GE IC693CPU341 – Single-Slot CPU Module | Series 90-30 PLC Platform
Engineering Background
The GE IC693CPU341 is a production-proven CPU module designed for the GE Fanuc Series 90-30 programmable logic controller platform — one of the most widely deployed mid-range PLC families in discrete manufacturing, process control, and building automation. Introduced as a cost-optimized single-slot solution, the IC693CPU341 delivers deterministic scan performance and robust I/O capacity for applications where reliability and long service life are non-negotiable requirements.
Product Positioning
Targeted at maintenance engineers, system integrators, and OEM machine builders who require a direct drop-in replacement or expansion CPU for existing Series 90-30 rack infrastructure. The IC693CPU341 eliminates the need for full system migration, protecting capital investment in installed base hardware while restoring full operational capability.

Proven Application Environments
- Discrete manufacturing: assembly lines, conveyor control, machine tool sequencing
- Process industries: pump station control, HVAC automation, water treatment
- Building automation: access control integration, lighting management systems
- OEM machinery: packaging equipment, printing presses, material handling
- Maintenance replacement: direct swap for failed IC693CPU341 units in live production systems
Engineering Advantages
- Single-slot footprint — preserves adjacent rack slots for I/O expansion modules
- SNP/SNPX protocol support — compatible with GE HMI panels, SCADA systems, and programming terminals via RS-232
- Deterministic scan execution — predictable ladder logic performance for time-sensitive control loops
- Backward compatibility — operates within existing Series 90-30 5-slot, 10-slot, and expansion rack configurations
- Proven field longevity — widely documented MTBF in 24/7 industrial environments
System Architecture & Signal Flow
The IC693CPU341 occupies Slot 1 of any Series 90-30 baseplate. The CPU communicates with local I/O modules via the Series 90-30 backplane bus and with remote expansion racks via the Bus Expansion Module (BEM). Program execution follows a standard PLC scan cycle: Input Scan → Program Execution → Output Scan → Communications Service. The RS-232 port supports point-to-point SNP connections to a programming device or HMI, enabling online monitoring, program upload/download, and forced I/O operations without interrupting the control scan.

Technical FAQ
Q: Is the IC693CPU341 compatible with Proficy Machine Edition software?
A: Yes. Proficy ME supports the IC693CPU341 for program development, upload/download, and online diagnostics via the RS-232 SNP connection.
Q: Can this CPU be used in an expansion rack?
A: No. The IC693CPU341 must be installed in Slot 1 of the main (local) baseplate. Expansion racks do not support CPU modules.
Q: What is the maximum I/O capacity with expansion racks?
A: The Series 90-30 platform supports up to 512 discrete I/O points across local and remote expansion racks when using the IC693CPU341.
Q: Is a battery required for program retention?
A: Yes. A lithium backup battery (IC693ACC301 or equivalent) is recommended to retain user program and data memory during power loss.
Q: Do you provide a warranty?
A: All units carry a 90-day functional warranty. Contact support@konmask.com for warranty claims and RMA procedures.
