Hi Serge,

I'm trying to communicate 2 PLC, The first one: S1500 & the second one S400. But, till today, It doesn't communicate. How you set the parametisation in both PLC? DO you have any sample of that communication (BSEND & BRCV) S400-S1500? I need to know what is the procedure to do.

Thanks

Hi ICOMR, did you get this to work?

I'm facing same challenge, S7-400(step7 V5.5) <> S7-1500(tiaportal) BSEND/BRCV communication.

It think I have everything correct but communication wont work?!

Hi Kicken

I am facing the same problem.

They only way I could get the Ethernet comms between a 1500 and a S7 Classic 400 working was to use PUT/GET in the 1500 program.

I did try using TCP instead of S7 Connection with the BSEND/BRCV, but on the 400 side there was an error that the 1500 was "locked".

Hope this helps.
