I am working on a program and wanted to try to use explicit messaging to retrieve and write parameters to a PowerFlex drive with a 20-COMM-D adapter instead of being limited to the Datalinks. I have studied Allen Bradley's examples and and some others I have but they are vague in answering questions that I have.
We are using a SLC processor. My questions are: It looks like you can read more than one parameter per transaction but the book doesn't go into much detail on how to do this. Is this possible and can they be random? The book only shows two rungs of logic, are these all that are needed for read and writes or do you need a set for each? The example program I have was for a DeviceNet panelview and several inverters and correct me if I'm wrong but it appears that you can send info directly to the inverters from the panelview without going throught the PLC prgram. My panelview is not DeviceNet so I had some trouble comparing the two. Does anyone have a good example prgram for this type of application?
Thanks,
Larry
