7 Configuration
7.16 Math
The optional math function (extra code 260 "Math/Logic") supports formulas which can be freely used
for mathematical calculations (analog values).
In addition, functions for calculating the differential, ratio, and relative humidity are also provided. In this
case, two analog values (variables a and b), for example, the measured values of analog input 1 and 2
are linked to each other. The dry-bulb temperature and the wet-bulb temperature are required for calcu-
lating the relative humidity and should be determined with a psychrometric humidity sensor.
There is also a function for calculating a floating average.
The results are available in the analog selector. If the function is not active, the math value = 0.
A digital signal (0/1) is also derived from the results in each case. This is 0 when the result is a valid
value.
Activating the function
On the device, the math function is only available when activated. To do so, the extra code "Math/Logic"
must first be activated in the setup program using an activation code (Setup program: Online parameters
> Enabling of extra codes).
The math function is available in the setup program after enabling the "Math/Logic" option (Configura-
tion: Basic device > Math/Logic).
