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.
