Online change required for source code uploaded from controller
What happens?
When going online, an online change is required, although no changes have been made to the project.
When does the behaviour occur?
The source code has been transferred to the controller with the option 'Use compact download' (dialog 'Project Settings', category 'Source Download'). Afterwards the source code was loaded from the controller into PLC Designer again and an attempt was made to go online. Although no changes were made, an online change is required.
Which products are affected?
PLC Designer from V3.0
Short-term measures:
Deactivate the 'Use compact download' option in the 'Source Download' category of the 'Project Settings' dialog (menu 'Project' > 'Project Settings') before loading the source code of the PLC project to the controller.
Evaluation/Recommendations:
If the source code of a project has been loaded to the controller with the 'Use compact download' option activated, an online change is required when going online from the controller with this project. The option 'Use compact download' is deactivated by default. The source code download to the controller is not performed automatically by default but must be performed manually (menu 'File' > 'Source Download').
