Checking for Bad Tag(s) in Formula Builder

I used Formula Builder to create a calculation that is the Max of six (6) temperature tags to derive the peak temperature for monitoring.Is there a function or method that I can use to filter out tags that are reported with a Bad status by the source data historian system?As it stands, my peak temperature calculation stopped updating because one of the 6 tags is Bad in the Aspentech IP.21 data source

Context Field Formatting

I configured Context Fields that are mapped to calculations associated to a value-based search . Once I search, then select results to create context items and map my calculations, I can see the fields in a Context Hub view.The Context fields I created get mapped to calculations that represent peak temperatures in the range of 1200 to 1400 ‘F. On the Context Hub view, I see results for my context fields with 3 or more decimal places and that is unnecessary. How can I format the values tied to the context fields / value-based search calculations to use 0 decimal places?

Monitor using Value-Based Search with Context Fields

I configured a value-based search and added calculations to the search. I created context items based on the search results and assigned a context type with associated context fields mapping to the value-based search calculations. Question is: if I configure a monitor using that value-based search and get the monitor to create context items with this specific context type , I see the context fields being listed with optional drop-down boxes. What do I do with these? Will the context item automatically fill-in the results of the calculations to the context fields?

Sharing to all users?

How to share a datasource to all users? I can't really find a good way to do that.We have an SSO-integration setup towards (A)AD, but have little control over that. Not sure if i could use the local identity provider and create a group that includes all (domain and/or local ) users.

Event Counter on Custom Calculations

Hi,  I have been trying to set up an event counter using custom calculations, but the values coming up are not the correct ones and they do not match with the context item I have also created. Any tips of where I could be going wrong?  The event counter for the custom calc (in blue) and clearly starts before the event of the tag (>0.02) is happening.   I appreciate any inputs you can give me.

Identifying & contextualizing anomalies based on duration

After doing a cleaning of one equipment, in an aseptic system, it requires to flush it with steam to sterilize it for 10 minutes, if the time is higher than 10 minutes, then that time (the differential) is considered as an anomaly or waste of energy. If I create a Value Based Search it detects all the events with highest duration of 10 minutes, but I can’t consider the whole time detected, to be considered as a waste it has to last more than 10 minutes, therefore the time detected requires a subtraction of 10 minutes in the duration. Is there any function in a formula to create a conditional based in time duration to create a soft-sensor, something like if Sterilization step > 10 minutes then 1, otherwise, 0

Where can i find a list of demo tags?

I could not find a list of the tags in the demo datasource in the documentation, nor a description of what data is in these tags over what time period. Is that available in some way? And these tags are available to all users, right? Reason to ask is to build localized training materials that are not dependent on user's permissions to ‘real’ tags

Golden Batch Master Mind Group

Hello,what do you think about setting up a master mind group for the Golden Batch topic? My first idea is a peer-to-peer mentoring group where we can exchange about all topics around golden batch and share our experiences for all experience levels. Looking forward to hearing from you. BestSören

Downtime Dashboard

I was able to follow the instructions on another thread on how to create an aggregation tag for an integration over 24 hours of a binary tag for line running or not and it will give me the downtime over the last 24 hours at any specific point. Is there a way to lock in a time so that on any given day at 7 am, it will show me the downtime over the last 24 hours to the previous day at 7 am? We have a few metrics like that that we report out on over the 7 am - 7 am window and that feature would be very helpful.

Insights about dashboard usage

Hey TrendMiner Team,we are looking for a way to check the usage of our dashboards. We would like to know which are the most frequently used dashboards and how many different users are using the dashboards daily, weekly or monthly. We are not looking for the usage of individual individual users but rather for an usage overview so that we can check adoption of the dashboards and see whether we need to push some dashboards more to our users. I am wondering which options we have to analyse the usage. Ideally, we would be able to do this ourselves within the software (ConfigHub). Best wishesSören

Fingerprints Duplicating or giving opposite results

I have a system with 2 fingerprint monitors active. The fingerprints are copies of each other, and one monitor checks for matches while the other checks for deviations. They have the same detection threshold. Frequently, the “match” fingerprint gives 2 match alerts (I have the monitors generate context items) a ~2 minutes apart for the same event. The length of the fingerprint is ~30 minutes and there are 3 tags involved. Other times, the “match” fingerprint and the “deviation” fingerprint will both detect and give conflicting context items. How far apart do the detection thresholds need to be to avoid this (ie can it be 84 and 85% or does it need to be more like 80 & 85%)

Time shift calculation

I am interested to know which product is being produced in chemical reactor in series… I know the current product at the exit of production, but not which product is being run in each reactor. I know the residence time in the different reactors. Is there any possibility to create a formula indicating which product is being produced in each reactor by applying a variable time shift which depends on the residence time?

Tags Indexing/Re-Indexing (or update)

I have  a connection to a PI system that includes, amongst other things, lab data (originating from LIMS) and PI-AF calculations. I have a PI-AF calculation that is making use of a lab tag. This week, an invalid entry was made in LIMS for the lab tag and the value was subsequently substituted/updated in PI. I recalculated/backfilled the associated PI-AF calculation and trends of both the lab and PI-AF calculation is correct/accurate in PI. The configuration of the lab tag was also  modified to force the step attribute to 1, so that values appear in a staircase format in PI.I would like these changes to be reflected in Trendminer, so I tried refreshing the index for both the lab tag and the calculation and that did not appear to do the job. Incorrect values that had been recalculated in PI are still showing in Trendminer. And the lab tag still is not represented in staircase format.What am I missing?
