 Hello, 

Welcome in our forum. if I correctly understand your question, you mean by changing order changing position not address?

if yes there is no matter to change position of module, the essential not changing address.

Hello Terfasaj;

One important point should be added to Med_Selmi's point: the termination resistors st each end of the network should be set to "ON", all the others should be "OFF". 

So if you modify the location of the Profibus nodes in your project, you must make sure that in the end you take care of the termination correctly.

Hope this helps,
