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°CTo 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.

Reflective Memory -- PC RFM to PACSystems RMX

Description

There is one red LED ON at the PC RFM card, but no communications with the PLC IC698RMX016 or IC695RMX128 modules.

After installing the Reflective Memory module and necessary optical cables, the PLC RMX module may still not be communicating with the PC RFM card.

Resolution

The PLC Reflective Memory Module (RMX016 and RMX128) can be configured as a Redundancy Only Link, or a Communications Only Link. They can not function as both at the same time.

There needs to be a slight change to the PLC RMX Module default configuration:

- Open the project in Proficy Machine Edition
- Go to HW configuration
- Locate RMX016 or RMX128 module
- Double-click to open its properties
- Locate "redundant link" entry
- Change this to "Disabled" to allow external communications
- Download the HW configuration to the PLC

The RMX module should now be working as an "ordinary" CMX module, which will now communicate with the RFM card in the PC.

Note that you should purchase a CMX card for PLC communications, as the RMX is designed to support PLC CPU redundancy. However it may be used as described above where CMX stock is not available or to maintain 1 part number for interchangeable spares.

 

 Customer Questions and Answers


  • Question:  What is an IC698RMX016?  Answer:  The IC698RMX016 is a Redundancy Memory Xchange module from the GE Fanuc RX7i Series. 
  • Question:  What does IC698RMX016 provide?  Answer:  This module operates as a node on a reflective memory network or as a dedicated link between CPUs in a redundant RX7i system. 
  • Question:  What is reflective memory technology/a reflective memory network?  Answer:  A reflective memory network can contain up to 256 nodes. Each node can be any reflective memory device that is compatible with the 5565 family. So, when data is written to 1 node, all nodes on the network are automatically updated with the new data. 
  • Question:  How are the nodes in a reflective memory network connected?  Answer:  Each node is connected in a daisy-chained loop using fiber optic cables. The transmitter of the first node is tied to the receiver of the second. The transmitter of the second node is tied to the receiver of the third, and so on, until the loop is completed back at the receiver of the first node. 
  • Question:  When used as a node, what does the IC698RMX016 do?  Answer:  When used as a node on a reflective memory network, the RMX module provides deterministic sharing of data among PLCs and other computing devices on a high-speed fiber optic network. 
  • Question:  When not in use, to which module is the IC698RMX016 functionally identical?  Answer:  IC698CMX016.
  • Question:  What should I do if my IC698RMX016 is not working properly?  Answer:  Your IC698RMX016 may need repair.
