G6450081A KJ2003X1-BB1工控卡件■ 动态数据包大小为4到64字节，由内存交换模块控制。■ 最大网络传输速率为43兆字节/秒（4字节数据包）到174兆字节/秒（64字节数据包）■ 可编程VMEbus中断输出。*■ 四个通用网络中断，每个中断有32位数据。*■ 网络错误检测。■ 每个网络最多256个节点。*■ 冗余传输模式操作。此可选模式降低了数据包被从网络中删除。*■ 可配置的网络内存偏移允许您根据他们使用的网络地址空间中的16MB段。**在CPU冗余系统中作为冗余链路运行时不可用。更新具有BA和更早版本的IC698RMX016模块必须返回制造厂进行替换网络带宽反射内存网络的最大带宽为174MB/s。应用程序必须避免传输FIFO满的情况。您可以通过不使用多个节点来实现这一点同时传输大量数据。可以监测LISR（区域2，偏移10h）的RX FIFO几乎完全状态（位09），以确定是否网络正在变得饱和。有关网络负载平衡的示例，请参阅PACSystems RX7i中的“优化网络带宽”内存交换模块用户手册，GFK-2300。

Features 

■ PACSystems RX7i single slot form factor. 

■ 16 Mbytes reflective memory with parity.* 

■ Software configuration of all node parameters (no jumper or switch settings required).* 

■ High-speed easy-to-use 2.12 Gbaud fiber-optic network. 

■ No RX7i CPU processing required to operate the network. 

■ Network-compatible with VMIC 5565 family of reflective memory devices. 

■ Connection with multimode fiber up to 300m /984.25ft. 

■ Dynamic packet sizes of 4 to 64 bytes, controlled by the Memory Xchange module. 

■ Maximum network transfer rate of 43 Mbyte/s (4 byte packets) to 174 Mbyte/s (64 byte packets) 

■ Programmable VMEbus interrupt output.* 

■ Four general purpose network interrupts with 32 bits of data each.* 

■ Network error detection. 

■ Up to 256 nodes per network.* 

■ Redundant transfer mode operation. This optional mode reduces the chance of a data packet being 

dropped from the network.* 

■ Configurable network memory offset allows you to assign nodes on a network to groups according to the 

16MB segment in the network address space that they use.* 

*Not available when operating as a redundancy link in a CPU redundancy system.Updates 

IC698RMX016 Modules with versions -BA and earlier must be returned to the manufacturing facility for 

replacement. 

Network Bandwidth 

The maximum bandwidth of the reflective memory network is 174Mbytes/s. The application must avoid a 

situation where the transmit FIFO becomes full. You can accomplish this by not having multiple nodes 

transmit a large amount of data at the same time. 

The RX FIFO Almost Full status (bit 09) of the LISR (Region 2, offset 10h) can be monitored to determine if 

the network is becoming saturated. 

For an example of network load balancing, refer to “Optimizing Network Bandwidth” in the PACSystems RX7i
