S7300 Ethernet comm's

Hey all,
I’m kind of spinning my wheels a bit with this one. I need to exchange data between to S7-315 PN/DP’s .
I need to send a couple of Bytes (bits) and 6 Reals each way. So I was thinking of using a couple of FB12 “BSEND” and FB13 “BRCV” to do the job because of the Ethernet CPU’s.

I had a look at the example from the Siemens support site and seemed as simple other than it shows only an array (length of 10) Bytes being moved. How can I move or mix all my data one way with one BSEND and BRCV?

Thanks for any input.

Where are you declaring your array of bytes to be sent, global DB or static data ?
