OSP5020L serial communications

[JonLed]

Ok, I've been through every thread in this 'Okuma' forum. I've got several documents on setting up the serial port, but no success yet.

Basically, everything I've tried returns a:
2129 RS232C ready status time out ERROR FFFFFFFF 'write'
error.

Seems to me this would be caused by the control not seeing the DSR (data set ready) signal, but the cable is connected at pins 20 and 6 and there is about 12 volts on both of these lines.

Any suggestions?

Thanks,
Jon

Is transfer initiated by "PIP" or "DNC" ?

Can you "WRITE" as well as "READ" ?

Are your transfer settings at the PC and machine correct ?

PIP method
Some say a "%" is required on the first line
If the file name pre-set for the machine is set , it must be before the % sign and after a "$" sign
e.g First line to be read by the machine is the file naming line $1234.MIN%
if this is not present, and a % present, the file will be named A.MIN by the machine

note! there is a procedure to go through to read or write a file depending upon the machines default ports this can also address the renaming of that file.

and

All methods
Most Okumas require "%" at the bottom as this terminates the reading function at the machine.
If this is not present, this can cause the time-out error you have recieved
and can freeze the screen ( reboot required )

Superman,

I'm using the PIP method, and I've not been successful either direction, though mostly I'm trying to send to the PC from the control. I've tried a hardware hand shaking cable and software hand shaking cable, with corresponding settings at the PC as well as the control.

No luck yet.

Thanks,
Jon

first thing to look at is your communication settings on the machine and PC
make sure that buad rate , stop bits, etc. are the same

next , check what your default devices are eg. "read" device = paper tape and "write" device = printer (TT)

CN0: is the RS232 port

to bypass the machine defaults try <pip> <punch> CN0:<filename1.min> <write>

next try sending a test program from the machine to the PC as this ia a bit more forgving, as the machine adds its own start and end codes to the program where necessary.

read your manual on how to rename a file when reading or punching ( it may help in the future )

Unfortunately we didn't get any manuals with the machine, the local distributor has emailed me some things, but none of which cover control operation. Their technician is emailing me a guide for what they use, but it sounds like a re-hash of what I already have. I've checked all the parameters and terminal setting, they look good.

From what I've read, it seems like the control is not seeing a signal that it wants in order to start transmitting.

<pip> <punch> CN0:<filename1.min> <write>
Gives a 2105 device name ERROR 'CN0'

Any idea what protocol to use for file transfer in Hyperterminal?

Jon

[Superman]

Give me a little time , I'll try to get some more info on the cable ( pin config ) and transfer settings from our setup ( I hope )

Anybody esle care to jump in the meantime.

[JonLed]

Brought my RS232 Break-out-box in today. Seems that the jumper between pins 4 and 5 on the control side is causing the problem. After removing that, I communicated both ways. Need to play with it some more to make sure everything is good to go.

Apparently I wasn't successful in sending from PC to control. I keep getting a 2510 input filename not the same ERROR.

I've made sure the program starts like
$FILENAME.MIN%
...
...
M2
%

And I've tried changing the parameter bit for read filename with no difference.

Still plugging away... half way there.

Jon

[Superman]

Great, we are nearly there
That alarm tells us that the "NAME_OF_PC_FILENAME.MIN" and the '$FILENAME.MIN%" are different

see this thread about the renaming of the incoming file
http://www.cnczone.com/forums/showthread.php?t=68676

<PIP> <READ> [CN0:<original_name.min>,<new_filename.min>] <WRITE>
note the comma, the tells the control to rename the incoming file from Original_.Name to new_filename.min

so if you
<PIP> <READ> [,B.MIN] <WRITE> the file in the control will read in as B.MIN

and simpler still
<PIP> <READ> [,] <WRITE> the file in the control will read in as A.MIN, which is the default name

as a note , anything that is set as default, does not need to be stated.
if your RS232 port is set as default for Reading and Punching then CN0: is not necessary same goes for .MIN

You should be now doing cartwheels

[JonLed]

I tried that and now it gives:
2504 no tape data ERROR

It will be probably Tuesday before I can mess with it some more... had to pull the spindle motor to replace the cooling fan bearings.

Jon

PS. Cartwheels are out anyway... bad back

[Superman]

Probably jumped the gun,
It seems to need a device in the command line ( CN0: etc ) as is seems to be tryig to use a paper tape reader
Do you know how to check to see what is the default READ device and default PUNCH device ?

Yes, they can be different and create big problems trying to sort these comms out without knowing what they are
Could you alter it if given clear instructions ?

Do you get the same error sending the file the reverse direction ?
Type the command and the error for both ways for us

What lathe machine for the OSP5020L, we have LB15, LB25 ?
( dosen't mean much as the parameters should be the same that control the comms anyway but it's good to know for when I go looking for the manuals )

Please amend this to your wiring and I'll compare to ours and the manual
BTW this not our setup

25 Pin connections on cables ( XXXX = no wire )

Spindle motor cooling fan blowing away...

According to 3 different setup documents I have, the punch port and read port are set with NC optional parameter words 44 and 54 respectively. Punch port is set to 0 and read port is set to 1.

I'm not getting any errors when sending from the control to the PC, that's working fine. Just having problems now sending from PC to the control, even when specifying a read device on the command line.

The lathe is an LB15.

My current wiring is this
