Features:
- Independent programmable processor with two serial ports
- Supports MegaBasic, CCM, and Modbus RTU operation
- Interfaces ASCII devices without loading the normal PLC scan
IC693PCM301 is the programmable serial-computing option for modular Series 90-30 systems.
A local application can format messages, manage peripherals, or act as an RTU master while exchanging data with the PLC CPU.
Its memory, battery, and CPU-baseplate location distinguish it from a simple communication interface.
The General Electric IC693PCM301 Series 90-30 programmable coprocessor module may remain available for quotation and installed-system support from Apter Power.

Coprocessor application resources
- MegaBasic: Custom programs execute in the module rather than as ladder logic.
- Total RAM: The coprocessor contains 192 Kbytes of memory.
- User space: Approximately 47 Kbytes are available for the MegaBasic application.
- Retention: The onboard battery supports retained program and data functions.
Protocols and devices
- Port count: Two serial channels connect supported peripherals or communication peers.
- CCM: The module can provide GE Fanuc CCM exchanges.
- Modbus RTU: RTU master operation supports polling compatible serial devices.
- ASCII handling: Custom code can format data for terminals, printers, readers, and instruments.
Rack and CPU requirements
- CPU baseplate: IC693PCM301 must be installed with the modular CPU, not in an expansion rack.
- Excluded CPUs: Embedded CPU311, CPU313, and CPU323 do not support the module.
- Project exchange: PLC and coprocessor data areas are coordinated by the installed application.
- Battery service: Program retention depends on maintaining the required battery condition.
Supported peripheral uses
- Barcode collection: Serial readers can pass product identity into the PLC process.
- Weighing systems: Scales and other ASCII instruments can be polled and parsed locally.
- Operator terminals: Text terminals or CRTs can exchange formatted prompts and responses.
- RTU networks: The coprocessor can act as a Modbus RTU master for distributed serial devices.
