Background In this Use Case, a condition was created to identify when a compressor is running. Let's say I'd like to extend each capsule in this condition so that instead of ending when the compressor turns off, it ends when the next compressor running capsule starts. Method The method used depends on the Seeq version. Seeq R21.0.42 and Later Version R21.0.42 introduced the .growEnd() operator; this operator grows capsules in in a condition by extending the end until the start of the next capsule. Earlier Versions (Before R21.0.42) 1. First, create a condition that is the inverse of the Compressor Running condition. This can be achieved using the .inverse() function in Formula 2. Next, extend each Compressor Running capsule so that they overlap with the Downtime capsules. This is achieved using the .move() function in Formula. 3. Finally, combine the Downtime and Compressor Running - Extended conditions use the union logic in the Composite Condition tool.

Hi All, I'm trying to get a solution for the missing value imputation. Is there any ways to it like filling missing values with "Mean" or "Median". Below is the screenshot for the same. Regards, Jitesh Vachheta

For reporting purposes, I want to calculate statistics based on the most recent period(capsule) and display that along with the periods immediately preceding it. This can be done in Organizer using the custom date range by creating a Periodic Condition and selecting the capsule closest to or offset by one from the end. The same date ranges or capsules relative to now can be created in Seeq Workbench as well. Organizer: Workbench: We create the same condition as the above Organizer in Workbench by following the methods below. The first method defines how to create conditions for current and previous conditions for years, days, weeks, shifts. The second method includes an extra step that is necessary for current and previous months and quarters since the exact duration of these periods can vary based on the number of days each month. Method 1 - when the length of time in each period is definitive (e.g. year, week, day, shift). This example shows how to create conditions for "Current Week" and "Previous Week" 1. Create a Periodic Condition for "Weekly" using the Periodic Condition tool. 2. Create a Condition around the current time ("Now") using Formula --> condition(1min, capsule(now() - 1min, now())) 3. Use the Composite Condition tool to create a condition for "Current Week" when the Periodic Condition "Weekly" touches the tiny capsule at "Now". 4. Use Formula to create a condition for the "Previous Week" --> $currentWeek.beforeStart(7d) Method 2 - when the length of time in each period is variable (e.g. month, quarter). This example creates a condition for "Current Month" and "Previous Month" 1. Create a Periodic Condition for "Monthly" using the Periodic Condition tool. 2. Create a Condition around the current time ("Now") using Formula --> condition(1min, capsule(now() - 1min, now())) 3. Use the Composite Condition tool to create a condition for "Current Month" when the Periodic Condition "Monthly" touches the tiny capsule at "Now". 4. Use Formula to create a Condition for the last day of the last period (in this case "Last Day of the Last Month") $currentMonth.beforeStart(1d) 5. Use the Composite Condition tool to create a condition for the "Previous Month" when the Periodic Condition "Monthly" touches the "Last Day of Last Month". Content Verified DEC2023

In some cases you may want to do a calculation (such as an average) for a specific capsule within a condition. In Seeq Formula, the toGroup() function can be used to get a group of capsules from a condition (over a user-specified time period). The pick() function can then be used to select a specific capsule from the group. The Formula example below illustrates calculating an average temperature for a specific capsule in a high temperature condition. // Calculate the average temperature during a user selected capsule of a high temperature // condition. (The high temperature condition ($HighT) was created using the Value Search tool.) // // To prevent an unbounded search for the capsules, must define the search start/end to use in toGroup(). // Here, $capsule simply defines a search time period and does not refer to any specific capsules in the $HighT condition. $capsule = capsule('2019-06-19T09:00Z','2019-07-07T12:00Z') // Pick the 3rd capsule of the $HighT condition during the $capsule time period. // We must specify capsule boundary behavior (Intersect, EnclosedBy, etc.) to // define which $HighTcapsules are used and what their boundaries are (see // CapsuleBoundary documentation within the Formula tool for more information). $SelectedCapsule = $HighT.toGroup($capsule,CapsuleBoundary.EnclosedBy).pick(3) // Calculate the temperature average during the selected capsule. $Temperature.average($SelectedCapsule) The above example shows how to select and perform analysis on one specific capsule in a given time range. If instead you wanted to select a certain capsule of one condition within the capsule of a second condition, you can use the .transform() function. In this example, the user want to pick the first capsule from condition 2 within condition 1. Use formula tool: $condition1 .removeLongerThan(1d) .transform($c -> $condition2.removeLongerThan(1d).toGroup($c).pick(1)) The output: Content Verified DEC2023

