(0)  Hello Mitish; The installation of the DP/DP coupler is relatively simple. In each masters' Profibus configuration setup a DP/DP coupler slave. In Step 7 the GSD file should already be loaded, so you should find it in the Gateway section of the Profibus catakog. in HWConfig. For the RX3i configurator you will probably need to import the GSD file and install it in the configuration software (look in your online hel^p to find the procedure): PROFIBUS GSD files : LINK   Next, in each configuration, setup the data exchange areas that you want to exchange between the 2 DP networks. It is very important that the data exchange areas match in size, but they must be opposite: the outputs of the RX3i slave must become inputs to the S7-300 master, and vice-versa. This is explained in the following FAQ: What are the special features of input/output addressing with the DP/DP coupler? You will also find in the FAQ a link to the DP/DP oupler manual, which could be of aid. Hope this helps, Daniel Chartier
