Hi,
Is it possible to brick an EX-RC1 during a ladder download? I am just learning Visilogic and do not have much experience with PLC's, so I make little adjustments to my ladder then download it to see the results. My current setup is a Vision 280 (ID#1), the EX-RC1 (ID#2) connected via CANbus, and an IO-ATC8 set up for thermocouples. I have downloaded to both units several times so I know my connection are correct. When I encountered the problem I had changed the STRUCT(collect) in the IN module to MI's for the analog inputs. I seem to have done it incorrectly because the download did not even finish and communication was lost. I can connect the programming cable to the V280 and it talks fine so it is definitely the EX-RC1. If I go to Connections->Communication & OS and hit 'Get OPLC Information' it times out and gives 'Communication Driver Error (206)'.
I would have expected an error of some sort, but to kill it seems pretty extreme.
