DR18 Control digital outputs

8.18.1

Overview

If one or more digital outputs were defined in data record DR 7 for controlling using data
record DR 18 (see Assignment of digital output DQ.0, DQ.1, DQ.2, DQ.3 (Page 91)), this
output can be controlled using data record DR 18. Only outputs that were configured for
controlling using DR 18 (see Overview (Page 86)) are controlled based on the content of
data record DR 18. The set values are not saved in non-volatile memory!
In addition, transitions for the individual weighing steps 0 to 7 can be set in DR 18. With a set
(=TRUE) transition, the respective weighing step is not executed until the corresponding
transition is reset from TRUE to FALSE. The transitions are not saved in non-volatile
memory!
Procedure
● Check or adapt the desired parameter settings of the digital outputs in data record 7
● Specify the value for digital output DQ.0, DQ.1, DQ.2, DQ.3
● Transfer the data record to the scales
