Description
Product 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.
