Hello Fikrr; The screenshot you show us shows a valid Profibus-DP configuration for your scale. It also shows that the data (IN and OUT) is taken as a single consistent telegram, "4W consistent" for both lines in your I/O table. This will require that you use SFC 14 "DPRD_DAT" and SFC 15 "DPWR_DAT" in your PCS 7 program See the entries for these functions in the System and Standard Functions manual: https://support.industry.siemens.com/cs/ww/en/view/109751826 These SFCs were developed for use with Simatic Manager and Step 7 v5.x.For information on their use with PCS 7, look at these pages from the PCS 7 V9.0 SP1 Manual Collection https://support.industry.siemens.com/cs/ww/en/view/109759321/113683549835 CPU 41x–H as PROFIBUS DP master https://support.industry.siemens.com/cs/ww/en/view/109759321/31144120715 Consistent Reading and Writing of Data from and to DP Standard Slaves/IO Devices https://support.industry.siemens.com/cs/ww/en/view/109759321/113683549835 Hope this helps, Daniel Chartier |
