GE Fanuc IC698RMX016 Module

GE Fanuc IC698RMX016 New

Description

The GE Fanuc’s IC698RMX016 is a 16MB Redundant Memory Xchange for the Rx7I Pacsystem.  It has the following sizing: 6.299 inches widde x 9.187 inches high. It has 16MB of SDRAM user memory. The operating voltage from power supply is +5 V DC. Current requirements are 1.8A. The unit has a fiber optic LC type connector which, conforms to IEC 61754-20, and a zirconium ceramic ferrule. The maximum insertion loss is 0.35 dB with a return loss of -30dB. An acceptable temperature range is between -20°C and +85°C. To complete installation, you need to make sure you have all of the following: A PACSystems RX7i CPU with release 2.00 or later firmware; a PACSystems Rx7i CPU rack with power supply; a PC-compatible computer with CIMPLICITY Machine Edition – Logic Developer PLC, version 4.5 or later programming software and the necessary cables.

Note that in order to meet radiated emission standards, RX7i systems that include more than one Memory Xchange modules have to be installed in a conducting metal enclosure, or equivalent. Memory modules should only be installed in RX7i Rack 0 (main). It is advised that RMX modules are installed in slots 4 and 3 of the main rack. This provides the RMX modules VME interrupt request priority. Although such configuration is advisable, locating RMX modules in slots 4 and 3 is not strictly required. To install IC698RMX016 Redundant Memory Xchange, make sure the rack power is switched off. Next slide the module into the exact slot it was configured for in the system. Proceed to press the board in place without forcing it. Tighten faceplate top and bottom screws. Next make sure to connect cables to RX and TX connectors. The fiber optic cable should be routed from the TX connector to next node’s RX connector. Connect the that board’s TX cable to next node’s RX connector. Repeat until last node in the ring has its TX routed to the RX connector of the first node. Turn the power on.

The IC698RMX016 initially powers in a non-configured state where its optical transmitter is disabled. The Redundant Memory Xchange module will not operate on a network before the RX7i CPU sends the module a hardware configuration.  For the purpose of reflective memory operation, the user can choose to configure the following parameters: Redundant Transfer Mode, Node ID, Network Memory Offset, Rogue Master, and Interrupt enable. Note that if the Redundant Link operation is selected, the above-mentioned parameters will be set by the CPU and are therefore not configurable.  Note that when IC698RMX016 is used as a reflective memory module with a general purpose, additional functions that extend beyond the basic read and write operations, inclusive of reading interrupt status, enabling interrupts, reading parity errors, and enabling parity may be performed by user logic.
