I made below a scribbled plan to my system.
The 2 right mppt's on ve.direct and the pylontech batteries with their bms connected om ve.can were working for some time without problems. Pylontech bms connected to ve.can was installed without any terminators, either on gx or the battery and it worked fine.
However, needs arrised for a 3'rd mppt. I can t connect it on ve.direct, since i have only 2 ports. Simple connection on the free ve.can port did nothing, so i figured out i need terminators. But where should i put them? On mppt only, or on mppt and on the pylontech battery? Wich one, first, or last?
