I'm trying to make KR C2 and a Mitsubishi PLC talk over Profinet. These two were happily married, but then the PLC software had to be changed. The owner did not have source code, and the previous company who did maintenance lost all the files, so I had to work with what I could read from the PLC.
Problem is, after downloading new PLC program, the Profinet communication stopped. It had worked previously, I am sure of that. I've checked Inputs and Outputs on KCP and they transferred correctly back and forth with PLC.
I think maybe the problem is because GSD file was not stored in the PLC, so when I uploaded project fro PLC, the PN configuration was blank. When I downloaded a new program, it got a blank config, and thus the comms stopped.
I've read manuals from here, that didn't help much because it was for configuring a Siemens PLC, not Mitsubishi.
I've tried using GSD files from here. When I import them, Mitsubishi Profinet Configuration tool takes the files, but when I configure the PLC PN module and go online, there is no communication.
I can ping both the PLC and CP1616 card. Activity lights on the LAN switch are blinking furiously. CP1616 is already configured, so I think the problem must be in the PLC.
PLC CPU is R04EN, Profinet comms module is RJ71PN92. Kuka controller is KR C2 + CP1616 PN card. PLC and Kuka were exchanging 16 inputs and 16 outputs, all binary, no analog.
Where to go from here? Are the generic GSDML files for CP1616 not suitable here, or I'm configuring them wrong?
Is there a possibility that there is a GSDML file stored somewhere on the KR C2 hard drive?
Thank you all very much!
