In our example we do not use
this function, so the display
has been included for your
information only.
The name of the function may be
xx and further down in the display
the alarm texts may be entered.
The values "Min. and Max.
Readout" are your settings
representing the lower and upper
values of the voltage range. 2V
and 10V, for example. (The voltage
range is selected during the I/O
setup).
The controller will reserve a
relay output in the I/O setup.
It is not necessary to define
this relay if all you require is
an alarm message via the data
communication.
In our example we do not use
this function, so the display
has been included for your
information only.
