MUX
Multiplexer
OUT := MUX(K, IN0,...,INn)
means:
OUT := INK.
IN0, ...,INn and OUT can be any type of variable. K must be BYTE, WORD, DWORD, SINT, USINT, INT, UINT, DINT or UDINT. MUX selects the Kth value from among a group of values.
Example in IL:
LD 0
MUX 30,40,50,60,70,80
ST Var1 (* Result is 30 *)
Note that an expression occurring ahead of an input other than INK will not be processed to save run time! |
