DP-DP Coupler communication

s_vb Posts: 257 Rating: (1)	Hello Sir, Sorry last time I asked wrong question. I am doing communication between CPU 317-2 PN/DP and IM 151-7(with DP master) using DP-DP coupler. I have question that do I have to configure IM151-7(with DP master) in my hardware configuration or in program? I am doing this communication for the first time using DP-DP coupler.I want to sent and recieve data to IM151-7. Is there any need to use blocks "DP_SEND" and "DP_RECV" as both are master systems. Only by configuring hardware of DP-DP coupler (bytes to be sent) and by setting address(profibus) of DP-DP coupler will data be send and recieved.? Please clarify these things to me. Thanks Shailesh

For more informationtake a look in this FAQ Rgds, Marciano
