8.11.3
Load cell characteristic value
The load cell characteristic value is required to correctly interpret the output voltage from the
load cell. When Siemens WL series load cells are used, the exact characteristic value can be
read from label on the cell. If the exact characteristic value of the utilized cell(s) is not
available, a rounded value can also be specified. For scales with multiple load cells, the
average of all load cells must be calculated and entered.
Example
Characteristic value according to load cell label = 2.018 mV/V
→ Characteristic value = 2.018 mV/V
If this exact value is not known, 2.0 mV/V could also be entered.
8.11.4
Rated load of a load cell
The nominal load is entered in the specified weight units The parameter is required for
automatic calculation of the scale characteristic curve (command 82).

Overview
Before the SIWAREX module can be integrated into an Ethernet network, the Ethernet
parameters must be adapted, if necessary. The IP address, subnet, gateway and device
name can be changed or adapted in DR 12.
