GE FANUC IC693PCM301 , Programmable Coprocessor Module , Series 90-30

Product Information

General: The IC693PCM301 is a Programmable Coprocessor Module (PCM) manufactured by GE Fanuc Automation North America, Inc. It is a high-functioning microcomputer that is compatible with the Series 90-30 Modular CPUs (Programmable Logic Controller system). The programming languages supported by the IC693PCM301 include Modbus RTU, GE Fanuc CCM protocols, MegaBasic and C. This version of the PCM has a total memory of 192K and a user MegaBasic memory of 47K.

Any CPU baseplate slot can host a IC693PCM301 with the exception of the CPU module's slot 1. Furthermore, a PCM doesn't function within the Expansion, Remote racks, or the Embedded CPU (CPU311, 313, or 323) rack.

Specific: The IC693PCM301 can be programmed to operate as a one or two independent CCM ports, a CCM port, and a MegaBasic application using one serial port or a MegaBasic application using one or both serial ports. These modules are used for communicating with programming terminals, CRTs, bar code readers, scales, printers, ASCII devices, RTU master devices, etc.

Ports: The two ports available on the IC693PCM301 are accessed by a common connector at the front of the model. IC693CBL305 Wye cables split out the two PCM port connections from the single connector on the faceplate. The module has three LED indicator lights. While one flashes to convey the condition of the module, the other two LED lights function to indicate activity in the respective ports. The latter group of indicators are subject to configuration by the user.

Restart Pusbutton: The restart pushbutton of the IC693PCM301 allows the user to change the mode of the module between "Run" and "Program". IC690CBL701/702/705 cables provide a direct RS-232 connection between the PCM and various programmers’ serial ports. These cables are not supplied with the PCM modules.

Memory: The RAM memory backup is handled by a lithium battery that is mounted on the inner side of the module's faceplate. It requires connection prior to instalment. The battery is to remain connected as long as the program in RAM memory is to be stored. It is advisable to disconnect and remove the battery during long term storage.
