Hi,

I have a S7 315-PN/DP as master cpu for a line and we have a new application with a S7 1200 CPU V4.1

I marked the box for get/put communication

And the IP adres is in the same range

I can go online in both cpu's

The Cpu are in separate projects both in TIA V13 SP1

And i don't want to do any changings in the s7 1200 cpu

So i want to use a GET block with an unspecified connecton (I did this before once with TIA and S7 V5.5)

I'm using the GET block (not the GET_S) and i want to get IW0 and QW0 from the S7 1200 cpu and transfer this to a DB10.DBW0 and DB10.DBW2

I transfered this but nothing works

I used the wizard to set up the connection, in the connection i had to insert only the IP adres from the S7 1200 an TSAP 03.01

When i am online the connection turns red because it doesn't work

hi,

can you post a screenshot of your block-call?

regards,

HI dendhodt,

I have got a Entry for you with same requirements:

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?

I can imagine that this can help you.

Good Luck

Hello 

please check below link similar topic which can help you

all the best 

I already looked at the manuals but didn't found anything i forgot

But today i looked at the connection again and changed it to 3.01 (was switching between 10.01 and 3.01 becaus it didnt worked) and after this i transfered the project to the cpu  and everything worked

The marking from the connection turned green :)

It turns out i didnt transfered the project (hardware i think to) to the cpu

But thanks for the help.
