Product Description of IC693PCM301

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.

Technical Specifications of IC693PCM301

The GE Fanuc IC693PCM301 Programmable Coprocessor Module (PCM) is an industrial automation computer manufactured by GE Fanuc as a memory and processing power expansion device for programmable logic controllers from GE Series 90-30. The total memory capacity of this coprocessor module is 192 KB and there is a dedicated MegaBasic memory with a capacity of 47 KB. The GE Fanuc IC693PCM301 Programmable Coprocessor Module can be installed by insertion in any available slot in a Series 90-30 backplane except for the first slot that is specifically designated for the system’s central processing unit or main computer board. It is not designed to work with additional expansion racks, but only with the main PLC backplane. Communication with serial networks and devices is possible by using built-in serial ports for the Modbus RTU and GE Fanuc CCM communication protocols.

The GE Fanuc IC693PCM301 Programmable Coprocessor Module (PCM) is able to keep its random access memory contents safe during power interruptions by means of a backup lithium battery. Communication with handheld configuration devices is possible, but it requires separately sold IC690CBL701/702/705 serial communication cables. The GE Fanuc IC693PCM301 Programmable Coprocessor Module has a rated current consumption of 425 milliamps when it is connected to a 5 Volts DC power supply. One of the most notable features of this PCM is that it can connect to serial devices such as serial printers, bar code readers, industrial scales, ASCII devices, or RTU master devices, in order to integrate them into the user control platform. There are 2 user modes available: the “RUN” mode for normal operation and the “PROGRAM” mode when changes to the control logic need to be made.
