I need to be able to backup and restore tag values to disk. These would be OPC type tags that are pointing to my PLC.
I can’t find any built-in way to do this. Does anyone have a preexisting solution for doing this?
I have several PLCs that have a common set of set points. I would like to be able to save them to disk and then write them back in or use this feature to copy set points to other PLCs. These PLCs do not live on the same network so that is why I need to backup to disk.
this would also behelpful when I want to do downloads to Allen Bradley PLCs and keep my Setpoints in a give PLC the same.
