IC698RMX016 冗余内存交换模块 反射式内存网络

【产品详情】

GE Fanuc 的 IC698RMX016是用于 Rx16I Pacsystem 的 7MB 冗余内存交换。它具有以下尺寸：6.299 英寸宽 x 9.187 英寸高。它具有 16MB 的 SDRAM 用户内存。电源的工作电压为+5 V DC。当前要求为1.8A。该装置具有符合 IEC 61754-20 标准的 f iber 光学 LC 型连接器和 zirconium 陶瓷套圈。最大插入损耗为0.35 dB，回波损耗为-30dB。可接受的温度范围在-20°C至+85°C之间。要完成安装，您需要确保具备以下所有条件：具有 7.2 或更高版本固件的 PACSystems RX00i CPU; 带电源的 PACSystems Rx7i CPU 机架;一台与 PC 兼容的计算机，带有 CIMPLICITY Machine Edition – Logic Developer PLC，4.5 或更高版本的编程软件以及必要的电缆。

请注意，为了满足辐射发射标准，包含多个 Memory Xchange 模块的 RX7i 系统必须安装在管道金属外壳或等效外壳中。内存模块 只能安装在 RX7i 机架 0（主）中。 建议将 RMX 模块安装在主机架的插槽 4 和 3 中。这为 RMX 模块提供了 VME 中断请求优先级。尽管建议进行此类配置，但并不严格要求将 RMX 模块放置在插槽 4 和 3 中。要安装 IC698RMX016 Redundant Memory Xchange，请确保机架电源已关闭。接下来，将模块滑入系统中为其配置的确切插槽。继续将电路板按入到位，不要强迫它。拧紧面板顶部和底部螺钉。接下来，确保将电缆连接到 RX 和 TX 连接器。光纤电缆应从 TX 连接器布线到下一个节点的 RX 连接器。将该板的 TX 电缆连接到下一个节点的 RX 连接器。重复上述步骤，直到环中的最后一个节点的 TX 路由到第一个节点的 RX 连接器。打开电源。

IC698RMX016最初在未配置状态下上电，此时其光发射器被禁用。在 RX7i CPU 向冗余内存交换模块发送硬件配置之前，该模块将不会在网络上运行。为了实现反射内存操作， 用户可以选择配置以下参数：冗余传输模式、节点 ID、网络内存偏移、恶意主站和中断启用。请注意，如果选择了冗余链路操作，则上述参数将由 CPU 设置，因此不可配置。请注意，IC698RMX016用作具有通用用途的反射式存储器模块，超出基本读写操作的附加功能，包括读取中断状态、使能中断、读取奇偶校验错误和使能奇偶校验，可由用户逻辑执行。

客户问答

问题：什么是IC698RMX016？答：IC698RMX016是GE Fanuc RX7i系列的冗余内存Xchange模块。

问题：IC698RMX016提供什么？答：该模块可作为反射式内存网络上的节点运行，或作为冗余 RX7i 系统中 CPU 之间的专用链路运行。

问：什么是反射式存储器技术/反射式存储器网络？ 答：反射式内存网络最多可以包含 256 个节点。每个节点都可以是与 5565 系列兼容的任何反射式存储设备。因此，当数据写入 1 个节点时，网络上的所有节点都会自动更新新数据。

问：反射式存储器网络中的节点是如何连接的？ 答：每个节点都使用光纤电缆以菊花链环路连接。第一个节点的发射器与第二个节点的接收器相连。第二个节点的发送器与第三个节点的接收器相连，依此类推，直到环路在第一个节点的接收器处完成。

问：当用作节点时，IC698RMX016有什么作用？ 答：当用作反射式存储器网络上的节点时，RMX 模块可在高速光纤网络上的 PLC 和其他计算设备之间提供确定性的数据共享。

问：不使用时，IC698RMX016与哪个模块在功能上相同？ 答：IC698CMX016。

【英文介绍】

GE Fanuc's IC698RMX016 is a 7MB redundant memory swap for the Rx16I Pacsystem. It has the following dimensions: 6.299 inches wide x 9.187 inches high. It has 16MB of SDRAM user memory. The power supply operates at +5 V DC. The current requirement is 1.8A. The device has iber optical LC connectors and zirconium ceramic ferrules according to IEC 61754-20. The maximum insertion loss is 0.35 dB and return loss is -30dB. Acceptable temperatures range from -20°C to +85°C. To complete the installation, you need to ensure that you have all of the following: a PACSystems RX00i CPU with firmware version 7.2 or higher; PACSystems Rx7i CPU rack with power supply; A PC-compatible computer with CIMPLICITY Machine Edition - Logic Developer PLC, programming software 4.5 or later, and the necessary cables.

Note that in order to meet radiation emission standards, RX7i systems containing multiple Memory Xchange modules must be installed in a pipe metal housing or equivalent housing. Memory modules can only be installed in RX7i rack 0 (main). It is recommended that the RMX module be installed in slots 4 and 3 of the chassis. This gives the RMX module a VME interrupt request priority. While such a configuration is recommended, it is not strictly required that RMX modules be placed in slots 4 and 3. To install IC698RMX016 Redundant Memory Xchange, ensure that the rack is powered off. Next, slide the module into the exact slot configured for it in the system. Continue to press the board into place without forcing it. Tighten the top and bottom screws of the panel. Next, make sure to connect the cables to the RX and TX connectors. The fiber optic cable should be routed from the TX connector to the RX connector of the next node. Connect the board's TX cable to the RX connector on the next node. Repeat the above steps until the TX of the last node in the ring is routed to the RX connector of the first node. Turn on the power.

The IC698RMX016 is initially powered on in an unconfigured state, at which point its optical emitter is disabled. The redundant memory switch module will not run on the network until the RX7i CPU sends the hardware configuration to the module. To enable reflective memory operations, the user can choose to configure the following parameters: redundant transport mode, node ID, network memory offset, malicious master, and interrupt enable. Note that if redundant link operation is selected, the above parameters are set by the CPU and therefore cannot be configured. Please note that the IC698RMX016 is used as a reflective memory module with general purpose, additional functions beyond basic read and write operations, including reading interrupt states, enabling interrupts, reading parity errors, and enabling parity, can be performed by user logic.

Customer question and answer

Question: What is IC698RMX016? A: IC698RMX016 is a redundant memory Xchange module of GE Fanuc RX7i series.

Question: What does IC698RMX016 provide? A: The module can operate as a node on a reflective memory network or as a dedicated link between cpus in a redundant RX7i system.

Q: What is reflective memory technology/Reflective memory network? A: A reflective memory network can contain up to 256 nodes. Each node can be any reflective storage device compatible with the 5565 series. Therefore, when data is written to 1 node, all nodes on the network are automatically updated with the new data.

Q: How are the nodes in a reflective memory network connected? A: Each node is connected by a Daisy chain link using a fiber optic cable. The transmitter on the first node is connected to the receiver on the second node. The transmitter of the second node is connected to the receiver of the third node, and so on until the loop is complete at the receiver of the first node.

Q: What does IC698RMX016 do when used as a node? A: When used as a node on a reflective memory network, RMX modules provide deterministic data sharing between PLCS and other computing devices on a high-speed fiber optic network.

Q: Which module is functionally identical to IC698RMX016 when not in use? Answer: IC698CMX016.
