We checked voltages, p.supply, cable, teminator resistor,etc.
rslogix sees all vfds
16 devicenet vfds are all connected but only one can accepts commands.
We removed the devicenet module from one vfd to another and it works.
we are able to upload and download to each vfd separately
we dont know why the other vfd cannot respond to commands like run and stop
if you have suffered similar issue or experience your advice to trouble shoot would be very appreciated!
thanks!
