The QR Data App enables you to query variable values of a machine directly with a smartphone. The zenon app is ready for use in just a few steps:
1. Configure QR code for required variables in the zenon project, either for a machine or other equipment, with just a few clicks of the mouse.
2. Save or copy the QR code, print it and place it directly on the machine.
Scan the QR code with a smartphone, and the variable value from zenon is shown directly. Values such as energy consumption, temperature, fill levels etc. can be read, for example.
