When the state is "Foat", the charger is very small. When the state is “External control”,the charger power is high. I don't understand why the state is changed every some seconds ?

If it is communication problem ? But there is no alarm on GX touch panel.

You need to see if the entry on the GX is disappearing, it won't generate an alarm. Might be a bad cable. Make sure you aren't using both a cable and smart networking, these can conflict and aren't intended to be used together.

Thanks very much, I find the reason. I run a new VE.DIRECT cable, now it is OK.

I see something similar on my configuration. The drops on my case are just clouds. Looks the same.
