I have an .scf file with 72 tags and several tag groups in it. If I open the tag engine without the usb adapter, I can read the tag group names with the get group list.vi. The tag group names are listed in black letters when wired to an indicator. When I plug in the usb ethernet adapter, immediately the group tag names are greyed out in the indicator without even running the vi. If I put a tag constant on the block diagram and try to select a tag name with the pointer, no tagnames pop up. It worked yesterday and my IT. department sent down a shockwave and flash5 update download when I booted up this morning. anyone have any ideas??
