I dont have any simatic hardware to check my work, becuase all the hardware is delivered at project site.I want to confirm that whether i am going on the right path or not. Please read my query and reply will it work or need any correction. Hardware of my project: 1) CPU 315-2 PN/DP, (2) IM 153-1 (3) Siwarex U-2 7MH4950-2AA01 Following are the steps mentioned below, which i need to confirm. I have chosen this method because i want to make my project as simple as possible: I have Siwatool U software from where i want to do callibration and other necessary settings, I am not using any step7 programming for callibration and other settings. From hardware configuration i have selected communication type SFC.SFB, FB communication. Please see attached pic *In step7 software, I have programed a FC in which SFC14 is called for fetching data from siwarex U channel. I also make a UDT as temp variable, the UDT data type is defined according to Siwarex U Manual. Please see the attached pics for programmed FC and UDT contents in my next post below.

Best regards Siwarexi

Best regards Siwarexi Hello Siwarexi I have the S7 example programm “SIWAREX_U_GETTING_STARTED_S7.zip”.But i dont want to use this program because if i can set parametesr of siwarex module with SIWATOOL 2 U software then i only need to extract values of gross weight and fault as mentioned above in my post. With this program it looks to me i have to consider many other aspects as well. Thanks

Best regards Siwarexi

Use the start addresses of the Siwarex U modules into the Hardware Config to find out the weight values: - Channel 1: Pheriphery-Inputword (x + 2) - Channel 2: Pheriphery-Inputword (x + 10) “x” means the start address into the Hardware Config of the Siwarex U module. Best regards Siwarexi
