8.14.7 Refresh counter for process values
Measured values are calculated every 10 ms in the SIWAREX module. A counter is
incremented by 1 each time. Once the counter reaches the value 65536, it starts again from
zero. The counter can be used as a time stamp for data record DR 30.
8.15 DR 31 advanced current process values
Current states and process values in the scales can be monitored using advanced process
values and process values (DR 30). This data is not required for standard operation of the
scales.
Monitoring selected data during trial operation is extremely useful as it helps you to optimize
parameters.
Procedure
● Read data record DR 31
