Product Overview

The GE IC693APU300K is a specialized intelligent I/O module designed for the GE Fanuc Series 90-30 programmable logic controller(PLC)platform,functioning as a dedicated ASCII communication co-processor that offloads serial data handling from the main CPU.By managing low-level serial protocols and data formatting independently,the GE IC693APU300K enables seamless integration of ASCII-based peripheral devices—such as barcode scanners,label printers,weigh scales,operator terminals,and legacy HMIs—into modern or legacy automation systems without burdening the central processor or requiring custom ladder logic for character-level parsing.

Engineered for industrial environments,the GE IC693APU300K supports both RS-232 and RS-485 physical layers through a configurable DB-9 connector,with selectable baud rates up to 38.4 kbps and full-duplex or half-duplex operation.Its onboard firmware interprets common ASCII control sequences,manages handshaking(XON/XOFF or hardware RTS/CTS),and buffers incoming/outgoing data streams,allowing the Series 90-30 CPU to interact with external devices using simple block-transfer instructions.This architecture significantly simplifies programming,improves system responsiveness,and enhances reliability in applications where real-time data exchange with serial instruments is critical.The GE IC693APU300K mounts directly into standard Series 90-30 I/O racks or remote bases,making it a versatile solution for both centralized and distributed control architectures.

Main Features and Advantages

Dedicated serial processing offloads CPU workload:The GE IC693APU300K handles all low-level serial communication tasks—including character reception,framing,error checking,and buffer management—freeing the main PLC CPU to focus on core control logic.This separation improves scan time consistency and system stability,especially in data-intensive applications like production tracking or quality inspection.

Flexible interface configuration:With DIP switch settings,users can easily configure voltage levels(RS-232 vs.RS-485),baud rate,parity,and handshaking mode without software changes.This adaptability allows the GE IC693APU300K to connect to a wide array of legacy and modern ASCII devices using standard cabling,reducing integration complexity and eliminating the need for external protocol converters.

Robust industrial design:Built to withstand electrical noise,temperature fluctuations,and mechanical vibration,the GE IC693APU300K features opto-isolated signal paths and conformal-coated circuitry,ensuring reliable operation in harsh factory environments.Its deterministic communication behavior makes it suitable for time-sensitive tasks such as reading scale weights during filling operations or capturing barcode data on moving conveyors.

Seamless Series 90-30 integration:The module appears as a standard I/O block to the CPU,accessible via%AI and%AQ memory addresses.Engineers can read received strings or write commands using simple block-move instructions in Logicmaster or Proficy Machine Edition,drastically reducing development time compared to bit-banging serial routines.

Proven longevity in brownfield systems:Even decades after its introduction,the GE IC693APU300K remains indispensable in facilities where Series 90-30 systems interface with irreplaceable serial equipment.Its continued availability supports lifecycle extension strategies without costly platform migrations.

Application Field

The GE IC693APU300K is widely used in manufacturing and process industries where ASCII-based serial devices remain integral to operations.In pharmaceutical packaging lines,it interfaces with label printers and vision systems to ensure batch traceability.In food processing plants,the GE IC693APU300K reads weight data from checkweighers and communicates with metal detectors using standardized ASCII protocols.Similarly,in automotive assembly,it captures VIN barcodes from handheld scanners and sends job data to torque tools or test stations.

Beyond discrete manufacturing,the GE IC693APU300K plays a key role in utility and infrastructure sectors.Water treatment facilities use it to collect data from legacy pH meters or chlorine analyzers that output readings via RS-232.Power plants employ it to communicate with older turbine controllers or annunciator panels that lack modern Ethernet interfaces.In all these scenarios,the GE IC693APU300K acts as a cost-effective,reliable bridge between aging instrumentation and robust GE Series 90-30 control logic—preserving capital investment while maintaining operational continuity.

Installation and Maintenance

Pre-installation preparation:Install the GE IC693APU300K into a powered Series 90-30 I/O rack,ensuring proper slot alignment and secure latching.Configure the DIP switches according to the target device’s communication parameters(baud rate,parity,RS-232/485 mode)before powering up.Use shielded twisted-pair cable for RS-485 or standard serial cable for RS-232,grounding the shield at one end only to avoid ground loops.Verify pinout compatibility between the GE IC693APU300K’s DB-9 and the peripheral device.

Maintenance recommendations:Periodically inspect the GE IC693APU300K for loose terminal connections,corrosion on the DB-9 pins,or communication errors logged in the PLC program.If data corruption occurs,confirm baud rate and parity settings match on both ends and check for EMI sources near serial cables.Although the module has no user-serviceable parts,its solid-state design ensures long life;however,in high-noise environments,consider adding ferrite cores to serial lines.Always keep a spare GE IC693APU300K on hand for rapid replacement,as reconfiguration is minimal due to DIP-switch-based setup.
