Ok, I can see that I might be going down a dead end here, maybe someone can help. I can see where if I use the function load DTI from file, I can load am indexed DT table.
Assuming the operator does not know what the list of files that the management has given him, how can I get a list of udtf files that are on the SD card for him to choose from ?
I see the File Selector Browser, but it returns all files in the DT directory for selection. If I use the Store DTI to File, I must use a 1 for Parameter F creating all files. Then the operator will get csv, et al. listed in his file selector window.
I can see no handling for Files in the C# function so I suspect that I am nearing a dead end here.
The idea would be for management to ftp a file(s) to the plc that the plc operator could use and make changes to recipes in his plc.
