The Ethernet Interface module (IC693CMM321) provides an interface that allows you to attach the

Series 90-30 PLC to an Ethernet LAN via an external transceiver and AAUI cable, and to

communicate with hosts and other control devices on the network.

The Ethernet Interface for the Series 90-30 PLC has client/server capability.  As a client it can

initiate communications with other PLCs containing Ethernet Interfaces.  This is done from the

ladder program using the COMMREQ Function Block.  As a server it responds only to requests

from other devices such as a Host computer running a Host Communications Toolkit application or

another Series 90-30 PLC acting as a client.

The Ethernet Interface allows you to:

Directly attach your PLC to an Ethernet network

Initiate transfer of data to the PLC from another device

Communicate simultaneously to multiple devices with up to 16 server connections

Interface with other GE Fanuc devices, as well as with devices from other vendors

Communicate from a Host computer (or other control device)

Diagnose and maintain your system using diagnostic and station management tools

The Ethernet Interface does not support the Series 90-30/20/Micro Hand-Held Programmer. 

Either one or two Ethernet Interface modules can be installed in any Series 90-30 baseplate.

The Ethernet Interface connects to an Ethernet network through an external SQE enabled

transceiver (GE Fanuc catalog no. IC649AEA102 or IC649AEA103 or equivalent.

See AppendixJ).  The following figure shows the layout of the Ethernet Interface.

The ELFD Controller Carrier provides a mounting platform for up to two SafetyNet Controllers (8851-LC-MT) .

It can also accommodate a Power Supply Monitor module (8410-NS-PS)

which can monitor the health of up to two 8913-PS-AC,

four 8914-PS-AC power supplies and the 12V supply to Intrinsically Safe Modules (when these are used) .

For each Controller there is a serial port connector and a manually operated ““Change State” button .

The Carrier also provides terminals that are used when earth leakage fault detection is required.

Installation

It is the responsibility of the OEM, system integrator,

or end user to properly install the PLC equipment for

safe and reliable operation.  Product manuals provide

detailed information about installation, startup, and

proper use of the PLC equipment.  The installation

manual, shipped with your PLC programming

software, describes how to properly install the equipment.

If the PLC installation must comply with supported

standards, such as FCC or CE Directives, please refer

to the Installation Requirements for Conformance to

Standards, shipped with the PLC programming

software, for additional guidelines.

Installation should not be attempted without refer

ring to the applicable Programmable Controller Installation Manual.

Connect the battery to either of the battery connec

tors on the module (see Figure 2).

Put the toggle switch in the STOP position.

Put the keyswitch in the Memory Protection OFF position.

Make sure that rack power is off.

Install the CPX 928 module in slot 1 of rack 0 (see Figure 1).

Turn on power

Operation, Protection, and Module Status

Operation of this module can be controlled by the

three-position RUN/STOP switch or remotely by an

attached programmer and programming software.

Program and configuration data can be locked

through software passwords or manually by the

memory protect keyswitch.  When the key is in the

protected position, program and configuration data can

only be changed by a programmer connected parallel

only (to the Bus Transmitter module).  The status of a

CPU is indicated by the seven green LEDs on the

front of the module.

Operating Temperature

The CPX 928 requires forced air cooling for proper

operation in ambient temperatures greater than 50C

(122 F).  A fan capable of 70 CFM (including filters)

should be located beneath slot 1 of the rack containing

the CPU.

Fan assemblies (IC697ACC 721. IC697ACC724. and

IC697ACC744) can be ordered for direct mounting on

the IC697 rack.  Refer to the applicable Programmable

Controller Installation Manual for detailed information.

User RAM Memory

The CPX928 has a built-in memory board with 6

Mbytes of battery-backed CMOS RAM memory for

user data (program, configuration, and register data) storage.

User Flash Memory

The CPX928 has 256K of built-in, non-volatile flash

memory for user data (program, configuraton, and

register data) storage.  Use of this flash memory is optional.

Firmware Storage in Flash Memory

This CPU uses flash memory for storing the operating

system firmware.  This allows firmware to be updated

without disassembling the module or replacing

EPROMs.  The operating system firmware is updated

by connecting a PC compatible computer to the mod

ule’s serial port and running the software included

with the firmware upgrade kit.

Functions

The CPX 928 is a single slot PLC CPU that is

programmed and configured by MS-DOS or

Windows based programming software to perform

real time control of machines, processes and material

handling systems. It communicates with I/O and

smart option modules over the rack-mounted

backplane using the VME C.1 Standard format.

Supported option modules include 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.
