DataSet access to mounted drive

[tommy3000]

Hello together

Short question, I try to run my station locally on my development enviroment. On my system I only have a C drive. I tried to solve that issue, mounting a folder to d drive, unfortunately DataSetManager having a problem with error message 'Can not create folder for .bin-files'

I've seen, in the Digital Machine, the recommandation is, to change all paths of the DataSetManager to C:, but I want to avoid this, because it's important for me to switch quickly between simulation and real machine.

I tried to run the station with an usb sick monted as d drive, what is working fine.

Technically, I don't understand the problem. Is TwinCat not able to create folders on mounted drives?

Extra question, on my investigation I found an icon, when I was debugging. What is the meaning of the 'S' in the icon?

Thanks in advance

What I know for sure is that TwinCAT cannot access network paths, even if they are mapped to a drive letter. Looks like the same applies for drives created using the subst command. As far as I know, these drives only exist in the user session. And the TwinCAT XAR does not run under your user account.

About the s: This is a static variable (VAR_STAT), i.e. it is a common variable for all instances of the type.

Is it possbile to change the DataSetAddon? Depending on the simulation mode, a different path can be selected. Similar to switching between real peripherals and simulation peripherals.

This is certainly a good idea, but currently, only Port parameters (i.e. connections to peripheral channels) are aware of the simulation mode. I.e., this cannot be changed in the addon object definition.
