DR 30 Process state

8.27.1

Overview

This data record contains all weight values and related status information of WP251. All
values are read-only.
Note
Data record DR 30 does not have to be read into the PLC via a command! In data record DR
14 (page 101), the user can select two process variables that will be transmitted
automatically via the S7-I/O to the CPU and be available there. In addition, the AWI
((Automatic Weighing Instrument) Status is available cyclically in the I/O (see section
"Integration in SIMATIC") and can thus be directly used in the PLC program. At the Modbus
end, the parameters and status information from DR 30 is always current and the registers
can therefore be read immediately.

Note
In removal mode there is not
enough material in the contain-
er at the start of dosing (gross <
set point) Dosing can still be
started in this case with the
"Continue weighing" command
and ended using "Rest empty-
ing" as soon as no more mate-
rial can be removed from the
scale.
