The IC698RMX016 is a redundant memory switching module (RMX) that is used with the PACSystem RX7i programmable automation controller family. The module is primarily used as a memory link between nodes on reflective memory or partner central processing unit (CPU) modules that form redundant pairs in high-critical applications. The module is installed in the chassis of the RX7i backplane and is recommended to be installed in rack 3 or 4 to enable interrupt priority, however, the module also supports other slots in the chassis.

The IC698RMX016 is equipped with 16 MB of static dynamic random access memory (SDRAM). The module is powered by 5 VDC and 1.8 amps from the backplane. The module measures 6.299 inches (width) x 9.187 inches (height). The available connectors for redundant memory switch modules are LC type optical fiber connectors according to IEC 61754-20. The connector material is zirconium ceramic ring with a maximum insertion loss of 0.35 DB and return loss of -30 DB. The module has an operating temperature range of -20 degrees Celsius to 85 degrees Celsius.

During the power-on, the module is not configured. The IC698RMX016 will run until the host RX7i CPU module sends the appropriate hardware configuration to the module. For general reflection operations, hardware configurations can be configured using various parameters, such as node ID, redundant transport mode, malicious master, network memory offset, and interrupt enable, but in redundant operations, the above parameters are automatically set by the CPU and cannot be configured.

The Rx7i PACsystem IC698RMX016 module is a redundant memory Xchange module or RMX module manufactured by GE Fanuc. It operates as a node on the reflected memory of the link between the RX7i system and the CPU. It has an operating voltage rating of 5 volts DC and a rated current of 1.8 amps. It comes with 16 MB of SDRAM user memory. It is compact in size, measuring 6.299 inches wide and 9.187 inches high. This module uses a maximum of 256 nodes per network. The IC698RMX016 communication module uses dynamic packet sizes of 4 to 64 bytes, which are controlled by the Xchange module.

The IC698RMX016 communication module uses a high-speed fiber optic network for data exchange. The front of the module is equipped with eight different LED indicators and a toggle switch that can be used to authorize role switching. Role switching is used to change the role of a module and helps prevent accidental activation. It has 2 on and off positions. It has a spring-loaded mechanism that is turned off by default. The IC698RMX016 module requires PacSystem with firmware version 2.00 to install. It is programmed using Logic Developer PC software. The connectors of the communication module are made of zirconium ceramic rings with a maximum insertion loss of 0.35dB. It has a return loss of -30 dB. There is an optical transceiver in the module which has 2 LC optical ports. There is a TX port for the transmitter and an RX port for the receiver.
