Hello

I first time configure Profibus communication.

I configured the profibus slave card CM1242-5 as shown on "Profibus Adresses". I created a data block (DB110) with vary data types (Bool and Int). How can I transfer all data from DB to Profibus outputs Q68-Q307. I was tring to use MOVE_BLK and MOVE_BLK_Variant but I didn't succseed.

Thank you in advance for support

As I know profibus is working wih IP adresses of modules.

It would be nice to know more about your project.

What devicec except S7-1200 are in profibus net? Does S7-1200 - main PLC and others are sensors and field mechanisms? ets.

Do you configured profivus network and imported gsd files in your project?

In the Profibus network is only my PLC and Client's device, For now I don't know what the device will be on Clinet's side. Moreover my PLC (as master) is communicating with 3 others PLCs (as slaves) via Profinet but this side of the project is checked and it's working properly. The Master PLC is taking data from slaves ones and exchange data with Client's device (probably PC with SCADA). I need to know how "send"  data from Data Block (with vary types of data) to Profibus outputs declared in "Transfer area" of CM1242-5 card. I can send them one by one for example Bool type DB110.DBX0.1 = Q68.1  and Int type by MOVE instruction. But I would like to do this with using only a few instructions instead of hundreds of code lines. Please find as an enclosure declaration of data in DB110. "DM_Stany " is a block of Bool data as well as "DM_Info" and "DM_Cmd"

Thak you in advance for replay

 Hello JAcek_mat,

You can use WRREC function, just for the input ID choice hardware identifier of your CM1242-5.

Take a look picture, in my case hardware identifier was ""Local~HSC_1""

Hi Jacek_mat,

Any luck with this? I am trying to achieve the same thing, however, S7-300 PLC.

This example works for your case as well:

WRREC is SFC58 WR_REC in s7 classic simatic manager,

New question published by PWNZ22 is split to a separate thread with the subject Profibus - writing data (from DB) to Profibus outputs (Q) S7-300.

Best regards
