The GE Fanuc IC698CMX016 is a Control Memory Exchange (CMX) module designed for the RX7i PACSystem platform. This module enables deterministic, high-speed data sharing among multiple PLCs and compatible devices using reflective memory technology over fiber optic networks. The IC698CMX016 comes with 16 MB of SDRAM and operates independently of the CPU, so it does not consume any processing power from the main controller. It supports up to 256 nodes per network and delivers transfer rates from 43 MB/s to 174 MB/s depending on packet size. With its LC fiber optic ports and 2.12 Gbaud transmission speed, the IC698CMX016 is ideal for applications requiring real-time data synchronization across distributed control systems. This module occupies a single slot in the RX7i rack and requires Proficy Machine Edition Logic Developer PLC version 4.5 or later for configuration.
The GE Fanuc IC698CMX016 offers impressive performance metrics for demanding industrial networks. It features 16 MB of SDRAM with parity checking, which ensures data integrity during high-speed transfers. The communication interface consists of two multimode fiber optic ports with LC connectors, labeled TX and RX. These ports support a transmission speed of 2.12 Gbaud over distances up to 300 meters (984 feet). The module dynamically controls packet sizes ranging from 4 to 64 bytes. Specifically, the maximum network transfer rate reaches 43 MB/s for 4-byte packets and scales up to 174 MB/s for 64-byte packets. This flexibility allows the IC698CMX016 to adapt to different data payload requirements. The module draws 1.8 A from the 5 VDC backplane supply and operates within a temperature range of -20°C to +85°C. Its physical dimensions are 6.299 inches wide by 9.187 inches high, and it fits into a single slot of the RX7i rack.
The IC698CMX016 uses reflective memory technology to achieve deterministic data sharing across a distributed network. In a reflective memory system, any data written to the local memory automatically replicates to all other nodes on the network. This mechanism ensures that every connected PLC or device has an identical copy of the shared data set. Consequently, the IC698CMX016 eliminates the need for complex messaging protocols or master-slave polling schemes. Data updates occur in real time, so this module suits applications such as synchronized motion control, power plant coordination, and test cell automation. The module supports redundant transfer mode operation, which enhances network reliability by providing alternate data paths.
The GE Fanuc IC698CMX016 is network-compatible with the VMIC 5565 family of reflective memory devices. This compatibility means you can integrate the IC698CMX016 into existing reflective memory networks without replacing other components. Each node in the network connects to a VMIC 5565 device, and these devices are linked in a daisy-chain loop using fiber optic cables. The IC698CMX016 supports up to 256 nodes per network, offering substantial scalability for large-scale automation systems. Moreover, the module performs automatic network error detection, which helps maintain smooth and reliable data transfers. Because the IC698CMX016 is CPU-independent, network performance does not degrade even when the main processor handles heavy computational loads.
The front panel of the IC698CMX016 includes four LED status indicators that provide clear operational feedback. These LEDs are labeled OK, CONFIG, OWN DATA, and SIGNAL DETECT. The OK LED indicates that the module has power and functions correctly. The CONFIG LED lights up when the module has proper configuration through Machine Edition software. The OWN DATA LED shows that the module is transmitting its own data onto the network. Finally, the SIGNAL DETECT LED confirms that the fiber optic signal exists on the receive port. These diagnostic lights significantly simplify troubleshooting and network validation during installation and maintenance.
To use the GE Fanuc IC698CMX016, you must configure it using Proficy Machine Edition Logic Developer PLC, version 4.5 or later. This software environment allows you to set network parameters, define packet sizes, and configure redundant transfer modes. The module also requires an RX7i CPU with firmware release 2.00 or higher. Additionally, the RX7i rack must include a compatible power supply that can deliver sufficient current to the backplane. The IC698CMX016 does not require any user programming for basic operation because its functionality is hardware-defined. However, you can customize data mapping and transfer triggers through the VME bus outputs. These outputs initiate data transfers over the network based on user-defined conditions.
Installing the GE Fanuc IC698CMX016 is a straightforward process. First, power down the RX7i rack completely to avoid any electrical hazards. Next, select an available slot on the backplane. The IC698CMX016 occupies a single slot and can go into any position, except for slot 1 which is typically reserved for the CPU. Slide the module into the chosen slot until it seats firmly against the backplane connector. Secure it with the retaining screws. Then, connect the fiber optic cables to the TX and RX ports, ensuring that you observe the correct transmit and receive orientation. For daisy-chain networks, connect the TX port of one node to the RX port of the next node. Finally, power up the system and use the front-panel LEDs to verify that the module initializes correctly and detects the fiber optic signal.
