This videos describes what to do when you receive a parameter error on a Mitsubishi Electric Q Series system that relates to conflicts in a multiple CPU system. This multiple CPU error is typically error code 3012 or 3015 and can be cleared by copying settings from one controller and importing them into the other CPU, or by carefully examining the multiple CPU settings in each controller to make sure they match. This requires the programming software packages from Mitsubishi: GX Developer or GX Works, and/or MT Developer or MT Works2.
