In-system upgradable firmware Functions The CPM 790 is a single slot programmable controller CPU which allows floating point calculations. The CPM 790 is programmed and configured with MS-DOS or Windows based programming software for use in Emergency Shut-Down (ESD), fire and gas, and other critical control applications. It communicates with I/O and smart option modules over the rack mounted backplane (IC697CHS750, 782, 783, 790, 791) by way of the VME C.1 Standard format. The CPM 790 must be used in conjunction with a Standalone C program which provides Triple Modular Redundancy (TMR) operating and autotest routines. It will not operate unless this program is included in the loaded application program.
