Siemens SIWAREX FTA - DR 30 - Totalising Memory 2

Weighing Functions
SIWAREX FTA
5-114
5.19.12 DR 30 - Totalising memory 2
The momentary value in totalising memory 2 (numeral step from DR3).
5.20 DR 31 Process values 2 (NAWI, AWI)
The current states and data in the scale can be monitored using process values 1
and 2.
Observing the selected data is very helpful in test operation for optimising
parameters. In addition, if the SIWAREX FTA is controlled by the SIMATIC CPU
then the status can also be observed.
