Data structure
Input data of Discrete Input
Byte 1 Byte 2
Discrete Status
DO module (Discrete Output)
Transmit discrete output values from the PROFIBUS master (Class 1) to the measuring
device. Discrete output values are used by the PROFIBUS master (Class 1) to enable and
disable device functions.
The DO module cyclically transmits the discrete output value, along with the status, to the
measuring device. The discrete output value is depicted in the first byte. The second byte
contains standardized status information pertaining to the output value.
Three Discrete Output blocks are available (slot 17 to 19).
Assigned device functions
A device function is permanently assigned to the individual Discrete Output blocks.

Discrete Status
EMPTY_MODULE module
This module is used to assign empty spaces arising from modules not being used in the
slots .
The measuring device works as a modular PROFIBUS slave. In contrast to a compact slave,
a modular PROFIBUS slave has a variable design and consists of several individual
modules. The GSD file contains a description of the individual modules along with their
individual properties.
The modules are permanently assigned to the slots. When configuring the modules, it is
absolutely essential to observe the sequence/arrangement of the modules. Any gaps
between the configured modules must be filled with the EMPTY_MODULE.
