6.2.6
Concrete example
To explain the above-mentioned paragraphs, the sequences of instructions to be
transferred to the module and the corresponding answers of the module are listed in
the following at a concrete example. The case without errors is treated.
The module variable zk_umin_g is to be read-out and a new value is to be stored in it.
The corresponding code is "zn", the old value in the variable is "+3500" and the new
value is "+3600". This results for the two ASCII modes in the following communication
with the module:
