GE IC693CMM301

Description

Product Description

The GE IC693CMM301 is a critical CMM (Communications and Memory Module) for the GE Fanuc Series 90-30 Programmable Logic Controller (PLC). This module serves two essential functions: it expands the controller’s memory capacity for storing larger user logic programs and data, and it provides an additional serial communication port. The GE IC693CMM301 was a vital upgrade component for extending the capabilities of the popular 90-30 platform, allowing users to manage more complex automation tasks and communicate with additional devices like HMIs, bar code readers, or other PLCs. Its robust design ensures reliable operation in industrial settings.The flexibility provided by the GE IC693CMM301 made it a common choice for system upgrades and expansions. When planning an enhancement for a Series 90-30 system, integrating the GE IC693CMM301 was a standard method to overcome memory limitations and add a versatile communication channel.

Product Parameters

• Function: Combination Communications and Memory Module.
• Memory Capacity: Provides additional user memory (RAM) for program and data storage; specific capacity varies (e.g., 16K words common).
• Communication Port: One RS-232/RS-422/RS-485 serial port, software-configurable.
• Port Protocol Support: Supports SNP (Serial Network Protocol) for peer-to-peer communication, RTU (Remote Terminal Unit) for Modbus RTU slave/master functions, and ASCII In/Out.
• Compatibility: Designed for use with the GE Fanuc Series 90-30 PLC CPU units (e.g., models ending in -311, -331, etc.).
• Installation: Plugs directly into a dedicated slot on the Series 90-30 CPU unit.
• Power: Powered directly from the CPU backplane.

Advantages and Features

The primary advantage of the GE IC693CMM301 was its dual functionality in a single module slot, providing a cost-effective solution for systems needing both extra memory and an extra serial port. Its configurable serial port supported multiple industry-standard protocols, offering great flexibility for interfacing with a wide range of serial devices without requiring additional hardware. The module enhanced the longevity and capability of the widely deployed Series 90-30 systems, protecting user investments.

Application Cases in Key Fields

• Material Handling: Added to a 90-30 controlling a conveyor system to provide the memory needed for complex sorting logic and to add a serial port for communicating with a weigh scale controller via Modbus RTU.
• Water Treatment: Used in a pump station control panel to expand program memory for additional pump sequencing logic and to establish a serial link (SNP or Modbus) to a remote SCADA master station.
• Packaging Machinery: Implemented to allow communication with a serial-based servo drive controller for precise positioning while also accommodating a larger, more advanced machine control program.
• Building Automation: Enabled a 90-30-based HVAC control system to communicate via Modbus with a network of room thermostats and to store extensive scheduling and trending data.

Comparison with Competing Products

Within the GE Fanuc 90-30 ecosystem, the alternative was often to use separate, dedicated modules—a memory module (like the IC693MEMxxx) and a separate serial communications module (like the IC693CMM321). The GE IC693CMM301 offered a more compact and integrated solution. Compared to communication modules from contemporary platforms like the Siemens S7-300 or Allen-Bradley SLC 500, the GE IC693CMM301’s strength was its simplicity and deep integration with the 90-30 hardware and programming software (VersaPro, Proficy Machine Edition). It was a specific solution for a specific, very popular platform.

Selection Suggestions and Precautions

1. CPU Compatibility: Verify that your specific Series 90-30 CPU model supports the GE IC693CMM301. Not all early CPUs support all CMM modules.
2. Memory vs. Protocol Need: Clearly define your primary need. If you only need massive memory, a pure memory module might be better. If you only need multiple serial ports, dedicated communication modules exist. The GE IC693CMM301 is the optimal choice when both needs are moderate.
3. Battery Backup: The added memory is typically volatile (RAM). Ensure the CPU’s battery is functional and healthy to retain the program and data during power outages.
4. Protocol Configuration: Correct configuration of the serial port’s protocol, baud rate, and address within the PLC programming software is crucial for successful communication.
5. Legacy Product Status: The GE Series 90-30 and the GE IC693CMM301 are legacy products. For new projects, consider modern successors like the Emerson (formerly GE) RX3i platform. For maintaining existing systems, source from reputable industrial automation suppliers. Technical details can be confirmed via the legacy documentation: GE IC693CMM301. Always have a backup of the PLC program before installing or replacing this module.
