While Seeq is working towards enhancing our features in the Histogram tool, here are a simple workaround commonly used to create a histogram for multiple signals with display times in chronological order. Step 1: Start by loading all of the signals we want to include in the matrix into the display. Step 2: Create a monthly condition with a property that split the years and months (YYYY-MM) from the initial date format (YYYY-MM-DDT00:00:00Z) using the formula tool. Formula 1 - month_withProperty $monthly = months("Asia/Kuala_Lumpur") //split the years and month
Has anybody attempted to calculate equivalent or factored gas turbine starts and/or hours? Something similar to GE's GER3620RevP document on pages 35-36. Looking for tips or best practices as our company uses multiple fuel types and operating profiles. Our corporate-level operating data historian is not always the best, necessitating the use of multiple signals to determine a turbine start or stop.
There are various methods to do this. The easiest method is by using the max() or min() functions in the Formula Tool, which are available beginning in Seeq release R21.0.40.05. Here is an example for creating a new signal which is the maximum of 4 other signals: $a.max($b).max($c).max($d) You can also see additional information in this related forum post.
Guest posted a topic in General Seeq DiscussionsThis question comes up fairly often, so I thought best to put one solution in the forum. Please feel free to suggest other approaches. Say you have two temperature signals and you want a third signal that shows always uses the larger value of the two. The logical thought is an if statement, e.g., in pseudo-code: If temperatureA > tempertureB then temperatureA else temperatureB So the question often hits Seeq support, as "How do you do an IF statement in Seeq". Seeq, at this time, does not have IF statements, but we have some techniques to achieve the same thing. For this p
