scanner problem, could not find controlle

Developer Tools
1

Scanner = new NetworkScanner();

Scanner.Scan();

Scanner.Controllers.Count // the count here is 0 for production machine.

When I execute the above code, then the software can’t find the robot controller. This is only not working on the production machine. If I use the development machine it works fine. on both machines is the following software installed: Robot Application Builder 5.08 and Robot Studio Online 5.08 and .Net 2.0. On the development machine is installed visual studio 2005.

The developement machine and production machine are connected through the service port. Connection through the Lan connection makes no difference.

This could be a firewall problem on your production machine. The firewall must be configured to let the process “robnetscanhost” (aka “ABB Industrial Robot Discovery Server”) both access the network (UDP port 5512) and accept connections (UDP port 5513).
