Product Overview

The GE Fanuc IC693CPU352 is a high-performance single-slot CPU module designed for the Series 90-30 Programmable Logic Controller (PLC) system. Equipped with an 80386EX processor operating at 25 MHz, this module provides 240 KB of configurable user memory. It is engineered for demanding industrial applications requiring hardware-based floating-point math capabilities and extensive I/O capacity.

Features

• Processing Power: Built-in hardware floating-point co-processor for complex mathematical calculations.
• Memory: 240 KB of user-configurable memory for robust program storage.
• Communication: Features three total serial ports, including an RJ45 port (Port 1), a 9-pin D-sub connector (Port 2), and a power supply connector port supporting SNP and SNP-X protocols.
• I/O Scalability: Supports up to 2048 discrete inputs and 2048 discrete outputs, with the ability to manage up to 7 expansion or remote I/O baseplates.
• Operational Control: Integrated physical keyswitch for selecting Run/Stop modes and enabling/disabling memory protection.
• Data Security: Removable 3.6V lithium battery for long-term retention of user programs and register data.

Technical Specifications

Installation Guidelines

• Slot Placement: This module must be installed in the CPU slot of the primary 90-30 baseplate.
• Handling: Always observe ESD (Electrostatic Discharge) precautions when handling the module to prevent damage to internal circuitry.
• Grounding: Utilize the shield ground connector located on the bottom of the module to mitigate electromagnetic interference (EMI) and electrical noise in high-interference environments.
• Battery Installation: Ensure the lithium battery is correctly seated to maintain data integrity during power cycles.
• Safety: Always disconnect power from the baseplate before inserting or removing the CPU module.

Applications

• Water Treatment: Management of pumping stations, chemical dosing, and monitoring equipment.
• Logistics: Control of automated conveying systems and vertical storage stackers.
• Renewable Energy: Pitch control and condition monitoring for wind turbine systems.
• Packaging: Multi-axis synchronous control and precise positioning for high-speed lines.

FAQ

What is the primary distinction between the CPU351 and CPU352?

The IC693CPU352 includes a hardware-based floating-point math co-processor, whereas the IC693CPU351 does not support this feature.

How many baseplates can this CPU manage?

The module supports a total of 8 baseplates: one local CPU baseplate and up to 7 additional expansion or remote I/O baseplates.

What protocols are supported by the serial ports?

The module supports SNP and SNP-X slave protocols on the power supply connector, and both RTU slave and SNP/SNP-X master/slave protocols on Ports 1 and 2.
