Cause
You have placed a plug connection with separate male pin and female pin representation in the schematic. A corresponding symbol with a direct connection point was used for male and female pins. At least one more male pin was connected with a female pin or at least one more female pin was connected with a male pin on the direct connection resulting from this. The direct connection becomes graphically visible in the schematic as an autoconnecting line in case of a larger distance between a female pin and a male pin.
A direct connection exists between male pins of the plug -X2 and female pins of the plug -X1. The two male pins -X2:1 and -X2:2 are connected with the female pin -X1:1 via a T-node. In addition both female pins -X1:2 and -X1:3 are connected with the male pin -X2:3 via a T-node. An error message is output for both cases.
Solution
- Delete the surplus pins so that only one male pin each is connected with a female pin of the plug via a direct connection and this way a unique male pin / female pin contact pair can be formed.
- Update the connections.
- If required, start a new check run.
