1. ## Formula to create condition based on multiple criteria and analysis

Hey there, My question splits into two parts: Firstly, I want to create a condition based on multiple criteria: if signal A equal to 3, B equal to 4, C is greater than 5 than condition is valid. I know i could create 3 individual capsule and overlap them. Is there a simple way to use formula to do so? Secondly, in my analysis i have 10 signals and associated conditions(alert), then I want to know in the past 7 days how many alert in total(repeated instance or capsule doesnt count) ? and How long is the total alert time? Thank you
2. ## Identify subtle trends or step changes in a signal

Background: When looking to identify trends or step changes in a signal, we typically recommend an approach of smoothing the signal, taking the first derivative, then identifying when that derivative is positive or negative. This method works well most of the time, but employing this technique in combination with others can be more effective at capturing trends/step changes when the value change in the signal is more subtle. Solution: When looking for step changes, we can use a technique of calculating a range of the signal on a rolling periodic basis and search for when the r
3. ## Create function to calculate total duration with multiple conditions

Hello Everyone, I hope you are doing well. I need some help with creating a function. I have multiple conditions that I have created that tell me if the equipment is stopped, lag, standby, or other attributes. I want to be able to be able to: ADD Durations for when equipment is stopped and in lag OR when the equipment is stopped or standby. ADD Durations for when equipment is stopped but not in lag or standby. The example variables are in hours. Stopped (\$i5) Standby(\$i6) Lag (\$i) I would appreciate the help.
4. ## Creating Periodic Conditions Relative to Now

FAQ: For reporting purposes, I want to calculate statistics based on the current period to date and display that next to the periods immediately preceding it. This is easy to do using the custom date range tool in Organizer Topic (Creating a Periodic Condition and the grabbing the capsule closest to or offset by 1 from the end). Is there a way to create these same date ranges relevant to the current time in Seeq Workbench? Solution: We can create identical conditions in Seeq Workbench by following the methods below. The first method defines how to create conditions
5. ## Combining Different Phases of a Batch Process Into a New Condition

There are times when you may need to combine two capsule series to form a single capsule series. We've seen this is batch processing where a parent batch has two or more child series, perhaps representing operations or phases. For reporting or other purposes a capsule series where each capsule starts at the beginning for a capsule and ends at the end of another capsule. In this example we have a Parent Condition, Phase 1 Condition and Final Phase Condition. Say we want to be able to actual the average time starting when Phase 1 begins and Final Phase ends. In this case we can "jo
6. ## How to create shift conditions for different types of shift schedules.

FAQ: How do I create a condition for operational shifts if they alternate days and hours? e.g. (The EOWeO schedule) The following solution will keep the start times the same regardless of daylight savings. So, there will be an 11-hour shift in March and a 13-hour shift in November. For areas that don’t follow daylight savings a simpler solution can be found further below. Overview: To achieve the results described above the shift() function will need to be used in order to create the desired effects around daylight savings. If there was no daylight savings the periods() function wo
7. ## Join Capsules in the same Condition

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, cr
8. ## scaler Value Removal

Hi All, I've got few Scaler values in my data-set (E.g High,On,OFF) , I have convert all of them into Capsule by toCapsule() Function. Now wanted to remove only those capsules which are having "OFF" Status. Regards, Jitesh Vachheta
9. ## Creating Conditions for Seasons

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
10. ## Identifying Patterns in Discrete Sequences of Events

Use case: A piece of equipment has a start-up sequence in which it goes through different discrete states sequentially before completing the sequence and reaching steady state. When the equipment is off, the state is 0. When the equipment enters the start-up sequence it cycles through states 1-6 in the pattern "1-2-3-4-5-6". A successful start-up sequence will have all 6 states in the pattern "1-2-3-4-5-6." If a disruption occurs at any point in the start-up sequence the state number will read as state 7, thus a failed start-up sequence could have the pattern "1-7", "1-2-7", 1-2-3-7", etc
11. ## Oil and Gas Use Case

Upstream O&G Customer Use Case: I have created a condition for when my well is shut-in based on a value search on the down hole pressure. I've created another condition for the first hour after the well is shut-in. I would like to create another condition that runs from the end of my 1-hour after shut-in condition until the down hold pressure returns to within 10% of it's pre-shut-in value. Once I have isolated this period of time I would like to calculate an hourly rolling average over only that time period and do the same for my 1 hour after shut-in condition. Solution:
