  1. Batch Cycle Time Analysis is a core requirement for any batch process. In this example use case, we will explore how to identify various phases of the process, summarize the findings in tables and visualize data at scale using assets using Seeq.
  2. Seeq's grouping functionality is helpful when you want to align multiple conditions and signals, but a signal (or set of signals) only applies to a subset of the conditions. Grouping a signal with a condition will only display that signal during the grouped condition. For example, here I have two temperature signals and a condition for each signal. I have used Profile Search to identify the profile for each signal I would like to compare. When I use Chain View or Capsule Time, the default will cause both signals to show up during each capsule. In this Chain View, the information of Reactor Temperature 1 is not relevant during the Profile Reactor 3 condition and vice versa: In order to view only the relevant signal information, I can use the grouping functionality in Chain View and Capsule Time to compare the relevant signals during each condition: 1) Select grouping in the toolbar. 2) Navigate to the grouping icon next to the condition in the details pane and select the signal that corresponds to the condition. Select multiple signals, if necessary. I can also view this in Capsule Time. As an additional option, I can overlay both signals using the One Lane and One Axis selections in the tool bar:
  3. Here is a nice a simple example from a question emailed in this morning. This can be accomplished in a couple of minutes using a combination of Value Search to create a condition that captures our "Pump Running" state and Chain view to filter our trends to only those "Pump Running" time periods Step 1 - Create a condition that captures your event of interest. In our simple example that will be whenever the Stage tag is != to "OFF". This step can be much more complex and use the full range of tools in the "Identify" category to refine your search to exactly the periods relevant to your analysis. Step 2 - Switch to Chain View and zoom to range you want to look at. You can also now add any other signals that might be of interest to view in the context of your "Running" condition
  4. Overview Chain View enables a nice visual of all the time periods stacked side-by-side; however, sometimes it is useful to create a new signal from all these capsules that has been scrunched together. Note this is different from "time warping" which realigns the samples by some amount. Signal scrunching keeps the relative sample alignment the same within each capsule - but it does move each "snippet" of the signal next to each other. Step The best is to use Chain View and below method is applicable if there's a need to create a new signal. This requires a Manual Condition with a single capsule so that we know the starting point where we will calculate delays from. $delay = timesince($ManualCondition,1min,$Running) $signal.within($running).move(-$delay,30days) CONTENT VERIFIED MAY2024
