        Overview Manuals BASIC Runtime Serial Interfaces Program Memory Peripheral Integration

        Features:

        • Resident BASIC-52 processing handles serial, calculation, and data-manipulation tasks.
        • RS-232 and RS-422 interfaces connect compatible ASCII peripherals.
        • Direct PLC I/O and register access links background programs with Series Five control data.
        IC655APU500 is an intelligent module rather than a conventional block of field points. Its local processor runs BASIC code while exchanging selected information with the Series Five CPU.

        Serial communication can be tailored from 300 to 19,200 baud. Electrical standard, modem or direct-cable wiring, and character framing must match the peripheral.

        Program retention and capability depend on the fitted memory and hardware revision. A service plan should preserve code, configuration, and cartridge information before any exchange.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        How the module executes its application

        • Local processor: BASIC code runs in the module rather than in the PLC scan.
        • GE extensions: Additional commands read and write Series Five data.
        • Background tasks: Serial handling and calculations can proceed alongside ladder control.
        • Revision features: Later hardware adds string, interrupt, and buffer functions.

        Matching the port to the external device

        • RS-232: Use for compatible short-distance single-ended connections.
        • RS-422: Use the differential interface where the device and cable require it.
        • Data rate: Choose a common speed from the supported range.
        • Framing: Make parity, data bits, and stop bits agree at both ends.

        Protecting the installed BASIC application

        • Battery RAM: Retains editable program data while backup remains healthy.
        • Memory cartridge: Compatible RAM or EPROM options expand program storage.
        • EPROM use: A programmed device can hold a fixed production application.
        • Service backup: Save code and configuration before removing power.

        Connecting ASCII equipment to Series Five data

        • Device examples: Terminals, printers, readers, and scales can exchange characters.
        • Message parsing: BASIC code converts received text into usable values.
        • PLC exchange: GE commands move selected data to or from registers and I/O.
        • Commissioning: Prove the serial link before enabling automatic data actions.
        Description
        General Electric IC655APU500 is a Series Five ASCII/BASIC Module that performs serial communications and local processing alongside the PLC CPU. It can exchange information with compatible terminals, printers, barcode readers, scales, and other ASCII devices while reading or writing selected PLC data.

        A resident BASIC-52 environment in IC655APU500 includes GE Fanuc extensions for Series Five I/O and register access. The module executes its program with its own processor and memory, allowing character handling, calculations, or peripheral transactions to proceed without representing every received character as ordinary ladder I/O.

        Both RS-232 and RS-422 electrical interfaces are available on IC655APU500 with selectable asynchronous data rates. The chosen interface, connector pinout, baud, parity, and message framing must match the peripheral, which makes cabling and port setup the first checks when a restored BASIC program receives no characters.

        Battery-backed RAM supports editable development on IC655APU500, while an optional EPROM can retain a finalized program image. Hardware revision matters because revision C and later added language and communication-buffer capabilities; an earlier unit therefore should not replace a later one until the installed program's dependencies have been reviewed.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why should an IC655APU500 program be backed up before module replacement?
        Under normal IC655APU500 service conditions, battery-backed RAM may contain the only working BASIC application and port settings; preserve the source, memory configuration, and revision dependencies before power is removed.
        What should be checked when IC655APU500 sends no readable serial data?
        When verifying IC655APU500, confirm RS-232 versus RS-422 wiring, connector pinout, baud rate, parity, stop bits, and whether the peripheral expects a modem or direct connection.
        Can IC655APU500 be treated as an ordinary Series Five I/O card?
        The practical answer for IC655APU500 is clear: No. It is an intelligent background processor with serial ports and PLC data commands, so troubleshoot its program, memory, and communication path separately from field point mapping.
        Why might BASIC code work on one IC655APU500 revision but not another?
        While restoring IC655APU500, programs using later string, interrupt, or communication-buffer functions require revision C or newer hardware; identify those dependencies before substituting an earlier unit.
        With IC655APU500, how can serial faults be separated from BASIC logic faults?
        During IC655APU500 startup checks, use a known cable or loopback where appropriate, verify character framing, and confirm port activity with a minimal transmit/receive routine before testing the full application.
        What memory choice is suitable for a finalized IC655APU500 program?
        In the IC655APU500 signal path, battery RAM supports editing, while a compatible programmed EPROM can provide a fixed application image; select the option that matches the maintenance and recovery plan.
        What should be documented for an IC655APU500 peripheral connection?
        At the IC655APU500 rack position, record electrical interface, cable pinout, station role, data rate, framing, protocol text, and how the BASIC program maps received data into PLC registers.
