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.

For detailed information on TMR systems, see

Reference 4. the IC66* Modular Redundancy Flexible

Triple Modular Redundant (TMR) System User's Manual.

Supported option modules include IC697 LAN Interface

modules, Programmable Coprocessor, Alphanumeric

Display Coprocessor,  Bus Controller for IC660/661 I/O

products, Communications modules, I/O Link Interface,

and all of the IC697 family of discrete and analog I/O

modules.
