Did the sampling frequency changed over the years?

I'm working on identifying the falling and rising edges of the VAL_23-KA-9101-M01:HSI.StatusMotorOn signal. For that and shifting the TS and rest the values, if I get -1 is a falling edge and for 1 it is a rising edge.  For the first row it works fine:  But I’m also getting a lot of values different than 1 or -1. Especially for more recent years. I guess that the problem is at the aggregating step, since I downloaded the data at a 1m frequency I get not int values for some records. Now, I was trying to download this TS at a 1s frequency, but I get a different number of records depending on the year.  E.G. for 2014 I get 34 records for a 10 days time windows with a granularity 1m.  If I do the same but for 2020 I get 1411, much more than for 2014, but still a tenth of the expected count.  If I change the granularity to 1s, I still get the same number of records, but with more precision in the time stamp:   Considering this, is there a recommended granularity to download the data and min

Cognite Data Fusion: ChartsPlanned for development

Celanese - CriticalThe ability to overlay other transactions on time  series data or create time series from transcations is necessary when troubleshooting. For example, i might be analysing several time series tag and i would like to plot work order and notification dates and/or other events on the same plot. This will really help us do better Root Cause Analaysis.

Quick Data lookup for Infield line itemsGathering Interest

For line items in Infield, Operations has requested to be able to see what the most recent previous readings for it were to determine if reading is going up or down at a critical rate.  Maybe a button on the line item that will quick trend the line items input data.  Or just a list of the last inputs.  Either way, we need a quick way to get history on these readings.

InField: Hide measurement reading tag from end userGathering Interest

On behalf of Celanese Units:  Acid South, Vinyl Acetate, UtilitiesAs a process expert doing rounds on a mobile device it is not necessary to see the measurement reading time series tag associated to checklist item. It is confusing and takes up space on the mobile device. We can see/find it on trends when we are looking for it, if needed.  Need a way to hide  by default this when setting up a template or set to hide?

Cognite Data Fusion for Domain Experts

This discussion is linked to the course Cognite Data Fusion for Domain Experts.A data-driven approach to maintenance is more efficient than relying on a fixed schedule or fixing something once it’s already broken. There are plenty of opportunities around us to take advantage of smart maintenance. Look around in your home, your office, or think of your work tasks. Where could data-driven maintenance make a difference?Share your thoughts! For example, explain what data you have available or would need in order to do smart maintenance, and how this would be an improvement of current methods.

Cognite InField: We need flexibility on checklist designGathering Interest

It would make sense that checklists can be created not just as a list but also as matrix or tabular formats. It will allow flexibility in how data is entered, captured and digitally recorded.

In CDF, we have a back button - need a forward buttonGathering Interest

There is the arrow on the left hand side of the screen for CDF to go backwards.  Please add a corresponding arrow to return to the screen from which you just went back.  Makes navigating back and forth between data very easy.

Different types of edges connecting nodes in FDMUnder construction

Hi, So far, I have the understanding that you can add edges between nodes, however, not different type of edges.In a watercourse, one would have several hydro power plants, reservoirs, etc.. and different water routes and flood routes connecting these objects (nodes). These connections would be of different type of edges, which seems to be a lacking feature in FDM if I am correct. Having this function available in FDM would be helpful in developing a data model for our water courses :)

InField - Filter on state in checklistGathering Interest

Entered on behalf of Celanese VAM Unit InField SuperuserAs a shift Captain I would like the option to filter for only Not Ok within the checklist before I approve it. I am only interested in reviewing those items and address them as needed.  This will save time and human error from scrolling to find the Not OK ones (and see the comments and images attached.   You should be be able to filter on any one of the states (e.g. To Do, N/A, OK, Not OK, etc)

Give error message in Python SDK when number of datapoints more than limit

We are fetching quite a lot of data from CDF, both raw and aggregated, and we have experienced error messages from Postman and Java requests when the aggregated number of datapoints are exceeding the limit (10.000), but we have yet to experience this for the Cognite Python SDK for raw data (limit 100.000). Is there an error message implemented for this intention? From the code in the SDK in GitHub it appears that if the data is exceeding the limit then it would return an empty list, which is a very dangerous return setting. Best regardsOliver

Explore a Live Stream of Industrial Data with Power BI!

