Figure 33 : Arithmetic functions
The functional block is used to calculate the image using one of the arithmetic functions available for 2 variables,
A and B, selected from the process variables available. Variables A and B must be of a kind and in identical units.
Moreover, A and/or B may be the result of a function already used:
function calculation made
A+B Sum of 2 variables, A and B
A-B Subtraction between the 2 variables, A and B
A/B Ratio between the 2 variables, A and B
A/B[%] Passage rate
(1 - A/B)[%] Rejection rate
(A/B - 1)[%] Deviation rate
Once the function has been configured and activated, the result "Fx:" calculated is available in the list of
process variables on the "M0:MAIN" board. This list appears in the output configuring, user view config-
uring and datalogging menus to:
• Assign the result "Fx:" calculated to a physical output (analogue, AO, or digital, DO) (see chap. 8.10.22
and 8.10.22).
• Display the result "Fx:" on one of the user defined "Ux" views: see chap. 8.10.8.
• Logging the values of "Fx:" using the datalogger: see chap. 8.10.18.
Refer to chap. 8.9 to access Parameters menu.
