Hi. I use satelline 3AS modems for wireless link between two simatic stations S7300 with cp343-5 and s7400 with cp443-5. They both are configured as master at 9600kbps. like here

this connection work correct, but sometimes cp443-5 is still transmitting data and cp343-5 signaling BUSF. Then i must (at this same time) restart both of modems. I'll be grateful for some advice. Thanks.
