12.2.2 OR

Bit-by-bit OR of bit operands

Examples

IL Var1 : BYTE;

LD 2#1001_0011

OR 2#1000_1010

ST Var1 (* Var1 = 2#1001_1011 *)

FBD

ST Var1 := 2#1001_0011 OR 2#1000_1010

Note!

Make sure to observe the following when using 68xxx or C-code generators in the FBD for the

illustrated program sequence.

As soon as the input variable a assumes the value TRUE, the assignment of the value of the second

input variable at the OR operator organization unit to the variable z will no longer be performed as

a consequence of the optimized processing procedure within the FBD.

12.2.3 XOR

Bit-by-bit XOR of bit operands

Examples

IL Var1 : BYTE;

LD 2#1001_0011

XOR 2#1000_1010

ST Var1 (* Var1 = 2#0001_1001 *)

FBD

ST Var1 := 2#1001_0011 XOR 2#1000_1010

12.2.4 NOT

Bit-by-bit inversion of a bit operand

The operand should be of type BOOL, BYTE, WORD or DWORD.

Examples

IL Var1 : BYTE;

LD 2#1001_0011

NOT

ST Var1 (* Result = 2#0110_1100 *)

FBD

ST Var1 := NOT 2#1001_0011
