At WDC_SEND block of first station you have to enter the Remotestationaddress (target address) of the second station. And the receive buffer of second station should match with send buffer of first station. Have a look to this FAQ, which describe what I mean. How can you ensure that all data sent from an S7-200 via GPRS is received? hope it helps regards

So please search a non-used bit in send-block and enable this bit if Q0.0 is "1". At second station the same bit should now be "1" if message was sent. regards
