Sending variable from S7-200 to S7-300 via EM277

Hello people,

I have established communication between a S7-200 and a S7-300 via profibus DP using an EM277 module. The network is well configured and i´m using a 32 Bytes Out / 32 Bytes In configuration on the module. I am able to send the bytes i need, but i also need to send one Double Word variable. How can i do that ? Suggestions?

Thanks in advance,
