hi Desi boyz,

I recommend you to have a look in this amazing manual:

CPU-CPU Communication with SIMATIC Controllers

page 96 will show you all posibilities for communication between S7-300 and S7-400. You can even see, which blocks to use.

hope this helps,

Hi,

if you will work with integrated PN-interface of you PLC you need TCON/TSEND... .

If you work over CP343-1 / CP443-1 you have to use AG_SEND/_RECV function.

On Industrie Online Support you will find examples to do that.

Dear Expert,

In addition to the existing query, we are using CP443-1 & CP343-1 Lean. And for communication between these station we are using Telemetry Wireless Tx/Rx. All station are pinging each other. 

I am using AG_Send & Ag_Rcv blocks. Will this work?
