SD card use in Sim

[Controls Guy]

Would be handy to be able to have the Sim able to access media on the PC, whether it be an SD card, other drive, or possibly even a FAT32 partition on the hard drive.

No idea if that's possible, since the BRX has it own FS, to make it capable of dealing with Windows FS, assuming not.

It does. The SDCard simulation is just a directory called SdCard that lives in the same directory as the sim executable.

I started the Sim from within DMD, browsed the file system, selected SD as the FS, had all 0's in the file sizes and so on, which is probably the default state.   I tried to mount it, and it said it couldn't do that in the Sim (makes sense if it's just a subdirectory on an existing FS).     So when does "Mount" apply?   When installing a new card in a BRX?   When accessing an SD card in a real BRX via DMD?

I have no idea what you are seeing. Mine looks just like the PLC. Starts empty, no files. That may be a bug in that simulator mode. Try running the sim as standalone then connecting.

I think probably more like a bug in my operation of the file browser.    I think it's probably working OK, just doesn't need mounted.  I haven't actually tried creating any folders or files or writing to it.   If I have any issues with any of that, I'll post again.

The SD card in the PLC is completely under control of the PLC.  The "SD Card" on a PC has literally THOUSANDS of programs CHANGING THE SIZE AND FREE SPACE of the "SD Card", only one of which is the Simulator.  Hence, it does NOT maintain the free/used values (why you see 0's).

Oh, yeah. It can't be mounted because it can't ever be unmounted. When you said zero files, I envisioned a directory full of zero length files.

Yeah, I created a FILELOG, and it works exactly as expected.   Thanks!
