SD Card: Folder Report Function

Notes ♦

The function reports only on the types of files that are linked to a particular folder. For example, each Data Table folder (DT) may contain a maximum of 64 .udt files. If Folder Report is set to DT folders, it only reports the number of .udt file. If there are other file types present in the folder, they are ignored.

♦

If there are fewer files than the maximum allowed, but the SD card capacity is exceeded, SI 66 will indicate SD Card Full.

♦

Use SB 343,SD: File Report in Progress, as a condition to running the function
