The other week one of our panel view 1000s was thought to have crashed. We did not have a PV1000 color in stock so we used a PV1000 monochrone. This PV had a DH+ comm board, we needed a control net. So I removed the control net from the thought to be bad PV and put it in to the replacement PV. When we tried to download the PB32 prog into the replacement PV we kept getting errors. This is the first time I really dealt with PVs on this scale, is it possible to download a program from a PV color to a PV grayscale? I know the color feature and some graphics would be eliminated but in principal is this possible? If so what could I have been doing wrong?
