Functional Description

IC693CMM311R is a communications coprocessor module developed by GE Fanuc. It is designed to enhance the communication capabilities of Series 90-30 modular CPUs. This module offers a high-performance coprocessor specifically for these CPUs but is not compatible with embedded CPU models such as 311, 313, or 323.

Supported Communication Protocols

• GE Fanuc CCM (Control Communication Module): A proprietary protocol used for communication between GE Fanuc devices.
• SNP (Series Ninety Protocol): A protocol used for communication with GE Fanuc programmable logic controllers (PLCs).
• RTU (Remote Terminal Unit) Modbus Slave: A widely used protocol in industrial automation for communication between devices.

Features

• The module can be configured using specialized configuration software, allowing users to tailor the setup to their specific needs. For those seeking a simpler installation process, a default setup option is also available.
• Part of a broader range of communication modules available for the Series 90-30 platform. One notable module is the Programmable Coprocessor Module (PCM), a high-performance microcomputer that can be programmed in MegaBasic or C. This module is particularly useful for interfacing with devices such as Bar Code Readers, RTUs, and other ASCII devices, further expanding the capabilities of the system.

Serial Ports and Connectivity

Equipped with two serial ports:

• Port 1: Dedicated to RS-232 applications, a standard for serial communication transmission of data.
• Port 2: Capable of supporting either RS-232 or RS-485 applications. RS-485 is particularly useful for longer-distance communication and in environments where electrical noise might interfere with communication.
• Both ports are connected to a single connector on the module. To facilitate easier wiring, the module comes with a Y-cable (IC693CBL305), which separates the two ports, simplifying the installation and ensuring that the system is organized and efficient.

System Integration and Compatibility

• Multiple Module Support: A system with a CPU model 331 or higher can accommodate up to four IC693CMM311 modules. These modules are installed via the CPU baseplate, enabling scalable communication capabilities within the system.
• Datagram Management: In versions prior to 4.0, the module had a unique issue when both ports were configured as SNP slave devices. If a Cancel Datagram request with an ID value of -1 was received at either port, it would cancel all established datagrams on both ports within the same module. This behavior differed from the CMM711 module, where datagrams on separate serial ports did not interact. However, this issue was addressed and resolved in version 4.0, released in July 1996. For users with older versions of the module that experience this issue, repair services are available.

Frequently Asked Questions

What is IC693CMM311R?
It is a Communications Coprocessor Module developed by GE under VersaMax series.

What is the purpose of the Y-cable supplied with the module?
The Y-cable is provided to separate the two serial ports from the single connector on the module. This separation simplifies wiring and makes it easier to organize and connect the module within the system.

Can I configure the module?
Yes, it can be configured using specialized configuration software. For users who prefer a simpler setup, the module also offers a default configuration option.

What was the issue with older versions of the module, and how was it resolved?
In versions before 4.0, the module had an issue where both ports, when configured as SNP slave devices, would cancel all established datagrams on both ports if a Cancel Datagram request with an ID value of -1 was received. This issue was resolved in version 4.0, released in July 1996. Users with older versions can contact repair services for assistance.

What are the power requirements for the module?
The module requires an internal power supply of 400 mA at 5 VDC.