Do you know what courses are available for you to explore the data from the Open Industrial Data project?Cognite Academy creates e-learning courses with an emphasis on providing hands-on experiences so you can learn to use Cognite Data Fusion through interacting with real industrial data. In most of our courses, the training data we use comes from the Open Industrial Data (OID) project, a live stream of industrial data from the Valhall oil platform. While the data is from the oil and gas industry, it is relevant for all asset-heavy industries as it provides insights into dynamic industrial processes. In this article, I will share a series of CDF & Power BI courses where you can explore the Open Industrial Data and solve a simple use case in Power BI: Introduction to CDF & Power BI  In this course, you will connect Power BI to CDF, and retrieve the Open Industrial Data to learn how filtering and aggregation work with the connector in Power BI.  CDF & Power BI: Solving

Cognite Replicator

A common setup that we have at Cognite is having 3 different environments: development, test and production. We have one specific Cognite Data Fusion (CDF) project for each of these environments. This setup allows to develop new features without interfering with production data. Also, it makes the deployment of new features to production much safer, since they are tested before.Sometimes, you still want to have the data you used during your tests, in your production environment. For example, if you extracted some data from sensors and saved them as time series in CDF, you may want to keep this historical data when you move to production. Same goes with files, assets, datasets, functions etc. Another example could be the replication of the data from a full production CDF project, to one of your customer’s project, containing only a subset of the source one.At Cognite, we have a python package (available at https://pypi.org/project/cognite-replicator/) whose purpose is to copy the select

Cognite InField: Ability to view Time Series Data Against Direct Links and RelationshipsPlanned for development

This is fundamental that when i am searching a tag in Infield e.g. HE1300 or V32401, i should be able to get all my time series data associated to that tag in the Infield view. Currently, only direct links are shown in the infield app, so if i really want to search a time series, i actually have to query the instrument tag itself. That is not value adding and defeats the contextualization and relationship achieved in CDF. This is really important to get fixed.

Can the signals of warnings, alarms, and failures be used to tag anomalies and/or failures in the compressor?

There are some signals that in the names or the description have the words: alarm, warning, or fault. E.G. There is this alarm signal, (in red ) that I’m comparing with one of the vibration signals.  And the alarm seems to be on when the vibrations are close to 0 and the Compressor is off. I’m plotting the label as a combination of the name and the description, but the externalId of the alarm is: pi:160268In most cases that alarm is on when the compressor is off, except in this case, Where I do not see any problem with the vibration signal: There are these other two alarms, from the plots: one is on when the compressor is off and the other one when it is starting up. But I do not see any strange behavior in the signal when they occur. Besides the alarms, I’ve also looked into some of the fault signals but those seem to be on for very long times: Is there another way to use the alarm and fault signals to label anomalies or failures? I don’t know if using the vibration signals is the bes

InField checklist - A way to capture A/B pumps stateGathering Interest

On behalf of process experts at Celanese Acid South unit: There are several A/B pumps. When one is running the other is not. Currently we have to create template with a single item for all pumps and mark the ones not running N/A one-by-one. With the number of A/B pumps running this is a bad user experience and takes a lot of time.  If Pump A is running, Pump B is not:It would be ideal to select Pump A in the checklist and enter in the reading. With Pump A running and we enter the measurement, then it would know to mark Pump B as N/ (since they are mutually exclusive)Please work with James Hudson on details of use case.

Cognite Seismic Service [Limited Availability]

Hello we have very good news for you, Seismic Service reached Limited Availability. What does it mean for you? A more mature and resilient Software as a Service offering supported by Cognite, and only one step away from being general available. In this particular case the main difference between Limited and General availability relies on the specific cloud support vs a cloud agnostic offer. Why was the Seismic service built? Because seismic data is a key asset for many companies in the Oil and Gas industry, and it represents a big portion of the data a company might own. The reason for this is that seismic data by nature is very large and complex to store and access quickly. In Cognite, we built the Seismic Service that allows you to store data in the cloud, search for a particular seismic line and stream it in seconds. All these functionalities are powered by CDF. Seismic Service enables you to:  Have centralized access for 2D and 3D post stack seismic data Full control on who acces

Option to set My Favorites Trends that would be auto checked in Trends for each asset in Trends View. I can learn the names/ids of the time series coming in that I care about and set them as favorites to check by default.  Even better would be to have ability to set Unit Favorites/Group Favorites AND have personal favorites where you could decide with you want set as default to open on Trends page. . then As a Learning Facilitator ability to set unit/team favorites to make it easier to onboard new employees and to make sure process experts are using all the features available to the
