 racks) without extra interfacing.","metaTitle":"Omron CS1H-CPU65H PLC CPU, 128K Words","metaDescription":"Active production. 128K-word memory, RS-232C, USB.
