– High limit – defines the measurement level above which the Hi state will be
displayed in the logical channel,
The current inputs parameters are:
– Name – each built-in input already has a name given by the device and the user
cannot change it, for the description of the Name parameter see Fig. 7.81 ,
–
Unit
– parameter which displays the measurement unit -
mA
,
– Mode – defines the measurement range,
– Low limit – defines the measurement level below which the Lo state will be
displayed in the logical channel,
– High limit – defines the measurement level above which the Hi state will be
displayed in the logical channel,
The NTC (temperature or resistance measurement) inputs parameters are:
For the temperature mode:
–
Name
– each built-in input already has a name given by the device and the user
cannot change it, for the description of the Name parameter see Fig. 7.81 ,
– Unit – parameter which displays the measurement unit - ° C ,
– Mode – defines the measurement mode (temperature or resistance),
– Low limit – defines the measurement level below which the Lo state will be
displayed in the logical channel,
–
High limit
– defines the measurement level above which the
Hi
state will be
displayed in the logical channel,
– NTC Equation – allows to choose the method of entering the thermistor
characteristic. There are two possibilities:
•
equation with the Beta parameter, where:
◦ A – resistance in reference temperature,
◦ B – β
25/100
parameter,
◦ C – reference temperature in Centigrades,
•
equation based on the Steinhart-Hart coefficients:
T =
1
A  B ⋅ ln  R  C ⋅ ln  R 
3
the measurement range which will be displayed is calculated based on the equations
above. In the second place
Low limit
and
High limit
parameters are taken into consideration
when determining the displayed range.
For the resistance mode:
– Name – each built-in input already has a name given by the device and the user
cannot change it, for the description of the Name parameter see Fig. 7.81 ,
– Unit – parameter which displays the measurement unit - Ω ,
– Mode – defines the measurement mode (temperature or resistance),
–
Low limit
– defines the measurement level below which the
Lo
state will be
displayed in the logical channel,
–
High limit
– defines the measurement level above which the
Hi
state will be
displayed in the logical channel,
