4.1.3 PROFIBUS terminator (active RS485 terminator)

What is a PROFIBUS terminator?

The PROFIBUS terminator provides active termination for the bus. The main advantage of

this is that bus nodes can be switched off, removed or replaced without impacting data

transfer. This applies in particular to the nodes at both ends of the bus cable on which the

terminating resistors normally have to activated and supplied with power. The PROFIBUS

terminator can be installed on a standard rail.
