DR 30 current process values
8.19.1
Overview
Current states and process values in the scales can be monitored using process values and
advanced process values from data record DR 31. Monitoring selected data during
commissioning is extremely useful as it helps you to optimize parameters.
Procedure
● Read data record DR 30 cyclically or on a time-triggered basis
● Display/analyze the required tags
It is not always necessary to cyclically read data record DR 30. If the relevant process tags
are already selected in data record DR 14 (Page 106), they are immediately transferred via
the I/O interface. In this case, these tags and all status bits and messages are accessible
without data record communication.
