Verify Door Overide in Program

[bjhall06]

Is there a way to add some sort of check in a production program which would verify that the Door override switch is turned off?


We have a HAAS VM-3.

Scratch that, I figured it out.

In case any one is interested:

If[#6051 EQ 1] GOTO A
GOTO B
NA #3000 = 15 (ALARM MESSAGE)
NB PROGRAM START

You cannot use letters with N addresses. Replace A with 1 and B with 2 and you should be ok.

I have seen other customers do the same thing, except they use a protected sub-program. If you write a sub-program and assign a program number in the 9000 series, you can hide/protect it with setting 23.

So, Ken

Would you use a custom M code to call a sub program (in the 9000's) and call that M code at the beginning of that program?

I'm just trying to figure out the application. I think this is kind of interesting. So, to keep the operator from doing something dangerous you could lock the keypad so they can't edit out the sub call...??? I've never messed with locking the keypad before. Is that password protected?

[KenFoulks]

There are no passwords that can be used, you can use setting 8 to lock the memory. The newer Haas machines come with physical locks that can be used to restrict access.


You can turn off settings 74 and 75 to help hide the door check.



Here is a sample program outline:

O00001 (Part Program)
M98 P9999 (Check Setting 51)
G00 G17 ......
(Part Program)
M30


O09999 (Setting 51 Check)
G103 P1 (Limit Block Look Ahead)
If[#6051 EQ 1] GOTO2 (Logic)
G103 (Unlimit Block Look Ahead)
M99
N2 G103 (Unlimit Block Look Ahead)
#3000= 1 (Turn Off Setting 51)
M30

Yea, sorry I should have been more specific. I will probably set this up as a subprogram also.

Thanks!

It is those reasons that I figure it is a bit of a waste of time, Ken. If they are crafty enough to want to turn off the door override when running production, they are probably crafty enough to figure out the other settings...

These controls could use a keyed lockout like most other controls have as well as an actual lock on the door.

These controls could use a keyed lockout like most other controls have as well as an actual lock on the door.

The new Haas machines come with both. Call your local HFO and ask them if you can get a memory lock keyswitch installed. It locks the programs and settings.

Thanks Ken. I may check that out. Thankfully for me I am at a a place where there are no other machinists to mess with my "toy".
