Hi, In the https://support.industry.siemens.com/cs/us/en/view/19539653 manual you can read under chapter "5.16 Diagnostics of the Analog Modules" : You obtain programmable diagnostic messages only if you have enabled diagnostics by parameter assignment. You perform parameter assignment in the “Diagnostics” parameter block in STEP 7(refer to Section 5.7). Also you can read there: Every analog input module supplies the measured value 7FFFH irrespective of the parameter assignment when an error is detected. This measured value means either Overflow, Malfunction or a channel is disabled You read -32767 what makes 8001H so... that is an other case. The card settings and configuration unknown so I can not tell you more from here, but I hope I could give a good start! |
