GE IC693CSE340 Single-slot State Logic CPU module

Description

In compact machine cells or standalone skids where operators need reliable PLC logic without dedicating rack space to a full CPU baseplate, the GE IC693CSE340 steps up as a streamlined State Logic processor tightly integrated into a single slot. Found in packaging fillers, pump control panels, and discrete assembly stations within larger industrial automation networks, it handles boolean sequencing, timers, counters, and basic data moves for applications that don’t demand heavy analog processing or Ethernet connectivity. Engineers specify the GE IC693CSE340 when retrofitting older relay panels or building modular skids that tie into a master Series 90-30 system, ensuring consistent ladder logic execution without the footprint of multi-slot CPUs. This keeps startup simple and maintenance familiar across GE Fanuc platforms used in food packaging, conveyor zoning, and utility sequencing.​

The GE IC693CSE340 thrives where scan performance matters more than memory depth—think rapid discrete control for sorters, fillers, or reject arms, where every millisecond counts toward throughput in control systems. Unlike bulkier CPUs, it fits directly into standard I/O racks, sharing the backplane with power supplies and field modules while offloading simple logic from the main plant controller. Plants leverage it for zone isolation, letting local decisions like jam clears or count-based diverters run autonomously yet report status back via serial links, minimizing wiring complexity in distributed setups​

Product Introduction & Positioning

The GE IC693CSE340 is a single-slot State Logic CPU module for GE Fanuc Series 90-30 PLC systems, embedding a dedicated processor optimized for high-speed boolean and state-based control in space-constrained applications. Powered solely from the rack’s 5 V backplane, it occupies one slot in any compatible baseplate, executing user programs up to 32 KB while interfacing directly with discrete and basic analog I/O modules. In the architecture, the GE IC693CSE340 acts as a lightweight co-processor or standalone brain, mapping inputs/outputs to its internal memory table and supporting serial communication for integration with HMIs or host PLCs.​

Positioned for entry-level to mid-tier discrete automation, the GE IC693CSE340 targets machines or subsystems where full-featured CPUs like the 350-series prove overkill, yet reliability under repetitive cycles is non-negotiable. Programmers use familiar Series 90-30 tools—handheld monitors or Logicmaster software—for configuration, making it a drop-in for crews upgrading from electromechanical relays or early PLCs. Its role emphasizes efficiency: fast scans through state logic instructions keep responses deterministic, ideal for OEM skids plugged into larger control systems without custom firmware.​

Key Technical Features & Functional Benefits

Built on a 20 MHz 80C188XL processor, the GE IC693CSE340 delivers a scan rate of about 0.3 milliseconds per 1K of boolean logic, prioritizing speed for contact-heavy rungs common in sequencing and event-driven machines. With 32 KB user program memory, plus register (%R) and bit (%M) storage, it handles complex state transitions, shift registers, and PID-light functions without external expansion, while EEPROM backs up critical data against power loss. This on-board retention means no battery swaps, boosting uptime in remote panels where access lags hours.​

Hardware integration shines in its single-slot form—490 mA draw from 5 V fits standard power supplies, with front-panel programming port and LEDs for run/fault/status at a glance. Rugged for industrial cabinets, it withstands vibration and EMI through backplane isolation, supporting up to 10-slot racks populated with compatible I/O for hybrid local/remote control. Diagnostics include self-tests on boot and interrupt-driven faults, letting technicians pinpoint wiring or logic issues via the handheld programmer without disassembly.​

The GE IC693CSE340 supports State Logic enhancements—to/otd coils, steps, and transitions—for streamlined programming of multi-phase sequences versus traditional coils, cutting ladder depth by half in applications like recipe followers or fault handlers. Serial ports enable SNP protocol for PC/HMI links or peer networking, extending its reach in control systems without added comm modules. Longevity comes from mature firmware; field reports show GE IC693CSE340 units logging decades with basic cleaning, as passive cooling and low component count minimize thermal wear.

Installation Notes & Maintenance Best Practices

Seat the GE IC693CSE340 in slot 1 of low-density racks to optimize backplane loading, confirming power supply capacity exceeds 500 mA headroom before populating I/O. Use shielded serial cable for programming ports in EMI zones, and verify firmware matches the handheld via status LEDs post-insert—no hot-swap here, as backplane glitches reset logic. Ground panels per NEC, isolating from motor circuits to protect scan integrity on long runs.otomasyonavm+2​

Quarterly wipe-downs clear dust from card edges; log run hours via diagnostics to predict EEPROM wear, though most GE IC693CSE340 outlast panels. Test state transitions annually against sequence charts, and swap only de-energized—live faults corrupt memory tables. Backup logic files religiously; restores take minutes versus rewrites.
