Cause
An additional connection that has not yet been assigned to a daisy chain was placed within a net in the schematic. The additional connection contains a copy of a component that is part of the net. The copying process duplicates the ID for net-based connections.
Example:A net N1 in the schematic connects 5 fuses (-F1 to -F5) with the potential L1. The connection points form the following daisy chain:
|
Connection point |
Source |
Target |
|---|---|---|
|
L1 |
L1 |
-F1:1 |
|
-F1:1 |
-F1:1 |
-F2:1 |
|
-F2:1 |
-F2:1 |
-F3:1 |
|
-F3:1 |
-F3:1 |
-F4:1 |
|
-F4:1 |
-F4:1 |
-F5:1 |
|
-F5:1 |
|
|
Another fuse -F6 is placed within the net in the schematic with a T-node by copying and renaming fuse -F5.
When the connection is inserted, the daisy chain remains unchanged as the connection point -F6:1 has not yet been assigned to the daisy chain.

When the fuse -F4 was copied, the ID (identification number) for the net-based connection was copied as well, so there are now two identical identification numbers "8" in the net.
Solution
Integrate the copied connection into a daisy chain.
For the above example, the steps are as follows:
- Locate the relevant net definition point in the schematic using the Go to (graphic) function from the popup menu in the Message management dialog.
- Open the Properties <...> dialog for the net definition point.
- Bring the Net connections tab to the front.
- Identify the added connection point in the Connection points table.
Note:When you open the Property dialog, duplicate IDs for net-based connections are no longer displayed in the Connection points table - only unique IDs. In our example, fuse -F6 is automatically assigned ID 9. In fact, the IDs are still duplicated (ID 8).
The fact that -F6 was added can be seen from the value 0 under Number of targets in the Connection points table.
- Add the connection point to the daisy chain by clicking
(Create daisy chain) and highlighting -F6:1 in the Connection points table.
Connection point -F6:1 is copied to the Connections table and entered beneath the horizontal line of the daisy chain. This creates a new daisy chain. - Click
(End daisy chain) to complete the daisy chain. A horizontal line is created beneath connection point -F6:1 in the Connections table. - Select connection point -F6:1 in the new daisy chain, then click the
(Move up) button to move it to the first daisy chain under connection point -F5:1. This breaks up the second daisy chain. - Click [OK] to close the Properties <...> dialog for the net definition point. The duplicated IDs are automatically removed and the new connection is integrated into the daisy chain for the net.
- Then start a new check run.
