Hello, I would like to make a monthly average over a TAG. Since the maximum aggregation period is 1 day I would like to know how to make this calculation using another method. I already checked the topic How Can I Apply Stronger Aggregation for Long-Term? | TrendMiner Community but this does not answer as I need to save this calculation as a new TAG. Please let me know how to solve this. Thank you,Victor Nassau

I need help to set up a monitor and an automated e-mail when a tag goes bad.Not when the the tag goes to zero or any other defined value, but when it’s missing completely.

Hello,Is the score of a deviation in any way affected by the scale settings of a tag when saving the fingerprint? For example: We are saving fingerprints and are changing the range of the y-axis for visualisation reasons. Therefore, we would like to know whether these changes have an affect on the threshold for fingerprint deviation monitors. The documentation states:“Scores for similarity search results are based on visual similarities between the query (solid line) and the search result (dashed line). At every point the absolute difference is taken, summed, and rescaled to the range of the query time period. A relative score from 0% to 100% is obtained.” Hence, I am wondering whether the scale has an impact on the fingerprint deviation scores too. BestSören

Hello, I’m looking for a way to setup of formula to return value of tag A during certain condition based on value of another tag B. The goal is to check, if during specific phase (“phase” is when tag B is in the range of 1 and 10), the value of A tag exceeds the value captured during the start of the phase, for, let’s say, 5 points increase.I assume this all can be done setting up using formulas and monitoring, but the bottleneck currently is to capture the start value of the tag during the start of the phase and to reference to this value during the phase duration (and this logic should be happening with each new phase, indeed).Example for better understanding: tag B becomes 1, we need to capture the value of tag A at this moment (let’s say 3), and then during all the time when tag B is going the way from 1 to 10, we need to constantly check if the value of tag A is not increasing on more than 5 points (meaning, threshold for this specific phase would be 3 + 5 = 8); so if value of tag

I am doing a quality analysis for which I have created specific trends. Now whenever there is a new quality issue, I can use these trends to analyse the problem. However, since the issues occur on different times and dates I need to change the basis layer and the reference layer for correct comparison.  I created a dashboard with all the relevant information. The information is very simple. It shows multiple graphs of KPIs with a basis layer and a further reference layer for comparison. To save me some time, I was hoping that it is somehow possible to change the date and time of both layers for all of the trends at the same time. Is this possible and if yes, how?  

Good day, TrendMiner hive.Our IT department has approached me about optimizing our on-prem Azure storage allocation. It appears that our current setup may be over-provisioned for our actual usage.According to the online documentation for 2025.R2, the minimum storage requirements are listed as:SSD, 200GB + 300GB, 250MB/s.However, our current usage is significantly lower:OS: 21GB used out of 511GB provisioned Storage: 109GB used out of 600GB provisionedGiven this, IT is considering reducing the allocation to something more aligned with our needs—perhaps 64GB for OS and 200GB for Storage.Would such a configuration be sufficient for running and upgrading without issues?Any insights or recommendations about adjusted the storage footprint would be greatly appreciated.Thanks in advance!— Edward Burch

I created a calculated load of an adsorption bed via custom calculations.Unfortunately the value of the load resets every beginning of a new month. I guess that’s related to the index granularity.Is there any chance of continuing the values from the previous month?Best regardsSascha

Is there a way where you can calculate the total production of a certain product. What I mean is that you consume this certain product numerous times a year. But every time the totaliser gets reset and starts again at zero. I want a way where you can combine all the totalisers so you know how much you consumed during the whole year.Example:Product A: 0 to 10000Product A: 0 to 150000Product A: 0 to 20000End total 2025 Product A: 180000 kg 

Dear Team,Can we save the view with future dates let’s say 4 days future data and use this view in dashboard? Currently we are making live view which refresh and show up to current timestamp. what if we want to use this as current+4days?

Hi,  I am trying to set up a Custom Calculation to check if a variable is under many conditions, but I got stuck in a problem. The two limits (max and min) only get new data points in the data base when we change recipes. I tried to use .ffill() to fill the data base with the older values, but it did not work. I still get NaN results for the time I dont have values.   

Dear Team,We have value based search for tag. We want to do value base search and trigger alarm for future value as well. How it is possible?

Dear Team,How to set the frequency of email in monitoring tool?

I just found these tags in TM: TM_hour_UTC, etc. Is there any documentation on these? This is a builtin set of tags, or a specific datasource? And why do we have hour, but not minute? Because of the 1m index resolution this might not make sense?

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

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? 

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.

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. 

I want to get an email notification via the monitoring when a tag has no value (connection lost).Any idea how to do this?

The trends in dashboard do not get updated.

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

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

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

Hi,sometimes a tag has a “bad” value.Is there an option similar to the iferror function in Excel, so that i can specify a fixed value if the tag is bad?Cheers,Marvin

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
