Hello everyone,

I have two 315-2 DP software redundancy connected to S7 1200  (tia portal V.13 sp1) via profibus dp & a 1242-5 slave module. A KTP1200 HMI is connected to this S7 1200. But i am not able to send the hmi data from the s7 300 to s7 1200. i am able to send data from s7 300 (tia portal) to s7 1200 (tia portal), but when i do with simatic to tia portal it is showing error. I have attached my configuration below. Can anyone help me with any sample programs on how to configure this connection without a CP. First, is it possible without a CP?

Hello,

how you did cfg in Step7 v5 to S7-1200 with DP Slave module?

Hello,

how you did cfg in Step7 v5 to S7-1200 with DP Slave module?

 Thank you for your response.
I established connection now based on the below attached manual. but still i'm not able to move any data from 1 plc to another. Can you please tell me if it is possible to establish data transfer in my configuration as per the attached manual.
When i force value to the output address of master, it is not received in the slave input address.
Now i'm researching on DPRD_DAT & DPWRT_DAT blocks. Any other suggestions?

Hello,

if you have CP, you need use that instructions.

hi draacula,

no, he says: IF you have...

 I´m a little bit confused. you´re saying that you want to communicate from S7-1200 to S7300 and you´re posting a manual from CP1542-5.

please make precise information about the used HW and how you want to comunicate.

If you want to comunicate over Profibus with S7-1200, you need a CM1242-5 for S7-1200 as slave or a S71243-5 for S7-1200 as master. Have a look on  page 134 of the manual you posted.

hope this helps,

regards,
