GE IC697CPM790 64 MHz, 32-Bit Floating Point Central Processing Serial Port

Serial Port

The 15-pin D-connector provides the connection to an

RS-485 compatible serial port on the CPU (see Figure 3).

This port provides a serial connection to a Work Station

Interface board installed in the programming computer.

The serial connection can also be made from the serial

port on the CPU to the serial port on the programming

computer, or other serial device, through the

RS-422/RS-485 to RS-232 Converter (IC690ACC900) or

RS-232 to RS-422 Miniconverter (IC690ACC901).  This

connection can be made with available cables or you

may build cables to fit the needs of your particular

application.  See reference 3  for more information on

serial communications.

For more detailed information on configuration of TMR

systems and communications between PLCs in the

system, refer to the Modular Redundancy Flexible Triple

Modular Redundant (TMR) System User's Manual.

Programmer Connection, Ethernet TCP/IP

Connecting your programmer via an Ethernet TCP/IP

network requires installation of an Ethernet Interface

module in the PLC.  This can be either the Ethernet

Controller, IC697CMM741. or Ethernet Interface (Type

2), IC697CMM742.  Before connecting your

programmer and PLC to the Ethernet TCP/IP network

you must set the IP address in the Ethernet Interface.

After setting the IP address, connect the PLC and the

programmer running Windows software to the

Ethernet Interface.

For more detailed information on Ethernet TCP/IP,

refer to the TCP/IP Ethernet Communications (Type 2)

User's Manual, and the Windows programming

manual, GFK-1295.

Configuration

The IC697 CPU and I/O system is configured with

MS-DOS or Windows based programming software.

There are no DIP switches or jumpers used to

configure the system. The CPU verifies the actual

module and rack configuration at power-up and

periodically during operation. The actual

configuration must be the same as the programmed

configuration.  Deviations are reported to the CPU

alarm processor function for configured fault

response.  Consult Reference 1 for a description of

configuration functions.

Battery

A lithium battery (IC697ACC701) is installed as shown

in Figure 2.  This battery maintains program and data

memory when power is removed and operates the

calendar clock.  Be sure to install the new battery

before removing the old battery.  If during power-up

diagnostics a low battery is detected, the MODULE

OK LED (top LED) will not stay on.  Specific

indication of a low battery state is detailed in

Reference 2.

Removing a Module

The instructions below should be followed when

removing a module from its slot in a rack.

Grasp the board firmly at the top and bottom of

the board cover with your thumbs on the front of

the cover and your fingers on the plastic clips on

the back of the cover.

Squeeze the rack clips on the back of the cover

with your fingers to disengage the clip from the

rack rail and pull the board firmly to remove it

from the backplane connector.

Slide the board along the card guide and remove

it from the rack.
