CI 868 Performance -Max.Number of Control Commands Question

Hello,

in the all the manuals refering to CI868 Performance Data, it is stated that the Maximum Number of MMS Control Command send is 1 / sec (MMS Control Commands sent from CI868 via CSWI & XCBR LNs). The same is applied if it is GOOSE and MMS mixed.

Can it be that CI868 operates so slowly? Only one command per second? It is not possible to send commands to further IEDs at the same time?

It seems to be a very serious restriction for demanding applications where several loads should be switched within a critical time frame.

Could you please send your feedback and clarifications?

Thanks in advance.

If you are looking for time critical applications then there is GOOSE. CI868 can send 10 changing signals/seconds via GOOSE.

MMS is for slow applications, its not real time. It will be hard to imagine a plant where more than one CB is open every second.

CI868 is mainly designed for horizontal communication.
