Hi Support,
thanks for your suggestion.
Yes, my Xpander2 has RS232 port for PLC's to talk to it. But since T100MD888+ has only 1 RS232 port, it is possible or nothing wrong on the connection, if I will provide splitter for RS232, so more PLC's could shared (like Xpander2, Xserver, etc.) from T100MD888+?.
