Functional Description

IC695CMM002 is a serial communications module developed by GE Fanuc. It is a part of Fanuc RX3i Series, specifically designed to enhance communication capabilities within the RX3i PACSystems PLCs. This module is a key component for integrating various serial communication protocols, making it suitable for a wide range of applications.

Features

• The module is equipped with two independent, isolated serial ports. These ports can operate autonomously, allowing for simultaneous communication across different protocols and devices without interference. The isolation ensures that electrical disturbances on one port do not affect the other, enhancing the reliability of the system.
• By default, the module supports full duplex communication, enabling simultaneous two-way data transmission on both ports. It can handle multiple serial protocols, including RS232 and RS485/422, making it adaptable to various industrial communication needs. Additionally, with the appropriate firmware, the module can also be configured for half duplex communication, where data transmission occurs in one direction at a time.
• The module is designed to function in a wide range of environmental conditions, with an ambient operating temperature range of 32 to 140 degrees Fahrenheit (0 to 60 degrees Celsius). This makes it suitable for use in various industrial settings, from controlled environments to more challenging field conditions.
• Up to six modules can be installed in the main PACSystems RX3i backplane, offering scalability for systems that require multiple communication channels. This flexibility allows for extensive customization and expansion of the RX3i PACSystems to meet the specific needs of different applications.

Protocol Support

It is designed to manage both master and slave protocols efficiently. The supported protocols include:

• Modbus Slave
• Modbus Master
• DNP3 Slave
• DNP3 Master
• CCM Slave
• Serial I/O Protocol

This wide range of supported protocols makes the module suitable for diverse applications, from simple device control to complex industrial automation systems.

Installation and Hot-Swapping

• One of the standout features is its hot-swapping capability. This means the module can be safely installed or removed from the PACSystems RX3i backplane without needing to power down the entire system.
• This feature is crucial for minimizing downtime and maintaining continuous operation in critical industrial environments.

Power Requirements

The serial communications module operates with internal power ratings of:

• 0.115 Amps at 5 Volts DC
• 0.7 Amps at 3.3 Volts DC

 LED Indicators

The module features several LED indicators to provide real-time status information about the module's operation and port activity. These LEDs are crucial for troubleshooting and monitoring the performance of the module.

MODULE OK LED

The MODULE OK LED provides an overall status of the module, indicating whether the module is functioning correctly or if there are any issues. The different states of the LED are as follows:

• Off: The module is either not receiving power from the RX3i backplane or has failed its self-test. This indicates a power or initialization failure.
• Solid Green: The module has been successfully configured and is operating normally. This is the ideal status, indicating the module is ready for use.
• Blinking Green (Rapidly): The module is in the process of executing power-up diagnostics. This indicates the module is performing self-checks after being powered on.
• Blinking Green (Slowly): The module has not yet received configuration from the CPU. If the module does not successfully receive its configuration, it will continue blinking slowly in this mode.
• Blinking Amber: An error has occurred. The MODULE OK LED will blink amber to signal a fault, and the specific error code can be determined by the blink pattern. The error codes are as follows:
  
  • 1 = Watchdog expired
  • 2 = RAM error
  • 6 = Invalid CPU Master Interface version
  • 7 = CPU heartbeat failure
  • 8 = Failed to get semaphore

PORT FAULT LED

The PORT FAULT LED indicates the operational status of the module's communication ports. It helps identify whether there are any issues with the ports:

• Green: All enabled ports are functioning correctly, with no faults present.
• Amber: A fault is detected on at least one of the enabled ports. This indicates that one or more ports are experiencing issues that need attention.

Port STATUS LEDs

Each communication port has its own STATUS LED, which provides information on the activity and configuration of the port:

Blinking Green: The port is active, and data transmission is occurring. The blinking green light also indicates that the data rate of the port matches its configuration, ensuring proper communication and data transfer.
