I have a Sensor Factory that delivers two values, 10000 (100%) or 0 (0%). This sensor factory analyzes the status of three other sensors through the status () function. The sensor was created on October 10, and from that date until today it shows correct values in the graphics. The problem is that for dates prior to the date of creation of the sensor factory, in the graphics of the sensor factory I continue to observe a value of 100%. Ideally, before the sensor creation date, no value is displayed in the graphs. I need to solve this problem.
This is the code that I have in Define Sensor Channel:
( status (3709) + status (4304) + status (4433) ) < 30000
In Channel Setting I selected the display mode in percentages, where the maximum value is 10000.
