With all logical operands and some hints? Classical KUKA's manual is very flat and primitive...
never heard of term "logical operand".
i guess you mean "logical operator"...
there are only three basic ones so... there is not much to it.
and... they are not something specific to KRL, they are essentials that qualify as general computing concepts.
but that is just the basics. it explains what to expect when writing logical expressions.
logical expressions only evaluate some state(s) at bit level. we are talking about: AND, OR, EXOR, NOT
this is extremely useful and it is a key to any sort of programming but to truly unlock the program power is to apply same thing to groups of bits.
and not just to evaluate but to manipulate values.
this is where instructions B_NOT, B_AND, B_OR, B_EXOR come in.
so... what exactly trips you?
