Fanuc 0MC PMC programming, software ??

[Bruce Griffing]

I am interested in setting myself up to program the ladder in my Kitamura Fanuc 0MC control. I am looking for software, manuals, procedures etc to get started. I am hoping that I can download the present ladder from the machine and add some features like probing and another axis. I realize that these will also require hardware, but I would like to be able to do this myself. Suggestions? I understand that the software to do this runs on DOS - thought that may no longer be true. Any help would be appreciated.

You may already have a skip input, if so you hook this to a probe and use the G31.
No ladder change is required.
This is the normal I/O skip and is usually fast enough for most probe applications, High speed skip requires a hardware add on that bypasses the slower PMC skip input.

Al, thanks for the reply. I looked in the manual for my Kitamura Mycenter 1 - there is ladder logic there for a probe but it is marked optional. Three inputs are required for the Renishaw probe and setter shown. When I examine the ladder on the machine, these rungs don't exist. So my assumption was that it is a no go as is.

The maintenance manual also clearly shows the hardware necessary for another axis - but this is also not present in the ladder.

Many inputs are dedicate inputs such as X008.6 PMC skip input, If you can locate this on your I/O then you most likely can input a regular skip input into it.
I am not sure what the Renishaw needs three inputs for?
You can test this easily enough, if you write a simple program with a G31 in the block and trip the input with a manual switch and see if it drops through to the next line when tripped.

Al - Thanks for taking an interest. I do need help. Here is what I did - when I look up x008.6 in the ladder and find a blank rung I concluded that there is nothing to connect to - is that wrong? If so where would I connect something?

As to the three inputs, I am away from the shop for the rest of today and tomorrow, but I will post the page from the ladder tomorrow night so you can see them. From memory they were status related, but that could be wrong.

I am still looking for the PMC-K, -L, -M programming manual listed in the Series 0 C manuals.

Greg-
I did not know that they existed. I have had good luck ordering from Fanuc directly - prices on the high side of reasonable, but not out of sight. Have you tried to order from them? I'd guess $30-$45. I'll call myself next week.

"I am still looking for the PMC-K, -L, -M programming manual listed in the Series 0 C manuals."

there are loads of these books out the back of Fanuc UK, in a skip as they're moving offices.

If you'd of posted this a week or two ago i could of got them mate.

Bummer.

In regards to probing, there will be a dedicated X address for the input of the skip signal (X8.4 i think - check). Give the probe a 24vdc and 0vdc path, then wire the signal into X8.4 - jobs a good one...

The pmc software is Fladder 2 for your control.

Thanks for the input. I have another question - Is it possible to remove the EEPROMS from the OMC control and maintain the other memory on battery? Or are all of the parameters lost in the process?
Also - do you know what part number the EEPROM is? Thanks in advance

[gbowne1]

Yeah, I've tried to order lots of stuff from them. They wanted to know if I was a company and requested my information. For instance, I need a new keysheet for the 0M-C CRT/MDI for a mill. Mine has most of the key labels broken off. The right Part # is $90 on ebay.

Bruce,

Technically, you should be able to remove the board with the ladder proms without bothering the parameters, but I wouldn't advise it. It is so easy to just punch out the parameters and diagnostics, why not do it beforehand?

If you haven't done it already, you should do it soon. Remember to press EOB while pressing 'Output Start' so you get the 900 option parameters punched out. Punching from the Diagnostics screen gets you another file with N numbers in the 10000 range. The Diagnostics file contains the timers, counters, keep relays and other ladder related data.

Regarding modifying the ladder on a Zero, you'll need a Fanuc prom writer to burn your Fladder changes. Also, not all Fladder versions will work with every existing ladder. You need the version that is correct for your PMC.

Good luck,
