Re: IEC 61131-3
LD N Make current result equal to the operand
ST N Save current result at the position of the Operand
S Put the Boolean operand exactly at TRUE if the current result is TRUE
R Put the Boolean operand exactly at FALSE if the current result is TRUE
AND N, ( Bitwise AND
OR N, ( Bitwise OR
XOR ( Bitwise exklusive OR
ADD ( Addition
SUB ( Subtraction
MUL ( Multiplication
DIV ( Division
GT ( >
GE ( >=
EQ ( =
NE ( <>
LE ( <=
LT ( <
JMP CN Jump to label
CAL CN call function block
RET CN Return from call of a function block
) Evaluate deferred operation
