The IC698RMX016 is a redundant memory switch module (RMX) for the PACSystem RX7i programmable automation controller family.
The main function of this module is to serve as a node on reflective memory, or memory link between partner central processing unit (CPU) modules that form redundant pairs in highly critical applications. It is installed on the host frame of the RX7i backplane and is recommended to be installed in rack 3 or 4 to enable interrupt priority. In addition, it also supports other devices in the mainframe.
The module has the following features:
Dimensions: 6.299 inches wide x 9.187 inches high.
User memory: 16MB of SDRAM.
Power supply: The operating voltage is +5 V DC, the current is required to be 1.8A.
Optical fiber connector: Optical fiber LC connector and az zirconium ceramic core according to IEC 61754-20.
Insertion loss: The maximum insertion loss is 0.35dB and return loss is -30dB.
Operating temperature: Acceptable temperature range between -20°C and +85°C.
In practical use, the user would need to press the board into place without force, tighten the top and bottom screws of the panel, and then connect the board's TX cable to the RX connector of the next node, repeating until the last node in the ring routes its TX to the RX connector of the first node. After the power is turned on, the IC698RMX016 is initially powered in an unconfigured state where its light emitter is disabled. The redundant memory switch module does not run on the network until the RX7i CPU sends the hardware configuration to the module.
The main purpose of the IC698RMX016 module is as a redundant memory switch module for data exchange and storage in the PACSystems RX7i programmable automation controller family. Specifically, the module can act as a node on reflective memory, forming a memory link between partner central processing unit (CPU) modules of redundant pairs in highly critical applications. It can achieve high-speed and reliable data transmission through optical fiber connectors, and supports Daisy chain link mechanism connection to achieve data exchange between multiple nodes.
In addition, the IC698RMX016 module also has a variety of communication protocols and interface types, such as Ethernet, serial communication, etc., which can interact with other devices and systems for data transmission and control commands. It is usually used in industrial automation and control systems for data exchange and control with other devices (such as sensors, actuators, human-machine interfaces, etc.) to ensure the stability and reliability of the system.
In summary, the IC698RMX016 module is an important component for achieving highly reliable and stable data exchange, suitable for a variety of industrial automation and control systems requiring real-time data transmission and control.
