For module 3:
The Mass Flow Meter is also making use of the special identifier byte after
which one of the two I/O configuration possibilities can be sent.
For module 1:
For module 2:
In case of a configuration tool, e.g. STEP7, see the example below.
Using STEP7, one can make a selection from one of the modules that are
declared in the GSD file. When selecting the slave type from the configuration
tool, see [1], this folder can be picked up and dragged into the PROFIBUS DP
master system rail [2]. The next step is to select one of the modules [1]. Here
the ‘maximum configuration’ is picked up and dragged into the slave module
slot [3]. Now the slave configuration is done and can be saved, compiled
downloaded into the S7 controller.
