Commissioning a Project
7.5 Transfer
• Online testing of the project on the HMI device
Online testing means that the HMI device and PLC communicate with each other during
testing.
Perform the tests, starting with the "Offline test", followed by the "Online test".
Note
You should always test the project on the HMI device on which the project will be used.
Check the following:
1. Check the correct layout of the screens.
2. Check the screen structure.
3. Check the input objects.
4. Enter the tag values.
The test increases the certainty that the project will run error-free on the HMI device.
Requirements for Offline Testing
• The project has been transferred to the HMI device.
• The HMI device is in "Offline" mode.
Procedure
In "Offline" mode, you can test individual project functions on the HMI device without them
being affected by the PLC. PLC tags, therefore, are not updated.
Test the operator controls and visualization of the project as far as possible without
connecting to the PLC.
Requirements of Online Testing
• The project has been transferred to the HMI device.
• The HMI device is in "Online" mode.
Procedure
In "Online" mode, you can test individual project functions on the HMI device without them
being affected by the PLC. PLC tags are updated in this case.
You have the option to test all communication-dependent functions, e.g. messages, etc.
Test the operator controls and views of the project.
