5.18 DR 27 Internal process value 2 (AWI)
Other current internal states and data can be read in the scale using process value
2 (only with SIWATOOL FTA). Their meanings are directly related to the internal
processing in the firmware cannot always be interpreted from an operator's
viewpoint.
Observing selected data can be helpful during servicing however, for understanding
the behavior of the system. DR 27 cannot be sent to the SIWAREX FTA.

0 = SIMATIC operation activated
1 = Stand-alone operation activated
Bit 1 recording from dig. Load cell
0 = Recording stopped
1 = Recording activated
Bits 2 to 7 unused
0 Current tare weight process value
0 Current tare-average value (when taring with
average value)
0 Zero set value (is set during boot if ‚Switch-on zero
setting' is activated)
0 Zero set value (is set with zero setting)
0 Zero point correction value, which is influenced by
the automatic zero adjustment
0 Impedance reference value
0 Current impedance value from the last
measurement
0 Last largest weight value
0 Load counter for the operating minutes since the
last default value
0 Load previous maximum inner temperature since
last default value [0.1°C] If no temperature value
exists: -100.0°C.
