jo2ham Posted May 26, 2015 Report Posted May 26, 2015 Hi everyone, I have a S7 1200 with profibus slave module. I want to connect this to S7 400H profibus network. I have added S7 1200 gsd file and configured in S7 400 system. But still Bus fault is there. Please help to configure S7 1200 as a profibus slave in S7 400H master system. Thanks in advance. Joshua.

Moggie Posted May 27, 2015 Report Posted May 27, 2015 (edited) Have you connected the S7 1200 to the profibus network? have you configured the S7 1200 PLC with the profibus parameters and downloaded them? have you set the profibus terminating resistor correctly? Edited May 27, 2015 by Moggie Quote
