VC10CollVal

V = Variables

C = Calculation functions The VC10CollVal function sets a result on a variable (resul) on the basis of the value from a variable than other 2.
The function follows the following truth table:

Truth table

val01 > val02

result = 0

All subsequent cases relate to val01 ⇐ val02 and analyze only Val03

val03 < val01	result = 1
val01 ⇐ val03 < valore2	result = 2
val03 >= val02	result = 3

IMPLEMENTATION

VC10CollVal (val01, val02, val03, Result)

Parameters:

IN/OUT	VARIABLE TYPE	EXAMPLE NAME	DIM
IN	SYSTEM	val01	L/S	First value to compare
IN	SYSTEM	val02	L/S	Second value to compare
IN	SYSTEM	val03	L/S	The value to compare with val01 and val02
OUT	SYSTEM	result	B	Variable containing the result of the comparison according to the truth table shown above

Example

Run the comparison when the “gfComp” flag is set to 1.

IF gfComp
	gfComp = 0
	val01 = 1000
	val02 = 5000
        VC10CollVal (val01, val02, val03, result)
ENDIF

Note

The function execute a WAIT a time every 180 milliseconds
