File Device - Migration to AS6.3

Ask Questions
1

Hi everyone,
I’m currently facing several challenges while migrating from Automation Studio 4.12 to 6.3.

The latest issue I’m dealing with concerns the handling of File Devices.
In my project, I use file devices that are defined in the CPU configuration (for example, USER pointing to F:\), as well as dynamically created file devices using the DevLink function block, based on the current system configuration.

After downloading to the PLC, I get multiple errors in the Logger, all seemingly related to the file devices.

One concrete example is the use of the VideoPlayer widget, which relies on a file device defined in the CPU.
Similarly, I encounter errors for the file devices created dynamically with DevLink.

What precautions or adjustments should I consider to ensure correct file device handling in AS 6.3?

Thanks in advance!

Hi,

Did you try to change F:\ by USER_PATH ? This point directly on the USER partition of the PLC (works also on ARSim).

I have seen on a project that using USER as FileDevice name result as usable filedevice (TextPad widget).

I have replace USER by HD (Hard Drive) and I got no problem now.

Hope that could solve you issue :slight_smile:

Florent

Hi Florent,
I tried replacing USER with both HD0 and USER_PATH, but unfortunately the issue is still there.

Any ideas on what else I could try? Thanks again for your help!

Yes there is a new configuration for FileDevice and mappView, by default you cannot access it from external:

Check the parameter “File device whitelist”, you can add your FileDevice name and it should work :slight_smile:

I know there is also things with new roles, but I don’t think it’s link with VideoPlayer, it’s more for MappFile!

Regards,
Florent
