Proper Grounding An important subject to consider is the use of ground pins. There are two pins labeled GND. Pin 7 is the signal ground and must be connected to the distant device to complete the circuit. Pin 1 is the chassis ground, but it must be used with care. The chassis is connected to the power ground through the green wire in the power cord and must be connected to be in compliance with the electrical code. The problem is that when units are connected to different electrical outlets, there may be several volts of difference in ground potential. If pin 1 of each device is interconnected with the others via cable, several amperes of current could result. This condition may not only be dangerous for the small wires in a typical cable, but may also produce electrical noise that causes errors in data transmission. That is why Tables A-1 and A-4 show no connection for pin 1. Normally, pin 7 (signal ground) should only be connected to the chassis ground at one point; if several terminals are used with one computer, the logical place for that point is at the computer. The terminals should not have a connection between the logic ground return and the chassis.
Features Single slot CPU Provides 1 Mbyte of battery-backed memory in the same slot (up to 512 Kbytes available for use by ladder diagram application program) Supports floating point calculations Up to 12K discrete inputs and outputs (any mix - simplex mode only); 2048 voted discrete inputs, 2048 voted discrete outputs Up to 8K analog inputs (simplex mode only) and 8K analog outputs (simplex mode only); 1024 voted analog inputs 0.4 microseconds per boolean function 64 MHz, 80486DX2 microprocessor Supports IC660/IC661 I/O (and IC697 I/O in simplex mode only) Programmed by MS-DOS, or Windows software products running on Windows 95 or Windows NT over Ethernet TCP/IP or through the SNP port. Configurable data and program memory Battery-backed calendar clock Three position operation mode switch Password controlled access Remote programmer keyswitch memory protection Four status LEDs Software configuration (No DIP switches or jumpers) Reference information inside front door 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.
