Hello. I am working on a program and wanted to try to use explicit messaging to retrieve and write parameters to a PowerFlex70 drive with a 20-COMM-D adapter.I cant understand in which register i must write Pflex parameters. For example, how can i read and write frequency to a drive or something like this. I use Beckhoff "TwinCAT" software and PC Fieldbus card FC5201 for DeviceNet. I'm begginer on DeviceNet, so maybe can help me. Thanks.
