Hi Ilan,

Just to share. Manage to find out what has caused to the problem. Via internal set-up, it was noticed that the tags belong to fieldbus are listed (in component table) but not in INtools (in index list nor in fieldbus tag browser list).

Run a sql to check the segment name of the missing tags in Segment Wiring browser. Take note of the wire_group_id. In my case, there are two records for the segment after the "copy unit" option is used. Somehow the "copy unit" duplicate the wire_group_id of the source database and hence the tags were not displayed.

Example in my case show of the 2 project (source and target) and the segment where the missing tags occur:

select * from wire_group where eng_proj_id in (525243, 525244) and group_name in ('S8','S9','S10','S11','S12','S13','S14','S15','S16') order by group_name;

Wire_Group_Id	Group_Name	Plant_Id	Eng_Proj_Id
538484	S8	520990	525243
574792	S8	84434	525244

select cmpnt_name, wire_group_id, eng_proj_id from component where wire_group_id in (538484,574792);

The result after the sql is executed (see below) where wire_group_id in the component table shows the same = 538484. Therefore another sql to correct the wire_group_id must = 574792 for eng_proj_id=525244 from the above result.

As a result, all the fieldbus tags that were missing from the Segment Wiring are now displayed.

This solution may not be applicable to other type of similar problem as it may differ slightly and may have other related tables to look at.

Hope it will benefit others. Thanks.
