Hello Jurka; I am not quite sure I understand what the problem is with your setup. Let's see if I can provide some help. The DP/DP coupler is a special 2-slave Profibus module. Each slave in the DP/DP coupler must be connected and configured by a different Profibus-DP master, in their own project. And the configuration of each slave must be identical, but reversed... This last bit is described very well in the following FAQ: What are the special features of input/output addressing with the DP/DP coupler? https://support.industry.siemens.com/cs/ww/en/view/22327981 Basically: Input modules of slave 1 must be output addresses in slave 2, and output modules of slave 1 must be input modules of slave 2 on the DP/DP coupler. That is how the data is exchanged between the 2 masters. What you write to slave 1 (from master 1) is read by slave 2 ( transferred to master 2), what you read on slave 1 (by master 1) is the output of slave 2 (from master 2). I hope this clarifies your issues, if not, please take the time to write us again with more details (and screenshots of both configurations in each master. Hope this helps, Daniel Chartier |
