Can i terminate(put resistor in terminal of channel a)the blue hose of an existing plc5 dh+ network to a new 1756-dhrio in new clx rack without changing the plc5 code or do i have to define it in io of plc5? So from node 1-27, node1 being the plc5 scanner, the new will be 1-20+node 30,node of dhrio, both in 115k baud rate.
