#23 problem registering items
I can browse the opc-server (T3000) using JOpcBrowser for all items (although it is very, very slow), but when I try to register an item to a group the UnableAddItemException is thrown. I am looking for tips on why the browsing is so very slow, and for what reasons items can not be registered to a group. Any help would be very much appreciated.
Did you register the group before ? I had speed problems too, if many (over 1000) items had to be registered. The solutions was, that I registered one item, read the value and deregistered the item (dont't forget to actualize the group). Therefore I was able to read the values of many items.
