Hello ,

I have in my TIA PORTAL V13 sp1 project two CPUs (S7-314C-2DP with CP343-1 and S7-1215C) and i want to send analog valve from s7 300 to 1200  through ethernet

I can go online simultaneously from TIA PORTAL V13 sp1 to both CPUs and program them but i am not able to send  data between them using  PUT block as in example i use PUT only on S7-300-side only but fail to send data  

Can anyone help me?

How do you configure and program an S7 connection and the FB15 "PUT" and FB14 "GET" function blocks for data transfer between an S7-1200 CPU and an S7-300 CPU?

Regards

Hi,

did you execute documentation step for step?

The PUT/GET instructions have status - word and error - bit. You could check this.

Please also check the manual

CPU-CPU Communication with SIMATIC Controllers

hi,

do you have "CP343-1" or "CP343-1 lean"?

with CP343-1 lean, PUT/GET-communication is only possible with S7-300 as server. You have to use the blocks in the S7-1200-CPU.

See the manual Towome posted on page 97

hope this helps,

regards,
