The active RS 485 terminating resistor is used to terminate bus segments. The resistor is supplied with power independently of the bus nodes. The terminating resistor is hereby supplied separately from the other I/O components with a permanent voltage or with a voltage switched upstream of the I/O. By terminating the bus system, the nodes (e.g. ET 200SP) can be freely connected and disconnected without malfunctions.
