If setting values are defined for MINVAL and MAXVAL , Yx output signal does not
necessarily correspond to the displayed minimum and maximum values.
Example:
−
MINVAL1 is set to 20 °C.
−
The assigned input signals are 12 °C, 20 °C and 60 °C.
−
12 °C is displayed under MIN 1.
−
However, output signal Y1 is DC 0 V (because MINVAL = 20 °C).

Error handling

A check identifies available input signals after quitting the COMMIS
(commissioning) menu. We differentiate between two cases if one of the input
signals previously acquired is missing due to short-circuit or open circuit:
Case Description
1 At least 1 input signal is
missing, but calculation is still
possible.
2 At least 1 input signal is
missing, and calculation is not
possible.
The relevant input is not monitored if one of the input signals is missing after you
quit the COMMIS (commissioning) menu.
Section 5.4 describes how to handle errors of inputs Xx.
