I have a blending plant based on the Honeywell IPC620-30 which is programmmed with IPC620-60 software resident on the old HP Vectra ES15. However I lost the power supply to the PC and had to search for a week for a replacement. On restarting the HP and trying to go online I am getting an error saying: Command 4 - communications timeout. What should I do?
