I'm trying to develop a software which should read tags from a Simatic S7-314 / CP 345-2. For this I'm using S7.NET + c#.
I'm using a IBHLink S7++ gateway between the profibus and ethernet networks. If I'm using the MPI interface of the CPU, everything runs as expected. But If I'm connecting to the profibus interface from the CP 345-2, I cannot read anything from the PLC DB.
Any ideas what could cause the problem?
Thank you,
Alex
