Please also see the attached screenshots. I am not sure if this is a HW or SW problem. We have a temperature measurement (a PT100 sensor connected to PIW1408) that gives us alarms when it shouldn't. At the moment the sensor (a new sensor) is connected with a short cable directly to the terminals in the cabinet so it is very unlikely that the fault is on the sensor or cable. You can see the green line of the trend curve that it is still coming with irregular intervals. It is almost always there for 5 minutes and then is gone and comes back again later. What can cause this and what is the best way of troubleshooting it? AttachmentFD1 AA#016 A.zip (689 Downloads) |
