ONFIGURATION
Math and logic module
Special controller types (differential, ratio, humidity, C-level controller) or
mathematical formula and logic combinations are configured here.
C-level control and math/logic formula (math and logic module) are extras.
The results of the calculations can be called up, under the variables “Math X”
(math formulae) and “Logic X” (logic formulae) (X=1 — 8).

Range start
- 1999 to + 9999 Definition of a value range for the result of the mathematical calculation.
If the value range is exceeded, an out-of-range condition will be signaled.
Range end
- 1999 to + 9999 Definition of a value range for the result of the mathematical calculation.
If the value range is exceeded, an out-of-range condition will be signaled.
Linearization
Linear The mathematical calculation can be combined with a (customer-specific)
linearization table.
