All AI shown Bad PV at driver block, even the reading is correct. I already toggle the ACC_MODE, but it seems not help. Please advise ------------------------------------------------------------------------------------------ Split from AI Quality code error. Attachment HMI 2.JPG (318 Downloads)

The input of the Mode is 16#40...... this means the value it gets at the PV_In is invalid. The input of the Mode should be 16#80.... For more details have a look at the manual PCS 7 Advanced Process Library (V9.1 SP2) at the section Mode Settings for SM Modules. With regards Heisenberg
