GE IC697CPU731 12 MHz 32 Kbyte Central Processing Unit Configuration

Programmer Connection, Parallel

For a parallel interface (MS-DOS programmer only)

connect the programmer to the top port connector on

the Bus Transmitter Module (IC697BEM713) as shown

in Figure 1.  Consult  Reference 2 for a description of

programming functions.

Serial Port

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

RS-485 compatible serial port as shown in Figure 3.

This port provides a serial connection to a Standard

Serial COM port, or to a Work Station Interface board

installed in the programming computer. For more in

formation on serial communications, see references 1.

2. and 3.

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 the programmer connection via

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 config

ure 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.  Devi

ations are reported to the CPU alarm processor func

tion for configured fault response.  Consult Reference

1 for a description of configuration functions.

Batteries

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 be

fore removing the old battery.  If during power-up

diagnostics a low battery is detected the Module OK

LED (top) will not stay on.  Specific indication of a low

battery state is detailed in Reference 2.

Removing a Module

The following instructions 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.
