5.6.4 Function DEVIAT
Availability Standard on all models
(A/B – 1) * 100 %
Formula
Calculation of the deviation rate between two process variables.
Use
→ To set the parameters of the function, refer to section 9.14.
5.6.5 Function MATH
Availability Optional (see section 9.5)
Formula The function "MATH" permits to enter an equation which respects the following rules:
- up to 125 characters;
- up to 5 process variables A, B, C, D, E.
- with the operators and priority rules given in Table 2.
Table 2: Operators, priority and calculation sequence of the MATH equation
→ You can enter multiplications without the operator, e.g.
10A/5(B3) = 10xA/5x(Bx3) = 6xAxB
→ See also section 8.5 Entering a mathematical equation.
→ To set the parameters of the function and have some examples of use, refer to
Use
section 9.14.
