More Information

Overview Manuals Programming Serial Services Compatibility Applications

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.

All prices are shown in USD.

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.
Description
IC693PCM301 is a programmable coprocessor module with an independent processor for serial communication and application tasks outside the modular Series 90-30 ladder scan.

With IC693PCM301, the module provides two serial ports and supports MegaBasic, CCM, and Modbus RTU functions. Its 192 Kbytes of total RAM include approximately 47 Kbytes available to a MegaBasic application, with battery support for retained operation.

When integrating IC693PCM301, iC693PCM301 installs only in the CPU baseplate and is not supported with embedded CPU311, CPU313, or CPU323. Typical connections include terminals, barcode readers, scales, printers, and other ASCII equipment as well as RTU master applications.

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.
What kind of program runs in IC693PCM301?
The programmable coprocessor executes a MegaBasic application independently of the Series 90-30 ladder scan.
Can IC693PCM301 poll Modbus devices?
This programmable coprocessor supports Modbus RTU master operation for compatible devices connected to its serial ports.
Why is IC693PCM301 not accepted with CPU313?
Embedded CPU311, CPU313, and CPU323 systems cannot host IC693PCM301; use it only with a supported modular CPU and its CPU baseplate.
How much MegaBasic space is available in IC693PCM301?
A configured programmable coprocessor provides approximately 47 Kbytes of its 192 Kbyte memory for the MegaBasic user application.
Can IC693PCM301 communicate with a barcode reader?
Its custom serial code can receive and process ASCII data from barcode readers and similar peripherals.
Can IC693PCM301 be mounted in an expansion or remote rack?
No. IC693PCM301 belongs in a modular CPU baseplate, and slot 1 remains reserved for the CPU.
What files are needed to replace IC693PCM301?
Its service requires the coprocessor program and port setup in addition to the controller ladder project and hardware configuration.
