Testing A Project - Siemens LOGO! Series Manual

Testing a project

Introduction
You have the following options to test a project:
● Test the project on the configuring PC
● Offline testing of the project on the HMI device
● Online testing of the project on the HMI device
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 navigation.
3. Check the input objects.
4. Enter the tag values.
The test ensures that the project will run as you intended 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.

You can test a project at a configuring PC, using a simulator. For detailed information,
refer to the "WinCC flexible" user manual and to the WinCC flexible and WinCC Online
Help.
Offline testing means that communication between the HMI device and PLC is down
while the test is being carried out.
Online testing means that the HMI device and PLC communicate with each other during
testing.
