IEC Operators and additional norm extending functions

 DMS 3.2 EN 02/2011 TD29 467

PLC Designer IEC operator: Bitwise OR of bit operands. The operands should be of the

type BOOL, BYTE, WORD or DWORD.

Example in IL:

LD 2#1001_0011

OR 2#1000_1010

ST var1 (* Result is 2#1001_1011 *)

Example in ST:

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

Example in FBD:

If you have a program step in the SFC like the following

and if you use 68xxx generators, please note the following: The allocation of the

value of the second input variable at the OR operator module to variable z will not

be executed ! This is due to the optimized processing in the SFC in case of value

FALSE at the input variable.
