Hello, your problem is that the tension on the SENSE terminals of the WP321 is to low. If you have a 4 wire load cell you have to make two bridges, one between Exc+ and Sen+ and one between Exc- and Sen-. See also the manual chapter 6.2 image 6-2 https://support.industry.siemens.com/cs/ww/en/view/109738535 If you have already made the bridges there might be a wire break in the Exc or Sen wires.

Hello AutoGen, There exist no parameter in the WP321 module for the Nominal Output. You can connect load cells with a Nominal Outputup up to 4 mV/V.
