I have a panel pc running Win7 with Wincc Flexible 2008 SP5 runtime. I have configured "RT load" to autimatically start up my hmi application. It all seems to start up well but no tags are beeing updated by the plc. Only ##### shown and no statuses are being updated. To get the communication up and running I need to manually go out of runtime and start it up again. The the communication will start up as expected. Anyone have any suggestion for this fault? I have tried to ping the plc from the panel pc when Wincc in not communicating and the network card works well.
