This problem occurs if the PCMCIA card was formatted under Windows XP. Windows XP used a type of formatting (Big DOS FAT) that is not supported by the GF-1 Panel. Contact Support if you wish to reformat cards correctly that were formatted in Windows XP.
Correct procedure when using Galileo up to version 4.20.x in Windows XP for GF1 Panels:
Do not format the PCMCIA card and carry out the project download using a serial download.

Cause:
A project was opened with an unknown target system. The target system configured in the project is not installed on the programming PC.
Solution:
Install the appropriate target system on the programming PC before opening the project
or:
Open the project and ignore the error messages => The PLC configuration is removed from the project. The required target system must then be selected in the Target Settings menu and the standard configuration must be added in the PLC configuration.

Cause:
Faulty PLC configuration: CAN libraries are added to the project in the Library Manager, however, the PLC configuration does not have the CanMaster.
Solution:
Add the CanMaster to the PLC configuration using "Insert element".

Cause:
In the Target Settings menu, the 'Support network variables' or 'CAN network interface' option was removed in the Network functionality tab. The library 3S_CANOPENNETVAR.lib is not automatically removed from the project in the Library Manager.
Solution:
In the Library Manager, remove the library 3S_CANOPENNETVAR.lib manually from the project.

From Galileo Version 5.2.x the error message can be stopped by touching the screen with your finger. The bar is visible as long as it is "held" with your finger.

Alternatively, it is also possible to set how long the error bar is to appear. In the Runtime folder of the compiled project, the file grs_log."language" must be opened with an editor. The display time can be set here in seconds (standard 2, maximum 9)
