I am designing a 300m two wire Modbus RTU network with a PLC master. I will try to daisy chain my slave devices (29 devices) but require several taps off my trunk line. How long can these taps be? I have read information saying they must be less than 1m and I have also read that the taps cannot be more than 20m in length. Please confirm.
Also..does having passive taps reduce the overall trunk length?
Thanks
