FB_BA_MultiCalc_XX

Functional description

In activate state (bEn=TRUE), the function block determines the following from the 8 input values udi01...udi08:

• the maximum value of all inputs udiMax
• the input at which this maximum value is applied udiMinActv
• the minimum value of all inputs udiMin
• the input at which this minimum value is applied udiMinActv
• the average of all inputs rAvrg
• the sum of all inputs rSum
• the difference between the maximum and minimum value udiDiff

If not all inputs are to be calculated, the number can be limited by an entry at udiNum: with udiNum=6, for example, the calculations are only performed for the inputs udi01...udi06.
An entry greater than 8 is automatically limited to 8, an entry less than 1 is automatically limited to 1.

Example:

If bEn = FALSE, 0 is output at all outputs.

VAR_INPUT

bEn    : BOOL;
udi01  : UDINT;
udi02  : UDINT;
udi03  : UDINT;
udi04  : UDINT;
udi05  : UDINT;
udi06  : UDINT;
udi07  : UDINT;
udi08  : UDINT;
udiNum : UDINT;

bEn: activation of the block function

udi01...udi08: input values from which to calculate.

udiNum: number of input values to be used for the calculation.

VAR_OUTPUT

udiMax     : UDINT;
udiMaxActv : UDINT;
udiMin     : UDINT;
udiMinActv : UDINT;
rAvrg      : REAL;
rSum       : REAL;
udiDiff    : UDINT;

udiMax: maximum value of all inputs

udiMaxActv: input to which the maximum value is applied.

udiMin: minimum value of all inputs

udiMinActv: input to which the minimum value is applied

rAvrg: average of all inputs

rSum: sum of all inputs

udiDiff: difference between the maximum and minimum value
