GE IC698RMX016-ED Redundant Memory Exchange Module
The IC698RMX016 is a Redundant Memory Exchange Module. It is part of the PACSystem RX7i platform, currently under Emerson Automation, formerly produced by GE Intelligent Platforms (GE IP). This module is mainly used in redundant CPU configuration or as reflective memory module that can be accessed over the network. It comes with 16MB SDRAM with operating voltage of +5VDC provided by the power supply and current requirement of 1.8 Amperes. This module is required to be mounted to the main rack and attach to slot 3 or 4. It comes with an Fiber optic LC type with Insertion loss of 0.35 dB (maximum) and Return loss of -30dB.
The IC698RMX016 is a Redundancy Memory Exchange Module (RMX) that is used with the PACSystem RX7i Programmable Automation Controller Series. This module mainly functions as a node on the reflective memory or as memory link between partner Central Processing Unit (CPU) modules that form a redundant pair in high critical applications. This module is mounted to the main rack of an RX7i backplane, recommended to be installed in Rack 3 or 4 to enable interrupt priority however, other slots in the main rack are also supported by this module.
The IC698RMX016 comes with 16 MB Static Dynamic Random Access Memory (SDRAM). This module is powered by the 5 VDC voltage, 1.8 Amperes that is sourced from the backplane. This module measures 6.299” (W) x 9.187” (H). Available connector to the Redundancy Memory Exchange Module is an LC Type Fiber Connector that conforms to IEC 61754-20. Connector material is Zirconium Ceramic Ferrule with maximum insertion loss of 0.35 DB and return loss of -30 DB. This module has operating temperature range of -20 Degree Celsius to 85 Degree Celsius.
During power up, the module has an unconfigured state. The IC698RMX016 operates until the host RX7i CPU module has sent the appropriate hardware configuration to the module. For general purpose reflective operation, the hardware configuration can be configured with a variety of parameters such as Node ID, Redundant Transfer Mode, Rogue Master, Network Memory Offset, and Interrupt enable however, in redundant operation, the mentioned parameters are automatically set by the CPU and cannot be configured.
