Product Overview

The IC693CPU331-E serves as the central processing unit for the GE Fanuc / Emerson Series 90-30 Programmable Logic Controller (PLC). This 100% brand new, original module executes control logic, manages I/O data, and coordinates communication across the backplane. Equipped with 16K bytes of user memory, it is designed to handle moderate to complex automation tasks across a wide range of industrial applications.

Technical Specifications

Engineering Advantages

Efficient Logic Execution
The 80188 processor delivers a fast scan rate of 0.4 ms per 1K logic, ensuring responsive control for time-critical industrial processes.

Integrated Memory Management
With 16K bytes of user memory, the module supports ladder logic programs, configuration data, and register storage for medium-scale automation systems.

Streamlined System Architecture
Installs directly into the baseplate and communicates with all Series 90-30 modules via the backplane, eliminating the need for additional internal wiring.

Scalable I/O Capacity
Supports hundreds of discrete and analog I/O points, allowing system expansion as operational requirements increase.

FAQs

Does the IC693CPU331-E require a separate battery?
Yes. Program and register retention during power loss relies on the lithium battery housed in the power supply module. Regular battery checks are recommended.

Can I upgrade from an older IC693CPU331 to the "E" revision?
Yes. The “E” version is fully backward compatible and serves as a direct replacement without requiring program modifications.

How do I program this CPU module?
Programming is typically done using Proficy Machine Edition or Logicmaster 90 software via the RS-485 port on the system power supply.

What happens if the logic exceeds the 16K byte limit?
If memory requirements exceed 16K bytes, you will need to upgrade to a higher-capacity CPU within the Series 90-30 family, such as CPU350 or CPU364.
