Dear Experts,

I am trying to make a communication using put/get.

My situation is like below,

-All software already made with simatic manager V5.6 in differen S7 project and i can modify just one of them which will be use local CPU for S7 connection.

-Local CPU is S7300 (6ES7 314-6CH04-0AB0) and it communicates profinet using CP 343-1 card (6GK7 343-1EX30-0XE0)

-Partner CPU is S7300 (6ES7 317-2FK14-0AB0) and it has integrated ethernet port.

What i have tried up to now;

-I have built unspecified S7 connection, configured IP,port data correctly.

-I have downloaded this S7 connection with NetPro .

-I can go online for hardware and program blocks for both CPU.

-I have used FB14 block one by one from communication blocks,system function blocks in standard library and simatic.net CP300 blocks. None of them worked. On the block there is no Error,NDR and Status signal. All of them are zero.

-I made another configuration to test my way with two CPU's which have integrated ethernet port. I can communicate with get function from both side using unspecified S7 connection.

Is there any point to pay attention for CP card communication.

Thanks  

Hello Alikol

here you can check the existing ways of communication with integrated interfaces and CPs:
