  1. I'm in the same situation Mike. I don't see anyway around this if you try to use the exponentialFilter function. The error is because .toScalars() returns a Group of Scalars, not a single scalar. I got around that by calling average() on the Group:Scalar, still to no avail, the function still wants it to be a constant.
  2. We have similar issues with some tags. In our case, the tags are already Step tags but still have gaps that are smaller then the max interpolation setting. In this case, we use $signal.validValues formula to achieve exactly what you've described.
  3. Bharat, Depending on how you're assets are organized in AF, you may be able to use the TreeMap view. From the documentation, "Treemap is a monitoring tool that may be leveraged by those that use an asset tree structure, such as PI Asset Framework. Treemap compares a plant's similar assets and identifies when user specified conditions occur. This tool allows users to quickly gauge the performance of an asset relative to other, similar assets." We use this method to monitor for deviations between redundant flow meters on dozens of different assets. In our case, we developed two condi
  4. Include signal values for Start/End of each capsule in capsule summary. This may also take care of number 2 Include string signal values at Start/End of each capsule in capsule summary. Include capsule properties and values in Information tab
  5. I've faced similar issues. You may find it more accurate to take the opposite approach. If the error you are seeing is due to the totalization of all the decreases, you could instead totalize the increase and add that to the difference between the starting/ending amount. Example: Calculate amount used by subtracting the ending amount from the starting amount over whatever time span you'd like. Let's say it's daily and at the start you were at 1000lbs and the end you were at 500lbs plus you totalized an increase period (delivery) during that day of 250lbs. Your daily usage would then be (start
  6. I understand the uncertainty aspect, but showing a capsule which does have an end time as "In Progress" is not correct. Thank you for the information.
  7. I have successfully setup two (MS SQL) condition queries in the SQL Connector V2 JSON file. When I add these conditions to a trend, the last capsule shows "In Progress" in the Capsules table although the SQL does return an end date for this capsule. The capsule at the top of the trend does end at the correct time, but it is hollow as if the capsule is in progress. Any help on this would be appreciated, Andrew
