Problem with setting output, software related...

[team08]

I am having a problem setting the output in the following file:

'Put Tool in Holder #1
OPEN "C:\SbParts\TC\MONITOR.SBP" FOR OUTPUT AS #1
WRITE #1; "STATUS=BUSY"
CLOSE #1
VD,1,3,0,0,0,1,0,2.54,0,1,1,75,0,8800,4600,0
JS,8,4
MS,3,0.5
ST
SO,1,0
ST
J2,&PRESTAGE1X,&PRESTAGE1Y
JZ,&PUTOOLHEIGHT
PAUSE &DWELLPUTOOL
M2,&TOOL1X-&XADD,&TOOL1Y
SO,2,1
PAUSE .2
MZ,&ABOVEHEIGHT
SO,2,0
J2,&PRESTAGE1X,&PRESTAGE1Y
OPEN "C:\SbParts\TC\MONITOR.SBP" FOR OUTPUT AS #1
WRITE #1; "STATUS=DONE"
CLOSE #1
END

The line in particular is SO,2,1. If I type this command in the console manually, it turns on. I have tried messing with the pause time, and what comes before trying to turn on output 2, but no luck. I tried making this file:

SO,2,1
PAUSE 1
SO,2,0

and it works. I cannot seem to get the output to work in that file for the life of me! The machine pauses and then lifts in the Z axis and finishes the file, completely ignoring the part where it should set output 2. Any suggestions?

There must be some optimization going on in the SB3 parser. That one is particularly interesting as I have never had problems with the discrete outputs, then I never tried to "pulse" them which is what your app does. Discrete 1 turns on the router, I know #1 has "extra logic" associated with it outside the control of the sbp file, such as "wait for the start button". Does #2 have some hidden baggage also?

How about setting an unused discrete, say #5, at the beginning of the file and clearing it at the end? Does that work?

Is it a type O you have PAUSE .2 in your line above should it be PAUSE 2

I will have to try setting another output. Output 2 in my case is the output to the solenoid that controls the air supply going to the draw bar on the tool changer. It should be releasing the tool. Maybe I will give shopbot a call tomorrow and ask them about it.

I thought maybe it had a problem with the .2, and tried other values in there but no luck. I tried putting the command in twice, and still no luck. Thanks for the suggestions, keep em coming if you have any more!

Greg..
Have you checked the relay and connections? My TTL output relay boards have lights that signify when active. Activate output 2 manually and use a digital voltmeter to check that it is actually sending power to the switch.

Well I think I solved the problem. I put a pause in here:

M2,&TOOL1X-&XADD,&TOOL1Y
PAUSE1 <----(new pause)
SO,2,1
PAUSE .2

I think that maybe the power supply was dragged down just after the previous M2 command and could not turn on the solenoid? So the pause allows a little dwell time before powering the output. I have not looked at it on a scope but it sounds plausible.
