PID Tuner could not find any steps in the data #7

Closed calania closed 4 years ago

Hello, today I found your website and wanted to try to tune a temperature PID controller. I have attached an excel file with my temperature, if the power was on/off and the time. The problem is that when I paste the values on the website I get an error reading

"PID Tuner could not find any steps in the data. Please make sure the data contains at least one step response. "

This even though the power is turned on/off multiple times causing the temperature and input to change. Have I misunderstood something isn't the step every time the input changes or is there a problem with the tool?

Sorry, when I started using the input values created from my pid controller and not manualy turning it off/on it started working. Thanks for the tool!
