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.
