I receive a " TCP/IP Error 2741" popup message, when starting up my project.

This results in the project failing to startup.

This should only happen when two Network Interfaces are configured in the "network addresses form".  

Citect will fail to start if one of your configured network interfaces is un-available.  

Citect confirms this is an issue for CitectSCADA v7.0 and v7.1.

To workaround this problem, when you startup your project, you need to make sure all configured network interfaces are enabled and available.

Once the project has started, you can disable/disconnect one of them if needed (useful if you are using a RAS connection).

Citect is currently investigating the problem. Further information will be posted when available.
