Location of Anybus-X Gateway on a Profibus Network

[kdcui]

Hi,
I'm retrofitting an Anybus-X Gateway as a Profibus Master on an existing Profibus segment. I'm wondering if this needs to be the last device in the chain (with the Terminating Resistor ON) or if I can put this Gateway in the middle of the daisy-chain (with the Terminating Resistor OFF).

I was not sure if PB Masters expect to be the last device.

Thanks

You can put the X-Gateway anywhere you want on the network. The node address of it has to match the node address in the configuration of the Profibus master.

Great - Yes the master node address will match, just wasn't sure about the physical placement as I have not worked with a lot of Profibus networks before. I've always seen the Master (on PB and other impedance based networks) at the end of the daisy-chain hence the confusion.

Thank you

Profibus devices (master, slaves or repeaters) can be anywhere on the network, as long as the 2 ends of each segment are terminated.
