The CGR935 is a single slot programmable controller CPU which allows floating point calculations and is required for CPU redundancy applications. The CGR935 is programmed and configured by MS-DOS or Windows programming software to perform real time control of machines, processes and material handling systems. The CGR935 communicates with I/O and smart option (specialty) modules over the rack mounted backplane (IC697CHS750, 790, 791) by way of the VME C.1 Standard format. Supported option modules include all IC697 LAN interface modules, several Coprocessor modules, Bus Controller for IC660/IC661 I/O, Communications modules, and all of the IC697 family of discrete and analog I/O modules
