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.
Example (change the output byte)
Output data
EMPTY_MODULE module
The measuring device is a so-called modular PROFIBUS slave. In contrast to a compact slave, the
structure of a modular slave is variable - it consists of several individual modules. In the GSD file,
the individual modules are described with their individual properties. The modules are permanently
assigned to the slots, i.e. the sequence or arrangement of the modules must be observed when
configuring the modules. Gaps between configured modules have to be assigned the
EMPTY_MODULE module.
