Interface with thermoregulator Eurotherm 3504

Hello,

I ask your help to solve a communication problem between a CPU 315-2 DP (master of the DP net) and two thermoregulator units Eurotherm 3504.

The Profibus network has this structure :

CPU315-2 DP : Master of the net (theCPU is in MPI Net with another CPU 314C/2Ptp).

ET200M : Slave, with address 3. The ET200M has 1 8AI card (6ES7331, acquiring 8

Thermocouples).

Eurotherm 3504 #1 : Slave, Address 11.

Eurotherm 3504 #2 : Slave, Address 12.

The DP net works correctly only with ET200M (I read correctly the temperatures detected from the thermocouple).
When I wire the thermoregulators (one or two, it doesn't matter, the CPU detect a status fault. They're wired as 2nd and last component of the the slave net (in the samo order of the HW configuration). I believe that the problem is in the GSD file but I don't understand where.

I enclose a zip file containing the S7 project (it is without PLC software because we're testing the network, the gsd file and the thermoregulator configuration) and the gsd files of the Eurotherm 3504

Can you help me to solve this problem ?

Thanks in advance
