I have to communicate to Parker Compax3 drive containing profibus dp protocol from my PC .If i have selected PCI Profibus card is it possible to communicate to drive.
I'm guessing the Parker drive is acting as slave on the network and the DF PROFI II is acting as master. Can you post screenshots of where you see the errors?
Also, were you able to correctly download the network configuration via Configurator III to the DF PROFI II? My initial suspicion is something with the configuration.
