Bad Quality Data

To help with troubleshooting we have replaced 0.00 data readings in the live views with ??? to indicate when there is a bad data reading.  A bad data reading could be any of the following. 

Kepware data quality = bad

  • the device is offline, then all tags receive a bad quality data
  • a tag with a formula field and the formula syntax is bad
  • a tag with a formula that is referencing a tag that has bad quality data
  • invalid i/o address at the tag level 

Gateway data quality = bad

  • the device is offline, then all tags receive a bad quality data
  • a tag with a formula field and the formula syntax is bad
  • for an entity with multiple gims and 1 gim goes offline then bad quality just for that gim 
  • invalid

Note:  To retrieve the last known good value the End User will need to preform trending.
