GE Fanuc IC693PCM300 — GE Fanuc, Programmable Coprocessor module

The IC693PCM300 is a programmable coprocessor module manufactured by GE Fanuc. It is designed to provide additional processing power to the GE Fanuc Series 90-30 PLC (Programmable Logic Controller) systems.

The PCM module acts as a separate processing unit that can execute complex calculations, data manipulation, and other tasks that the PLC may not be equipped to handle on its own. This is particularly useful in applications that require high-speed processing or extensive data analysis.

The module is equipped with a powerful 80386 microprocessor running at 16 MHz, and has 512 KB of battery-backed RAM for program storage. It also features a series of communication ports, including two RS-232 serial ports and an RS-485 serial port, allowing for easy integration with other devices or networks.

Programming the PCM module is done using GE Fanuc's Logicmaster software. This programming environment allows users to create custom programs using ladder logic, structured text, or function block diagram languages. The programs developed on the PCM module can be seamlessly integrated with the PLC's program, allowing for efficient control and coordination of the overall system.
