12.4.5 MUX

Multiplexer

OUT := MUX(K, IN0,...,INn)

means:

OUT := INk.

• IN0, ... , INn and OUT canbeofanytype.

• K must be of type BYTE, WORD, DWORD, SINT, USINT, INT, UINT, DINT or UDINT.

• MUX selects the Kth value from a number of values. If K is greater than the number of other

inputs (n), the last value will be passed on (INn).

Examples

IL ST FBD

LD 0

MUX 30,40,50,60,70,80

ST Var1 (* Var1 = 30 *)

Tip!

For runtime optimization, the system now computes the expression attached to the input side of

INk. Contrary to this, simulation computes all branches.

12.5 Comparison operators

Types:

The operands of the following comparison operators can be of type BOOL, BYTE, WORD, DWORD,

SINT, USINT, INT, UINT, DINT, UDINT, REAL, TIME, DATE, TIME_OF_DAY, DATE_AND_TIME and

STRING.

12.5.1 GT

Greater than

A Boolean operator with the result TRUE if the first operand is greater than the second operand.

Examples

IL ST FBD

LD 20

GT 30

ST Var1 (* Var1 = FALSE *)

Var1 := 20 > 30;
