Hallo Guys,

I have a problem with FB321. I downloaded the sample program from Siemens website in which the Version of FB321( used for Communication with WP321) is V4.0. I would like to use SIWAREX DB junction box. For this, i need to define some parameter in DR70 of FB321 which is NOMINAL LOAD OF ALL LOAD CELLS. This parameter is not available in the instance DB of FB321. In TIA portal, the FB321 used is having V4.6 which has this parameter in DR70. Can anyone help, if FB321 above V4.0 is also available for Classical Step 7?
