Have a issue with an S7. Although the PLC goes into run mode, the yellow bus communication LED is blinking and the whole HMI display is frozen.

Any idea what is happenning?

Please describe the network you have first , or if you are able , copy what is in the diagnostics buffer and post.

What are you calling the Bus LED as far as I am concerned Bus LED on S7 PLCs are RED, do you mean the RX LED on Ethernet cards?
