The GE Fanuc IC693CPU351 is a single-slot central processing unit module designed for the Series 90-30 Programmable Logic Controller platform. It features an embedded 80386EX processor operating at a speed of 25 MegaHertz to deliver efficient computational execution across localized automation loops. Running on firmware release 9.00 or higher, this unit implements firmware-based software floating-point emulation, ensuring full logical execution of floating-point math blocks without requiring a separate hardware coprocessor. The module provides a total of 240K bytes of user memory alongside comprehensive diagnostic communication handling, featuring three built-in serial ports that natively support SNP, SNPX, and RTU protocols. Engineered to function within high-density plant topologies, it supports advanced firmware sequencing routines such as Sequential Event Recording, automatic user flash RAM configuration retention, and custom modem autodialing for real-time remote telemetry management.

Features

Single-slot modular form factor designed to fit directly into any standard Series 90-30 CPU baseplate.
Integrated 25 MHz 80386EX processor delivering a typical scan rate of 0.22 milliseconds per 1K of Boolean logic contacts.
Firmware-driven floating-point emulation supporting standardized industrial math function blocks.
Configurable memory mapping supporting up to 16K of %R register memory, 8K of %AI analog input memory, and 8K of %AQ analog output memory via DOS programming software.
Built-in Sequential Event Recorder function block capable of logging up to 1024 samples of 32 individual discrete bit references.
Three independent embedded serial communication ports including dedicated front-panel interfaces for point-to-point or multidrop configurations.
Advanced keyswitch logic control supporting transitions into configured STOP IO SCAN or STOP NO/IO states regardless of the initial PLC mode.

Applications

Centralized processing cores for multi-baseplate industrial Series 90-30 PLC automation systems.
Remote site telemetry monitoring installations using custom modem interfaces and automated pager enunciation tracking.
High-speed discrete manufacturing lines requiring precise execution tracking via Sequential Event Recording.
Multi-drop serial networks deploying localized data synchronization over SNP, SNPX, or RTU protocols.

Power Supply Connector	Secondary internal bus interface linking the CPU to the third serial communication port resident on the primary power supply unit.

Installation Guidelines

To secure structural mounting integrity and safeguard module firmware logic against volatile transient corruption across the backplane, execute the configuration and installation cycle according to precise engineering rules.

CRITICAL WARNING: VOLATILE MEMORY DELETION RISK

Modifying, clearing, or rewriting the central processor firmware directly within flash memory will automatically reset and purge all diagnostic status tables, application code logic, configuration settings, and preset SNP ID mappings resident within the local RAM matrix. Verify that a comprehensive copy of your operational settings is securely backed up before performing firmware modifications.

Execute RAM-To-Flash Backup Procedure

Prior to running hardware configuration transfers, manually save current configuration parameters, status tables, and ladder blocks directly from the transient volatile RAM block into long-term Flash memory storage zones.

Establish Serial Programming Download Link

Interconnect a computer running MS-DOS 3.3/Windows 95 or newer via an RS-232 to RS-485/422 converter setup. If required, deploy the IC690ACC901 Mini Converter Kit to establish an isolated link to the embedded serial port matrix.

Restore Application Data and Configure Mappings

Following the seating or upgrade process, write user instructions back from storage into active RAM memory. Note that the custom station SNP identification string cannot be auto-loaded and must be assigned independently using a dedicated Hand-Held Programmer or configuration module interface.

Product Documentation

Technical Datasheet (PDF) Complete specifications and technical drawings.

Esta unidade de processamento requer um coprocessador de hardware separado para executar operações matemáticas?

Não. Este módulo depende de emulação de ponto flutuante baseada em firmware para processar blocos matemáticos de ponto flutuante diretamente no núcleo central de processamento.

O que acontece com o programa lógico armazenado na RAM se o firmware for atualizado?

Modificar ou alterar o firmware do módulo apaga automaticamente o conteúdo volátil da RAM. Todo o código lógico, configurações e registros de status devem ser totalmente salvos e restaurados após a atualização.

Como a string de ID SNP da estação pode ser reatribuída após uma limpeza de inicialização do sistema?

O identificador SNP não pode ser preenchido a partir de um bloco de restauração de memória coletiva. Ele deve ser inserido independentemente via a pasta de configuração de programação ou utilizando um Programador Portátil separado.

Qual é o critério de desempenho da taxa de varredura física para este conjunto de processamento?

O módulo opera com um processador nativo de 25 MHz, mantendo uma taxa de varredura de execução básica de 0,22 milissegundos por 1K de lógica de contato booleana padrão.
