Okuma 2236 Alarm-B

[Mick]

I'm running a program (large) through DNC/DT on a Multus B400W/P200 control.

 

Using the DNC function, and the program has run fine until towards the end, and then I get the alarm:

 

2236 ALARM-B Program End Code Not Found

 

I've run it with a % at the end (normal programs are run this way) and without it, and I still get the error. Has anyone ever encountered this?

If your code ends with an M30 it'll throw an alarm.  Change it to an M00 and it'll fix the issue.  It can't "Stop/Rewind" in DNC, it can only "Stop".  :-)

We use M02 at the end of our programs (although we don't use DNC to run the program.) If you put an M331 before the program end code, that will stop the buffer from reading beyond that block, so it won't alarm out until the code actually gets read.

Thanks for the tips. I'll give them a try

I did do some tests, I cut the programme down to a real short length (about 15k) and ran it, and it ran through fine. A larger programme (about 1.3mb) didn't, and it alarmed up.

 

I tried it with M2 and M30, and neither worked. Running it off the hard disk also produced the same error. We had the local Okuma tech down having a look, and he couldn't solve it either.

 

I'll try the M331 code, and if that doesn't work, I'll try the M0 code

 

Again, thanks for the responses.

Do you have the DNC-DT option? If yes, is it turned on with DNC buffer and the DNC communication soft keys?

Sure is Greg

 

It was working fine, DNC'ing a 24mb file, but the error showed up when it was almost done. Ian stopped in yesterday and we tried a number of things, but nothing resolved it. It appears to be a buffer issue, as the same programme, shortened right down works fine.
