Fanuc 0-TD / 0-T No program in library. Can't enter a new one.

Well, either we are talking aboot 2 different switches here, or you are FOS. ;)

I jist went to start a new program*, and I got this.

My Fanuc 0MB just ignores what you key in. Oh well that’s what I get for making broad statements 😳.
 
I think it is possible that different builds may respond differently, one builder may have implemented an alarm in the ladder, the other maybe not, given the G122.3 diagnostic bit on mine is at 0 (harware data protect key) [i can post the maintenance manual if needed and allowed] should result in an alarm when i try to write a new program. Yet it doesn't, not sure but maybe it is also older, monochrome crt instead of colour (that is just my theory, i am new to fanucs after all).
Btw the memory must have been wiped either by the tech or the previous owner, there are not programs in the library.

0MC here, I nearly took the keypad out because it wasn't letting me insert or hit EOB. After 5 minutes, realized the key was set to protect. No alarms here, either.

Most 0 controls don't have color (0D might all have it?) so even if it told me write protect on the screen (which it didn't when simply typing a line of code), it wouldn't have been obvious.

I think it might tell you write protect if you tried to insert a program number. Or might might tell me if I did the same. But that's not what I was doing.
 
OK, I think the model is the issue here.
My post above was for an 18, but I went to the 0 that I am at odds with (monochrome as well) and there is no PROTECT key on that (that I have found) and as long as I am in EDIT, it let's me doo anything that I want.

I am sure that all of my 18's react the same, as well as the 16 that we have that is a retrofit.
(NOT a Hardinge.)

AFAIK, there is no ability for a builder to create an alarm if an attempt is made to enter data with the memory protected. I don’t recall there being an F address that the builder could read in their ladder that indicates data is attempting to be written.

Were you able to find the X address for the physical switch and verify it is changing state when the switch is operated?

I found the address in this manual, it is from GE, my machine is not GE but it is the best i have found for Fanuc 0-series machines. Though the physical switch G122.3 is not changing on my machine, maybe it doesn't even have one or maybe i can't see 10cm in front of me. But the software operation panel switch does change F178.5

Mr. 86 is burnin' the midnight oil!

Without looking at a map / just guessing - you must be on GMT+1?
Maybe GMT+0?


That file is "GE Fanuc"
GE merged (?) with Fanuc controls back in the early 80's?

G122.3 is not the physical switch. It is an output from the PMC to the CNC. All physical inputs to the PMC will be X addresses. You will need to look at a wiring diagram from the machine builder or their ladder program documentation to figure out which X address they used.

The memory protection input to the PMC (X whatever) is processed by the builders ladder logic and then output to the CNC in the G address. Even though it really doesn’t need any processing, the option exists for a builder if desired. This is where a builder could implement use of a physical switch as well as the software switch. The logic could be written as an OR condition. The X address OR F178.5 turns on G122.3

Is it too much to ask for a picture of the control panel?

My phone for some reason can't focus and takes a blury images like it is a 2.0MP from the early 2000s, so i found one that is exactly like it from the same model.

Is there a key hidden underneath that RS232 cover plate on the left side of the CRT?

If there is no edit lock key, then perhaps the I-O input parameter is set incorrectly and that is causing you this problem. Just guessing at this point.

No key near the rs232 port or under its cover.
That is what i am guessing, the tech must have passed parameters from a machine with a key or it could even be from a mill for all i know.

If your machine has the 0TD the same as the pictured machine, you can view the ladder on screen. Search the G122.3 output and post a pic of the logic that actuates it.

Verification of the edit lock function is super simple yet we have spent 3 days posting things to check yet have not made progress. 😵‍💫

Either i am that dumb (entirely possible) or it can't display the ladder logic.
I tried from the start to enter the ladder screen (i know ladder from PLCs very well so i knew this would help me solve the mystery) but i haven't figured out how, and i think i read something that some controls can't display their ladder diagram.
What is the normal procedure to display the ladder? As far as i know, i just have to press the DGNOS/PARAM key several times until the ladder is shown. Maybe there is a requirement for that to work that i missed.
 
That's how I stumbled onto the ladder on my 0TD today.
Just the param key a few times pulled it up.
I wasn't looking for it, and would have expected to have a soft key label to direct me there, but apparently not....

That's how I stumbled upon the library in my 0TA.
But they were random keystrokes that dropped me in there, and I had to try to remember what I pushed to git me there.
What a friggen nightmare....

Set parameter 60.2 to 1 to enable ladder display. This only works on 0C and later.
 
I had an impossible time trying to figure out a problem on my C, had a tech helping and of course wanted to look at the ladder which I couldn't. He hadn't ran into a machine with it turned off before. It took more effort than it should have to figure out the param to display it, then a day later someone posts it on here...
