Can't connect to controller

Robot Controller
1

I’m running into a strange problem when moving my code from RobotStudio to an IRC5 controller.

The code essentially just opens a TCP/IP socket and listens for incoming connections.

This code runs fine in RobotStudio, and apparently it runs fine on the IRC5 too - at least that’s what the FlexPendant is telling me.

The problem is that I can’t connect to the IRC5 controller via the network.

I know the controller is on the network, since RobotStudio shows the status of the controller, I can grant/revoke write permissions, browse files and so on.

It would be much appreciated if anyone could point me in the right direction.

EDIT:
Apparently there is a socket timeout a few minutes after the program starts. This happens regardless if I try to connect to the port or not.

Does the IRC5 system have the RobotWare Option “PC-Interface”? If not, you can connect to the controller via the service port.

Yes, it does.

I’ve tried connecting via the service port, same result.

Moved to RobotWare forum the problem is related to socket communication and not specifically RobotStudio.

Ok, I found the problem, I was listening on the wrong address.
127.0.0.1 works under simulation - it even accepts connections from remote hosts,
but on the controller the actual ip address of the interface must be used, otherwise the SocketBind call will time out.
