2.5 Bitwise operators

The following bitwise operators are supported

Operator Symbol

AND &

OR |

XOR ^

NOT !

Both User or System variables can be used with these operators.

Examples:

V1 = V2 & 0xF ;clear all bits but lowest 4

IF (INPUTS & 0x3) ;check inputs 0 and 1

V1 = V1 | 0xff ;set lowest 8 bits

V1 = INPUTS ^ 0xF ;invert inputs 0-3

V1 = !IN_A1 ;invert input 0

2.6 Boolean Operators

These operators are used in logical expressions.

Operator Symbol

AND &&

OR ||

NOT !

Examples:

IF APOS >2 && APOS <6 || APOS >10 && APOS <20

. {statements if true}

ENDIF

Above example check if APOS(actual position) within one of two windows:

2 to 6 units or 10 to 20 units. In plain English:

"If APOS more then 2 AND APOS less then 6 OR APOS more then 10 AND APOS

less then 20 -----à then evaluate to TRUE. Otherwise it is FALSE"

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 71 72
