Macro Er.

[Bluesman]

OK why is this generating a MACRO format alarm?

#954=[#952EQ#1002]OR[#953EQ#1003]

Can I not use the AND OR XOR Bitwise operators on a Fanuc 16I
Just when I thought I knew everything too.
I have other ways to do this same comparison but was hoping to take care of it all in one line

Bluesman:

The statement to the right of your equal sign would result in a "true" or "false", not an integer. It's not possible to assign a true/false result to variable #954.

I'm not sure what you're trying to do here, but when you use that "EQ" operator, the result is always true/false, so the OR operator of two true/false results will also be true/false

You can use a statement like: IF[#952EQ#1002]GOTOxxx (true/false result)
Or you can say: [#952+#1002]OR[#953+#1003] (boolean OR of two integers)

Hope this helps

I was trying to send a value of 1 to #954 if either of the 2 statements were true. I need to make sure that if a cycle interuption happends before pallet exchange and after my broken tool logic traps the cycle. At a restart when it goes into a program loop it checks to see of the pallet it alarmed out on is till in the machine. If it is I need to complete the index before finishing the trap.
So I take #1002 or #1003 and transfer the value to #952 or #953 respectivly
If at a restart both #952 and #1002 have a value of 1 then I know the pallet never indexed out and so I GOTO and M60 then continue on with my containment part of the prigram.
But I just changed it with IF[[#952+#1002]EQ2]GOTO11 and that is doing the same thing I was just trying to figure out a simple way of doing it all in one statement.
I need to brush up on my MACRO B skills. I am going to FANUC in 2 weeks for soem much needed learnin

Thanks for your help, BLUESMAN

I am under the impression that,in fanuc, bitwise operation is possible only on arithmatic values, not on boolean values.
The result of [#952EQ#1002] and the other expression is TRUE or FALSE, which is considered a boolean value by Fanuc, even though the value is 0 or 1 (which can be used in some other expression, as arithmetic values).
