Hi,

can somone give me idea how can i controls Powerflex 755 with S7-1500.

mounted on Powerflex 755 the card 20-750-PNET2P, used for the profinet communication.

On TIA-Projekt iam using the GSD: GSDML-V2.34-RA-20-750-PNET2P-20220407.xml

in the HWKonfig there is an error.

an unmanaged switch FL SWITCH 1000  (phonic contact) is used.

there is no communication between Powerflex and CPU. the communication is only for shorttime and  then powerflex is not reachable.

thanks in advance
