Hello,

I have system on site where there are we have 4 Mobile panels 277 which can be conected to 6AV6671-5AE10-0AX0 and can be dinamically conected/disonected. They can be conected at the same time as in theory they should have diffrent DP adresses.But we found out that it is sometimes happening that 2 HMI have the same DP addressess. Is it any easy way determining which DP adress is active using code  ? I attached screenshot of profibus topology for better understanding.

I am curently looking in the code but I will apreciate any help with this
