Hello

I had 2 S5-155 Plc's communicating with CP525 protocoll 3964R. One of the S5-155 is using Fecth and send functions. The other uses the send-all receive-all functions.
Now we are substituing one of the S5-155U fou a S7-400 and the correspondeing CP525 for a CP341.
My question is. In the s7-400 I must use the SFB12 and SFB13 to send and receive data from the partner. Which parametres must I have to introduce in the blocks to creat the send-all/receive-all mechanism (like uin the S5)?)
