GE Fanuc IC693 Series 90-30: CPU, I/O & Power Supply Reference

Overview

The GE Fanuc IC693 Series 90-30 is a versatile and widely used PLC system across various industries, including automotive and food & beverage. Despite its age, it remains a staple in many plants due to its reliability and modular design. The series 90-30 CPU, particularly the IC693CPU374, has been a workhorse, providing robust control solutions. However, with parts becoming end-of-life, plant managers face the challenge of migration versus like-for-like replacement.
Engineering Tip:

Consider stocking critical spare parts for the GE Fanuc IC693 series to mitigate downtime risks associated with obsolete components.

CPU Specifications

The IC693CPU374 is the flagship CPU of the Series 90-30, offering advanced features for its time. Below are its specifications:
Parameter Specification
CPU Memory 240 KB
Scan Time 0.2 ms/K
I/O Capacity Up to 4096 I/O points
Communication Ports Ethernet, Serial RS-232
Voltage 5V DC
Current Draw 1.5 Amps
The IC693CPU374 supports programming via ladder logic and function block diagrams, adhering to IEC 61131-3 standards. This ensures ease of integration with other systems and compatibility with software like Proficy Machine Edition.
Warning:

Ensure that the CPU's current draw does not exceed the power supply's capacity to prevent hardware failure.

I/O Capacity and Modules

The GE Fanuc IO modules for the Series 90-30 provide expansive customization options. With a capacity of up to 4096 I/O points, the system supports various modules, including discrete, analog, and special function modules. Modules like the IC693MDL645 and IC693ALG391 can be integrated to handle digital and analog inputs/outputs, respectively. Plant engineers often face the challenge of selecting the right combination of modules to meet specific process requirements without overloading the system's capacity.

Power Supply Requirements

Power supply is crucial for reliable operation of the GE Fanuc IC693 series. Models such as the IC693PWR321 provide 5V DC output, necessary to power CPUs and IO modules. Proper sizing of the power supply is essential to accommodate the current draw of all connected components.
Engineering Tip:

Always use a power supply with a capacity slightly higher than the total expected load to allow for future expansion and avoid overloading.

Communication Protocols

The Series 90-30 supports multiple communication protocols, enhancing its capability to integrate within diverse industrial environments. Protocols such as Ethernet/IP for high-speed data exchange, and Modbus TCP for device interoperability, are supported. Utilizing these protocols enables seamless connectivity with other systems, such as the Allen-Bradley 1756-L73 or Siemens 6ES7-314-6CH04-0AB0, facilitating centralized control and monitoring.

FAQs
