Functions

The Graphics Display Coprocessor (GDC) Module is a

coprocessor to the IC697 PLC CPU. It is programmed

to perform IC697GDS display functions when

coupled with the IC642PCM System 3000 Graphics

DisplayTerminal (GDT). It communicates with the

IC697 CPU over the system backplane.

Many Graphics Display Coprocessors can be sup-

ported in a single IC697 PLC system and can be

located in either the main rack or expansionracks.

Operation of the module may be initialized by de-

pressing a pushbutton on the module or by an

attached GDC (PCOP) development system. The sta-

tus of the GDC is indicated by three green LEDs on

the front of the module.

Serial Ports

Although both ports are RS-232 and RS-422/RS-485

compatible and the signals shown in both Table 1 and

Table 2 are available at each connector, the use of each

port is dedicated for GDC operation.

Port 1 (3PL) and Port 2 (4PL)

Port 1 (3PL) is normally connected to an RS-232 serial

COM port of a host computer for communications to

PCOP at 19.2 Kilobaud. Alternately, port 1 may be

connected to a serial RS-232 printer (see the Graphics

Display System User’s Manual to reconfigure Port 1).

Figure 3 shows typical cable connections for this

purpose and Table 1 shows the details of the RS-232

signals.

Video

The GDC provides EGA video resolution of 640 x 350

pixels. This video is provided to the GDT in the form of

RGB signals withsync ongreen. Video signalsfrom the

GDC are provided through the 9-pin D connector on

the module. The cable has three RG-179/Ucoaxial

cables, terminated with three BNC connectors at the

GDT end. Figure 5 shows wiring details of this cable.

SHELL

Figure 5. Video Cable Wiring Configuration

The three coax shields are soldered together and a

strandedAWG #16 (1.3 mm2) wire of less than three

inches is soldered to the connector shell and to the

shields. The shields are also tied to pin 1 of the con-

nector.

Configuration

There are no user DIP switches or jumpers on this

board for configuration. However, the IC640HWP77X

software must be loaded using PCM Development

Software (refer to the Graphics Display System User’s

Manual for details). The GDC must be configured with

IC641 Configuration software prior to use.

Status Indication

Three Status LEDs are available as shown in figure 2.

The top LED indicates the condition of the GDC mod-

ule, the bottom two LEDs indicate serial port and

backplane activity.

Controls

One pushbutton is provided on the module. Push

and hold for less than 5 seconds will restart an ap-

plication. Push and hold for more than 10 seconds

and the module factory default configuration will be

installed (this action will not clear memory but will

permit communication with the programmer using

factory default settings).

Batteries

A lithium battery(IC697ACC701) is installed as shown

in figure 2. This battery maintains user memory

when power is removed. Be sure to install the new

battery in the unused battery connector before re-

moving and discarding the old battery. If during

power-up diagnostics a low battery is detected, the

Module OK LED (top) will not stay on.
