Background Monitoring thresholds is a common use case in the chemical industry, essential for maintaining consistent production quality and ensuring operational safety. Thresholds act as predefined limits, signaling potential issues in the process when exceeded. Failure to effectively monitor these thresholds can lead to production inefficiencies, equipment damage, and reduced product quality. Such deviations can be caused by factors like temperature fluctuations, pressure variations, or torque instability, as well as unexpected changes in raw material quality. TrendMiner provides an effective solution by enabling reliable and continuous monitoring of these thresholds. ChallengeThe challenge in monitoring thresholds lies in precisely defining and continuously tracking them. TrendMiner offers a solution by enabling users to set up monitoring through value-based searches, which can trigger automatic alerts. Additionally, the creation of context items can be activated to allow for detai
If you ever downloaded TrendMiner from our file server you might have noticed there are a lot of files on there. The .tar.gz files are the actual TrendMiner installation/upgrade packages. The .zip file is the connector installation/upgrade package. But do you know what these .md5 and .sha1 files are? md5 and sha1 are 2 different cryptographic hash functions. A cryptographic hash function is a mathematical algorithm that takes an input of any size and produces a fixed-size, unique output (hash) that appears random. It is designed to be secure, meaning even a small change in the input drastically changes the output, and it is computationally infeasible to reverse or find two different inputs with the same hash.TrendMiner provides the hashes of the installation packages for you as a customer to verify that the file you downloaded is identical to the one which is hosted on our server and the file was not corrupted during download.How do you do that?Download and open the .md5 from our file
Sometimes, for better visualization and monitoring, it is helpful to represent the durations of certain important events in the plant within a variable. This is possible in TrendMiner by following a couple of steps.First, it is necessary to create a slope tag, from 0 to 1, that connects the start and end points of the event.This can be done with a conditional formula and time changes. For example, an event from the moment a batch starts until the “Phase 3” starts: It is important that the obtained variable consists of constant slopes from 0 to 1 and from 1 to 0. We do not want it to remain constant at values of 0 or 1 for long periods, as this could affect the second step of the workaround. This is why time shifts are used, indicating only the exact moment of start and end.Secondly, we need to transform the slope tag into another variable that indicates the duration of each slope. This is done with the formula 'if((a-b)>0,1/(a-b)/60,,0)' following the explanation provided below (to

Creating clear and effective graphs is a vital skill for anyone involved in data presentation. In process engineering, the ability to visually convey complex information can significantly enhance the impact of your work. However, not all graphs are created equal. Poorly designed graphs can mislead, confuse, and obscure the very data they aim to highlight. This functional tip outlines essential best practices for making enhanced TrendHub views that are both informative and visually engaging. By following these guidelines, you can ensure your graphs not only accurately represent your data but also resonate with your audience, facilitating better understanding and decision-making. Keep It Simple: Avoid clutter by minimizing gridlines unless they are necessary. Try to avoid displaying excessive context items unless they are needed to emphasize a reoccurring issue. Consider whether all data actually needs to be displayed in the focus chart, or if keeping longer-range data i
In industrial data analysis, precisely examining short events is crucial for optimizing processes and preventing disturbances. Short events, which are shorter than the index resolution, present a unique challenge as they can easily be overlooked. Here, I will show you how short events can still be analyzed in TrendMiner using a value-based search.Examples of short eventsExamples of short events include sudden pressure spikes in pipeline systems, which may indicate valve malfunctions or blockages, temporary temperature fluctuations in reactors, which can point to unexpected chemical reactions, and brief electrical spikes in systems, which may signal short circuits or overloads. Analyzing these events accurately allows for taking preventive measures and improving process stability and system safety. Background on indexing in TrendMinerTrendMiner uses indexing to enable fast, interactive visualization and analysis of time-series data. When a tag is accessed for the first time, it undergo
Background Fluctuating process parameters in the chemical industry present a significant challenge as they can impact the efficiency and quality of production. These variations can be caused by inaccurate measurements, unstable raw material quality, or insufficient process controls.For instance, Torque fluctuations in machinery may lead to mechanical damage, compromising operational safety. Temperature fluctuations in reactors can affect reaction kinetics, resulting in inconsistent product quality. Likewise, pressure fluctuations in pipelines or reaction vessels can affect product consistency and equipment safety. ChallengeManaging fluctuating process parameters may require setting and monitoring thresholds, tracking the range of variations, and creating context items. TrendMiner simplifies this by allowing users to define and oversee limits, measure fluctuations, and visualize all relevant data on a dashboard. SolutionDefining upper and lower limitsIn this step, upper and lower torq
