From the KPI list page, click on the menu option ‘Configuration’ for Energy Efficiency. You will then be taken to the configuration page. Here you need to select an appropriate sensors to provide input data for the formula:
EE = Energy consumption / Actual production rate
Once this is done, you have enough to click save, upon which your KPI will become active. For information on how to set up targets, read the article How to use targets.
The specifications for the required sensors are as follows:
Energy consumption: This sensor needs to be supplying data on the energy consumption of your machine in kWh.
Actual production rate: This sensor needs to provide the actual production rate, so for instance the number of products produced per minute.
