Instead of correcting these issues at the level of the device, the Controller may find it easier and more efficient to make changes to the calculation results themselves. You can give your Controller permissions to make changes to the data.

If you allow the Controller to make changes to the history, they are able to make changes to the following values on the Pipeline Monitor (PLM) History window in easy eXtended Operator Station (ezXOS):

  • Deviation values for the Current, Monday to Sunday, and Monthly

  • Meter In values for the Current, Monday to Sunday, and Monthly

  • Meter Out for the Current, Monday to Sunday, and Monthly

  • Delta Linepack for the Current, Monday to Sunday, and Monthly

  • Tanks for the for the Current, Monday to Sunday, and Monthly
