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 line 1 or line 2 can be configured via the local display itself or an
operating program (e.g. FieldCare).
Output data
Status
The status is not evaluated by the device.
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

x:
!
Note!
The control (e.g. switching on positive zero return) is executed by cyclic data transmission if the
output byte switches from "0" to the bit pattern in question. The output byte must always switch
from "0". A switchback to "0" does not have any effect.
