Dear Alex,
The tags I am browsing are CBP, but I can only browse upto block level but
the blocks parameters are not showing in OPC configurator and not even in
Matrikon Explorer.
When I add new block or compound in database using ICC, its showing in the
OPC tag browser but parameters are not showing so I can not select any
parameter.
And when try to add the same tag which is reading good in OPC explorer by it
alias name (01LTF_CWS.GB534_STAIND) using the item path
(11AW70\01LTF_CWS:GB534.STAIND) its gives error;
"The item definition does not exist in the server's address space"
Thanks.
Regards,
Imran
