Hy, can i use "and" , "or" operators ?
someone has a full list of operators of "IF" function ?
also, a list of available comands, as "IF", "While" ?

kindly ! za kitten )

Here is document

AND format example:

IF [[[V181 EQ 1] AND [PP EQ 2]] EQ 1]NHOME

OR could be used in place of AND in this example.

hello again, please i don't understand something in your example :

IF [[[V181 EQ 1] AND [PP EQ 2]] EQ 1]NHOME
IF [[[true] AND [false]] EQ 1]NHOME // supose conditions are true and false
IF [[false] EQ 1]NHOME // how does this work ? [false eq 1] ?
and what means NHOME ?

kindly !

hello again, please i don't understand something in your example :

IF [[[V181 EQ 1] AND [PP EQ 2]] EQ 1]NHOME This one = if true and true, goto line NHOME
IF [[[true] AND [false]] EQ 1]NHOME // supose conditions are true and false Since this is an AND statement, both need to be true or EQ 1 in order to jump to line NHOME. if it were an OR statement, only one of them would need to be true in order to goto NHOME
IF [[false] EQ 1]NHOME // how does this work ? [false eq 1] ? IF the statement is false, it does not goto NHOME, but goes to the next line in the program following the IF statement.
and what means NHOME ? Just a line name vs a line number to jump to. Nice to use names since they mean more and using the sequence renumber sill not change them if used.

kindly !

hello mr. Wizard nice to hear from you again

i am missing something :

v1=1
IF [[v1 eq 2] eq 1] = IF [ false eq 1] // i dont undersand how can "false" be compared with "1" ?
This comparation is between a boolean (or logical) expresion with a numeric expresion.
IF [ false eq 1] GOTO N100 >>> false=1 and will go to N100, or false<>1, and will skip to next line ?

or is it "false=0" and "true=1" ?

and another thing, about NHOME ... until now i used only numerical adreses, N100, etc, but NHOME is more human ... please, is there a condition for this adresses, like Nxxx, all begin with N, and word should be 7caracters long, and xxxx can be letter or number ? something like that ? ...

For example, i would like to code like this :

drill14 call OS01
drill6 call OS02
reamer call OS03

but i think i can not, so can i use this :

Ndrill14 call OS01
Ndrill6 call OS02
Nreamer call OS03 ?

This is taken from a programming manual,
format is Nxxxxx ......x can be any number or letter only, maximum of 5 characters after the N

some programmers use NA1 or NB1
where this "label" style may be used to indicate an A or B turret restart line on a lathe

Sequence Name
All blocks in a program are assigned a sequence name that begins with address character “N”
followed by an alphanumeric sequence.
Functions such as a sequence search function, a sequence stop function and a branching function
can be used for blocks assigned a sequence name.
A sequence name that contains only alphabetic characters is called a sequence label and the one
that contains only numbers is called a sequence number. In this manual, both of them are referred
to as a sequence name.
Sequence Name Designation
• Enter letters of the alphabet (A to Z) or numbers (0 to 9) following address character “N”.
• Up to five characters can be entered in succession to the address.
• Both alphabetic characters and numbers may be used in a sequence name. If an alphabetic
character is used in a sequence name, however, the sequence name must begin with an
alphabetic character.
• Although a sequence name must be specified at the beginning of a block, an optional block skip
code may be placed before a sequence name.
• Sequence numbers may be specified in any order.
• Since sequence names are handled in units of characters, the following names are judged to be
different sequence names.
• N0123 and N123
• N00 and N0
• When a sequence label is used, place a space or a tab after the sequence label

Superman is spot on with the rules. Where you are having trouble or not understanding is how the AND statement is being used. If you look at the example:

IF [[[V181 EQ 1] AND [PP EQ 2]] EQ 1]NHOME
IF TRUE AND TRUE EQ TRUE NHOME

A normal IF statement would be:
IF [V1 EQ 1]NJMP1
IF TRUE NJMP1

If either example is FALSE then the next line will be executed in stead of the jump.

Hope this helps to clarify.

so, If [ false eq 0] = IF true ?

[OkumaWiz]

Yes,

But I'm not sure you are getting it yet. Because we are checking a variable we can either check to see of the variable is true or false depending on what we are checking.

IF [V1 EQ 1]NJMP1 = IF variable #1 is = 1 goto line NJMP1, if it is not = 1 goto the next line
IF [V1 EQ 0]NJMP2 = IF variable #1 is = 0 goto line NJMP2, if it is not = 0 goto the next line
IF [V1 EQ 128]NJMP3 = IF variable #1 is = 128 goto line NJMP3 if it is not = 128 goto the next line

Now we can change the logic by changing the criteria;

NE = NOT EQUAL
LE = LESS THAN OR EQUAL
LT = LESS THAN
GT = GREATER THAN
GE = GREATER THAN OR EQUAL


Just about anything you want to accomplish can be done using these logical codes. Perhaps you should tell us what you are trying to do rather than get caught up in boolean logic. We may be able to better help you.

For example, here is a panel switch check routine that is commonly used on a twin turret, twin spindle LT200MY. It is used to verify that the operation panel switched are correct for normal operation of the machine. We can check to make sure coolant is ON, Feed rate override is at 100%, and more as shown. We can even generate our own alarm messages:

G13 (WRITTEN FOR LT200MY WITH P200 CONTROL)
G140
(TURN FEED TO 0 AND SINGLE BLOCK ON FOR RESTART.)
( SWITCHES CAN BE ADJUSTED AFTER CHECK HAS OCCURED.
INDIVIDUAL MODE CAN ONLY BE USED DURING RESTART.)

As you can see, the sky's the limit on what you can do, but don't let it intimidate you. Most of it is just basic yes/no logic.
