Hello kkalu;
No, ComProfibus is only used to configure Profibus slaves, and import them to the Profibus Master (the TI555 in this case). ProTool/Pro is not a Profibus slave; it is a Master class 2; as such, there is no Profibus configuration to be done.
As I said before, Profibus connection is established through the PLC section of the ProTool project.
Hope this helps,
Daniel Chartier
