Modbus / Re: WJ200 low and high range hex frequency data

« on: January 25, 2012, 03:39:35 PM »

From what I have read so far I use a com port from computer but what about the plug
on the WJ200.  Do you know were I can find a pin out of the cable or instructions on what
I need to make?

You need an RS232 to RS485 converter if using com port.  You can also USB to RS485 converter.  A cheap converter from ebay didn't work for me with WJ200 I had to go with a B&B converter  http://www.bb-elec.com/product11.asp?sku=485ldrc9

Someone asked me to post the actual brain that I'm using.  Here it is.  I should post the MODBus set up screen as well.

I did make it work after getting help on yahoo group.  There are discrepancies in the Hitachi manual as far as modbus goes.  I'll have to double check, but I think the attached file is my latest brains to make WJ200 work.  I need to grab the actual brains from the machine.  There are curve correction multipliers to make the RPM read correctly for my mill.

CVI MachStdMill (MSM) / Re: Fly out panel and screen resolution

« on: July 08, 2011, 05:22:00 PM »

Dave, the main reason for me is to be able to change the FRO or Speed-overwrite quickly with a mouse click without opening the fly out window.

Couple of little comments I have about MSM.
I usually set WCO with probe before I load the file or do anyhing else really.  When you go to WCO / probing, there isn't a place to change the tool to the number that probe is assigned to, I have to go to a touchoff tab to change the tool number.  It would be more convenient to have the tool number change on the probing page as well.
The other thing is the tooling numbers.  I set tools manually on the machine for each job.  It would be nice if there were - + buttons next to the current tool field so that you can just click the buttons to increase/decrease tool number (like there is for tool viewer)
Lastly, sometimes I get lost and need to ref an axis or all axis when setting up tools, it would be nice to have a button on the tooling page at least for z axis ref.

Please excuse me if I missed something.

CVI MachStdMill (MSM) / Fly out panel and screen resolution

« on: July 08, 2011, 03:11:01 PM »

Hello Dave, I am running the trial version of the MSM with intent to purchase a pro license.  Wanted to test it out before committing.  So far I'm very impressed with the probing section.  The probing caused a lot of grief with other screens.
One issue I ran into is the fly out panel with 10x7 screen.  I have a 17" monitor with 1440x900 resolution so I have plenty of space horizontally.  I can stretch the window horizontally to be able to see full window and the fly out panel at the same time but when switching between the windows the fly out panel disappears.  I would like to use 12x9 screen set but I can only see the top of the window buttons if I pull up the whole window as much as possible (unable to switch between windows)  I guess I'm 50 pixels too short  .
So the question: is there a way to prevent fly out panel from disappearing?

I have few other comments but I'll try to post about those later.

Thank you

Modbus / Re: WJ200 low and high range hex frequency data

Made some progress on the coil writing issue.

From modbus test window if I write to coil 0 this value "FF00" the spindle turns ON and if I write "0" or "0000" the spindle turns OFF.
What I found is that the manual for X200 drive seems to be wrong bacause for X200 I could write "1" and "0" to turn ON and OFF.  The modbus section of both manuals is pretty much the same in fact WJ200 manual has X200 references which shows that the section was copied and edited but not carefully checked.

Anyway, now the question is how do I write FF00 to coil1?
I used the serial port monitor to see what message is going out to the drive when I turn ON the spindle from test window.  That message is:
01 05 00 00 FF 00 8C 3A
and to turn OFF:
01 05 00 00 00 00 CD CA

So from test window function 05 is used to write to the coil.
When I setup modbus and brain to write to the same coil, function 0F is used. This function writes data in consecutive coils vs. 05 which writes data in a single coil.  This might be O.K. but I can't make the value to come up as FF00.  It looks that there is a binary to HEX conversion when writing to modbus, so I tried writing 255 which equals FF in HEX but no luck, I think the message comes out with a value 00 02

An interesting observation is after I write FF00 to turn ON spindle and then read the current value back I actually get 0001

Spoke with Hitachi and was sent the attached document, after reading it everything still seems fine.

The example 3 in the document describes exactly what I am trying to do.

I also downloaded the ProDriveNext drive programing software from Hitachi and will play with that to see if anything jumps at me.

I did some more testing and still can't find the problem.  Using the serial monitor program I recorded what was sent to the drive.

Writing 0 to coil 0001:   01 05 00 01 00 00 9C 0A  I get no error
Writing 1 to coil 0001:   01 05 00 01 00 01 5D CA I get "unknown error" message and the coil doesn't change

The format looks fine to me.  I'm about to call Hitachi to see if I can get some support.

Now I'm really confused  .  I verified that I can read and write holding register for the frequency just fine either from modbus test window or using brain that I posted previously.

The problem is with coils.  I can read coils and receive 0 or 0000 I can also write back 0 or 0000 but I get an error when I try to write 1 or 0001.

I have checked and rechecked and rechecked again all the settings associated with modbus everything seems proper.

I tried everything I could think of at this point, all that's left is to beg for help.
