DISPLAY_VALUE module
Any value (IEEE 754 floating point number), including status, can be cyclically transmitted via the
PROFIBUS master (Class 1) directly to the local display using the DISPLAY_VALUE module (slot 6).
Display value assignment to the main line, additional line or information line can be configured via
the local display itself or an operating program (e.g. FieldCare).
Output data
Status
The measuring device interprets the status in accordance with PROFIBUS Profile Specification
Version 3.0. The statuses OK, BAD and UNCERTAIN are indicated on the local display by a
corresponding symbol.

CONTROL_BLOCK module
By means of the CONTROL_BLOCK module (slot 7), the measuring device is able to process device-
specific control variables from the PROFIBUS master (Class 1) in cyclic data transmission (e.g.
switching on positive zero return).
Supported control variables of the CONTROL_BLOCK module
The following device-specific control variables can be activated by changing the output byte from 0