BackgroundManufacturing plants often rely on both railcars and trucks to ship their products to distributors, retailers, or directly to customers. The choice between these transportation methods depends on various factors such as the nature of the goods, cost, distance, and delivery time requirements. Railcars are typically used for bulk shipments of heavy and large quantities of goods, such as raw materials, chemicals, and pellets, due to their capacity to transport large volumes efficiently over long distances. Conversely, trucks offer greater flexibility and are ideal for shorter distances and time-sensitive deliveries, providing door-to-door service and easier access to various destinations. This combination of transportation methods allows manufacturing plants to optimize their logistics and ensure timely and cost-effective distribution of their products. ChallengeKeeping an accurate count of how many vessels have been filled can be a challenging task for manufacturing plants, par
Gather Data Sources & Learn the Data Flow: Think beyond your data historian and understand the ecosystem. When initiating a pilot with TrendMiner, most discussions center around connecting to a data historian, where the process/manufacturing sensor data resides. However, to maximize the pilot's success, it may be beneficial to integrate other sources such as Laboratory Information Management Systems (LIMS) and Manufacturing Execution Systems (MES). Your Customer Success Manager can provide insights into which use-cases would benefit from such additional data integration. Even if you are not within the IT organization, having a basic understanding of how data flows through various components of TrendMiner is crucial for effectively communicating with stakeholders across different departments. TrendMiner’s Data Architect can clarify how the platform acquires and processes data. Get Buy-In from End Users: Consider who will be the end user for TrendMiner. Those working in Operations,
Often, we want to analyze or report on key KPIs, such as consumption, production, average temperatures, or maximum values of critical variables. However, these data need to be analyzed separately based on the recipe they correspond to.In TrendMiner, it is possible to unify all workflows so that reports for multiple recipes can be obtained with a single process. This is due to the ability to include the “constant” condition in the Value Based Search and to add string variable calculations. Here’s how it is done:Prepare the View: Load the tag indicating the recipe name and the rest of the necessary tags to create the report. Perform the Search: Go to the search menu and start a value-based search. The condition will be: Recipe name tag CONSTANT. The results obtained will correspond to the time period indicated in the context chart. Add Calculations to the Search Results: String Variables Calculation: Start value of the recipe name. This calculation will indicate which recipe each of t
BackgroundThe material management department needs the daily consumption of caustic to order the correct amount from suppliers and avoid shortages or excess.This is calculated from the reactor's weight sensor after each of the approximately 20 daily discharges.Before TrendMiner, we manually recorded these weights, a tedious process prone to errors, missing data, and a lack of consumption analysis. ChallengesUnderstand the normal daily raw material consumption to request the needed amount from providers and optimize inventory space. SolutionCreate a formula to create the derivative of the reactor weight only when it's negative (discharge). Value based search to search every day in the last 6 months Add calculations with the day name and the integral of the formula (daily consumption) Export report Results and value-A report of the last 6 months was created in 10 minutes, the same amount of time that it takes to manually get the report of 1 day. From now on, only 1 click is needed

TrendMiner does not support changing the (interpolation) type of a tag in the data source. This implies that for example when you change a tag from linear to stepped interpolation in your historian the tag will not load anymore in TrendHub and an error will be shown. You will also notice that the tag index can no longer be updated and goes to a STALE state.TrendMiner support can typically derive this from the logfiles, but if you already know this is the root cause of the problem then there are a few steps you can perform to resolve the issue.Refresh the tag cache manually in ConfigHub for the data source the tag is synced from (or wait up to 24h for the changes to be synced automatically) Restart the tm-compute service in ConfigHub or Edge Manager. Keep in mind that restarting tm-compute will entail downtime for the users (typically a few minutes). Re-index the tag. Edit and save all calculated tags and searches which depend on the changed tag (it is not required to make any chang
