  2. Hi Thorsten, The connector configuration files are always being monitored for changes. Just adding a white space and saving the file will be seen as a change and initiate Seeq to reconnect. You can reconnect without indexing if you want, or you could have it index depending on how the connector is configured. If the configuration file has "OnStartupAndConfigChange" set to true for this connection, any white space change will be noticed as a change and indexing will be triggered on save. Alternatively, you could have this parameter be false and set the date/time in "Next" to be some time in the past. Then when saved, the connector will realize it needs to index as the next scheduled date is in the past and will find and index the connection. If this parameter is false and the date/time is in the future, the connection will be attempted again on save with a white space change, but indexing will not occur until the next scheduled date. Regards, Joanna
  3. Hi Joanna, thank you. Can you give me a hint on where to make this setting inside the configuration file? Regards, Thorsten

  5. Hi Thorsten, Current releases assume the connection is closed after the SQL server connection is lost and do not automatically try to connect again. Instead of restarting the Seeq service, you could edit the SQL Connector configuration file to resume a connection after the SQL server is rebooted or SQL service restarted. This has been addressed in an upcoming release (0.47.00). After you upgrade to this release when available, Seeq will make repeated attempts to connect to SQL servers that are appearing as disconnected so that the connection will resume when they become available again. Thanks, Joanna
  6. In this example we want to plot both temperature signal and a model signal vs relative humidity in one scatter plot using Seeq. Here are the Steps: RAW Data: Temperature (Area A) Temperature (Area B) X axis - Rel humidity (Area A) Step 1. Delay one of the signals to make sure the data points for both signals are not aligned Model (Area B) $TempAreaB.delay(1min) Step2. Combine the model and the temperature into one signal and set the max interpolation to 1 sec so it doesn't draw a line in between samples Model & Temp Combined (Area A) $Temp.combinewith($Model).setmaxinterpolation(1sec) Step3. Create a condition per each sample in the Temperature and Model Signal Temp Condition (Area A) $Temp.setmaxinterpolation(1sec).isvalid() Model Condition (Area B) $Model.setmaxinterpolation(1sec).isvalid() Step 4. Go to Scatter plot and select "Relative Humidity" as the X-Axis and "Model &Temp Combined" as the Y Axis Step 5. In Scatter Plot, select Model condition and Temperature condition for condition based coloring the sample points
  7. Hi, I configured Seeq to use data from a SQL Server database. However, after rebooting the machine hosting SQL Server or restarting SQL Server service the connection in Seeq is not reestablished. Error message: Error getting data: The target datasource is disconnected or no longer exists I have to restart Seeq service to get this resolved. Is this a known issue and is there a way to get around this? Regards, Thorsten
  8. Hi Cezary, We are testing Seeq's compatibility with Windows Failover Clusters now, but we do not currently have any customers running in this configuration. We recommend leveraging high availability features in your infrastructure to provide failover capabilities, as we do for our SaaS offering. I'll report back on the results of our Windows Failover Clustering testing as soon as we have them.
  9. Hi Ali, in addition to @Sanman Mehta's answer if you need just the difference between the values: You can use runningDelta() for getting the change of the value from sample to sample or use Signal From Condition and apply "Delta" as summary statistic. That will give you the difference between values at end and start of the capsule. Regards, Thorsten
  10. Hi Ali, check out this link: https://www.seeq.com/resources/seeq-university/297-using-formulas-for-calculating-rate-of-change-on-a-process-variable Regards, Sanman
  11. Hello, Is there a way to find the rate of increase/decrease of a target signal per time period, then trend the delta points? Thanks

  13. 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 "join" together the Phase 1 and the Final Phase using our Composite Condition Tool. You should now see that the Combined Condition starts at the beginning of Phase 1 and ends at the end of the Final Phase. Now that we have identified this period of interest we could do a variety of calculations using the Signal from Condition tool. These calculations could include average duration of the Combined condition, maximum temperature during the combined condition, etc. You may notice in the Capsules pane that the "children" didn't inherit the Batch ID of the Parent. If you want advice on how to complete this you can reference this article. --Morgan
  14. Hi Adam Thanks for reaching out. I have logged this feature request under SUP-20249 in your company support portal. You will be notified when this is implemented into the product. If you have any other questions or concerns please let me know.
  15. When opening a Dashboard in View-Only mode: please default to "comments pane minimized" rather than "comments pane open". This is particularly important on mobile where screen real estate is limited. Otherwise, as you can see in my phone screenshot, the comments pane takes up the whole screen and the actual content is hidden to the right.
  16. Hi, Does Seeq support a redundant architecture deployment (Windows Clusters OR NLBs)? The KB article about architecture does not seem to specify anything about this. I am not asking about the seeq connectors but about the actual web front end application. If Clustering is supported are there any guidelines how to deploy or should the standard installation steps still be valid?
  17. Hi Thorsten, Thanks for the update, that's solved my problem. Thank you both again. Best regards Chris
  18. Hi Chris, you can use Deviation Search for this. I altered @Lindsey.Wilcox example by using another signal that acts as the limit: Using Deviation Search you can find capsules, when the value is above the threshold: In the last step you combine the conditions to get the desired capsules. Make sure you uncheck "Inclusive of B", otherwise the resulting capsules are extended by the duration of B. Hope this helps. Regards, Thorsten
  19. Hi Lindsey, Thanks for the swift reply, I think this might go some way to solving the problem. The Value I'm wanting to search for varies as it's a signal. How would you go about doing that. Thanks in advance. Best regards Chris
  20. Hi Chris- I think this can be achieved using a combination of the Value Search and Composite Condition tools. In the following screenshot, I have a signal (temperature) and a condition (Start Capsule). Let's say I'd like to create a new condition that starts at the start of each capsule in Start Capsule and ends when the temperature is 90. First, use the Value Search tool to identify when the temperature is 90 F. This results in several small capsules each time the temperature is 90 F. Next, combine these 2 conditions using the join operator in the Composite Condition tool: This results in a new condition (Start to Temp=90) where each capsule starts at the start the Start Capsule capsule and ends at the start of the Temp=90 capsule. Please let me know if you have any additional questions. Thanks, Lindsey
  21. I'm trying to create a startup capsule for a gas turbine. How do I create a Capsule using the start of one Capsule and end when a signal reaches a certain value? Thanks in Advance Chris
  22. Hi Banderson, as a workaround you may use periods(): periods(8.5h, 1d) creates a shift of 8.5h each day starting at midnight. Following shifts may be created by adjusting the parameters of periods() or moving these shifts (e.g. $shift1.move(8.5h)). Regards, Thorsten
  23. Make the shift formula except a floating point number instead of just an integer. Shifts are commonly 8.5 hours long once lunch is added.
  24. Hi Banderson, you can create a duration signal from each capsule in a condition, using "signal from condition" tool. As you may know these point and click tools create a Seeq formula underneath. So after using point and click signal from condition tool, you can find the syntax of formula in item properties of that calculation. You can copy this syntax and paste it in Formula and use it to further develop your calculations.
  25. Hi, I am trying to find the duration of each capsule in a condition. I would like to do this using the formula tool as it will eventually be part of a longer equation. I can only seem to find a duration equation for individual capsules and not for each capsule in a condition. My signals are: $mir = mill is running (condition) $8 = 8.625" wall thickness (condition) Thanks,
  26. Hi Yoni, The error occurs due to some missing dependencies that the Seeq module requires when launching the designer. Seeq will add the ability to link to Seeq content from the designer and that requires certain modules. Can you check to see if the Vision module is installed on the Ignition server? Usually adding that module will resolve this issue. Very Respectfully, Mike Cantrell
