F650-N-F-L-F-2-G-1-HI-P-6E的后部最多可增加兩個(gè)通信卡。除了兩個(gè)相同的端口COM1和COM2外，板卡還可以包含一個(gè)用于連接遠(yuǎn)程CAN總線I/O模塊（CIO模塊）的CAN總線通信端口。當(dāng)繼電器內(nèi)部可用的最大I/O數(shù)量（最多64個(gè)輸入和16個(gè)輸出）不足以滿足特定應(yīng)用的需求時(shí)，使用CIO模塊將F650-N-F-L-F-2-G-1-HI-P-6E的I/O數(shù)量增加一倍。除了增加I/O數(shù)量外，CIO模塊還允許F650-N-F-L-F-2-G-1-HI-P-6E監(jiān)控位于遠(yuǎn)程位置的信號，兩個(gè)設(shè)備之間只有一個(gè)連接，從而顯著節(jié)省了安裝成本。
遠(yuǎn)程I/O功能提供了一種在F650-N-F-L-F-2-G-1-HI-P-6E或其他符合IEC61850的IED或控制器之間共享數(shù)字點(diǎn)狀態(tài)信息的方式。遠(yuǎn)程輸出通過IEC 61850 GSSE消息與其他F650設(shè)備的遠(yuǎn)程輸入無縫對接。用戶安全的對等通信，以開發(fā)分布式邏輯和I/O中的復(fù)雜方案。

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.
