Hello !
I create a TPSOPCConnector component at runtime.
Then I fill the OPCConnector with OPC Items like OPCConnector.addItem((c as TPSFloat).Caption, (c as TPSFloat), vpValue);
How can I remove an Item at runtime ?

Hi Rainer,
use OPCConnector.Links.Delete() to remove them.

Hi Otso,
Thank you.
My OPCConnector.links.count shows me 5332.
Now I want to delete the links:
for i:=0 to count-1 do
OPCConnector.links.delete(i);
When i is 2766[5332/2] it throws an error “Listenindex error”.
Why ?

Hi Rainer,
While it’s a list, the indexes are re-arranged after each insert and delete, so you’re loop goes over index after half of items are deleted.
You can clear the list e.g like this:
for i:=0 to count-1 do
OPCConnector.links.delete(0);
or like this
for i:=1 to count do
OPCConnector.links.delete(count-i);