FAQ: I would like to create a condition for the summer season that runs from May 1 - September 30, but when I use the Periodic Condition tool to create a monthly condition and select the months May-September, I get individual monthly capsules rather than one capsule for the entire summer. Is there a better way to do this using Seeq's tools? Solution 1 - Using Seeq Point & Click Tools: 1. Use the Periodic Condition tool to create a condition for May. 2. Use the Periodic Condition tool to create a condition for September. 3. Use the Composite Condition tool (join operator, inclusive of A, inclusive of B) to create a new condition that spans from the beginning of May to the end of September. Solution 2 - Using Seeq Formula: 1. Create a monthly Periodic Condition selecting all of you "summer months". Note that while it looks like one long capsule at the top of the display pane, it is actually 5 adjacent monthly capsules. You can confirm this by looking at the capsules pane in the bottom right hand corner of the application. 2. Use Seeq Formula and the merge() function to merge adjacent capsules. The appropriate syntax for merging adjacent capsules can be found by searching the word "merge" in the search documentation bar within Seeq Formula and scrolling to the example to "merge overlapping AND adjacent capsules". Note now in the capsules pane there are still the individual capsules for summer months, but there is a new green capsule that spans the entire summer as defined in this problem statement.

I have a batch operation characterized by two conditions: The first condition represents the start of the batch and the second condition contains the end of the batch. Each capsule has the batch ID as a capsule property. How can I make a single condition that represents the duration of the batch by joining the start and end conditions?- 1 reply

Hi all, I have created a workbench with three temperature signals (x, y, z) and I have added six value search conditions (x Hi, x Lo, y Hi, y Lo, z Hi, z Lo). A High and Low condition for each signal. This has created a list of 95 capsules for the six conditions. I am exporting the summary data to excel. The information tab contains a list of my 95 capsules. However, the Capsule Summary tab contains a list of 285 line items. I am seeing the information for all three signals against each capsule ID, rather than just the signal that capsules condition was configured against. I have tried only selecting one signal and its two conditions and exporting. But I still get all 95 capsules and 285 line items. Not sure if I am doing something incorrectly? I expected the Capsule Summary tab to list just the 95 capsules with the relevant stats? I would like to avoid having to create a workbench for each signal and its conditions. Is there another work around? Also the time stamps in the excel export appear as EST despite my profile and workbench being set to GMT? TIA

A common analytics need is to create a signal with numerical values that are based on an existing condition. Users often want to translate a condition (on/off, good data/bad data, running/down, etc.) to a numerical value to be used in calculations. For example, a user may want to multiply a process signal by a 0/1 value based on when the process is down/running. This technique can also be used to replicate "if" logic or "if / else" logic, where different values are returned depending on if the condition is true/false. Converting a condition to a signal value can be easily accomplished in Seeq using the Formula Tool and the splice function. Here is an example where we convert a condition to a signal of 0s and 1s: 1. Use the Value Search Tool to create a HOT condition for time periods when the Temperature signal is > 90 degrees F: 2. Use the Formula Tool to convert the HOT condition to a 1 (when condition is true) and a 0 (when condition is false): 3. View the results in the trend. The new signal in lane 2 has a value of 1 when the HOT condition is true. Otherwise, the signal is 0.

FAQ: I want to create a condition where a trend is within a specific range of slope so as to identify instances where it falls inside and outside these ranges. Is this possible? -
Hi- I have a process that goes through several different stages during its operation, e.g. 'Stage 1', 'Stage 2', 'Off' etc. I'd like to determine a count or frequency that my process is in each of these stages. What is the best way to do this?
