Posted 5 Dec 2005 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. Share this post Link to post Share on other sites
Posted 15 Dec 2005 I have setup and used many DeviceNET slaves with TwinCAT, but not a PowerFlex. If you are only using polled data it is very straight forward. Add a DeviceNET node into System Manager using the EDS file, then link variables to the IO in the program. Changing the parameters is usually a bit more involved, but I seen to remember there may be a funtion block in the TwinCAT library to ease the pain. Share this post Link to post Share on other sites
