F650-N-F-L-F-2-G-1-HI-P-6E 板卡还可以包含一个用于连接远程CAN总线I/O模块

F650-N-F-L-F-2-G-1-HI-P-6E的后部最多可增加两个通信卡。除了两个相同的端口COM1和COM2外，板卡还可以包含一个用于连接远程CAN总线I/O模块（CIO模块）的CAN总线通信端口。当继电器内部可用的最大I/O数量（最多64个输入和16个输出）不足以满足特定应用的需求时，使用CIO模块将F650-N-F-L-F-2-G-1-HI-P-6E的I/O数量增加一倍。除了增加I/O数量外，CIO模块还允许F650-N-F-L-F-2-G-1-HI-P-6E监控位于远程位置的信号，两个设备之间只有一个连接，从而显著节省了安装成本。
远程I/O功能提供了一种在F650-N-F-L-F-2-G-1-HI-P-6E或其他符合IEC61850的IED或控制器之间共享数字点状态信息的方式。远程输出通过IEC 61850 GSSE消息与其他F650设备的远程输入无缝对接。用户安全的对等通信，以开发分布式逻辑和I/O中的复杂方案。

Up to two communication cards can be added to the rear of the F650-N-F-L-F-2-G-1-HI-P-6E. In addition to the two identical ports COM1 and COM2, the board CAN also contain a CAN bus communication port for connecting to a remote CAN bus I/O module (CIO module). When the maximum number of I/ OS available inside the relay (up to 64 inputs and 16 outputs) is not enough to meet the needs of a specific application, use the CIO module to double the number of I/ OS of the F650-N-F-L-F-2-G-1-HI-P-6E. In addition to increasing the number of I/ OS, the CIO module also allows the F650-N-F-L-F-2-G-1-HI-P-6E to monitor signals located in remote locations with only one connection between the two devices, resulting in significant savings in installation costs.
The remote I/O capability provides a way to share digital point status information between F650-N-F-L-F-2-G-1-HI-P-6E or other IEC61850-compliant IEDs or controllers. Remote outputs Interface seamlessly with the remote inputs of other F650 devices via IEC 61850 GSSE messages. Secure peer-to-peer communication for users to develop complex schemes in distributed logic and I/O.
