FAQ: I've created a condition for a particular event of interest and now I would like to create a signal that is the running count of these events in a given time period. This analysis is common in equipment fatigue use cases when equipment degrades slowly based on a number of cycles (thermal, pressure, tension, etc) that it has undergone during it's life or since a last component replacement. Solution: We can convert each of these capsules into a signal comprised of a single sample (with value of 1) per capsule, then take a running sum of this new signal over the current equipment life condition. 1) Use Formula to create a signal with a constant value of 1 and a sample every 1 second. (1).toSignal(1sec) 2) Use Signal from Condition to create a new signal with a single sample of value 1 per capsule. Take the average of the "1 signal" during each of the event capsules. 3) Use Formula to calculate the running sum of the 1 sample per capsule signal during the Current Equipment Life capsule. $OneSamplePerCapsule.runningSum($CurrentLife).toLinear(7d)
Hello Seeq, I have a bad actor pump that requires relatively frequent maintenance and replacement. I am using a flow measurement in Seeq to indicate whether my pump is operating or not but I'm having trouble creating a new signal that captures the running hours/days of my pump at any given time. I was able to use Signal from Condition to give me each operating periods total duration (see attached) but I'm looking for a more continuous signal. Please let me know if there is a way to accomplish this in Seeq.
