FANUC MDI mode not working (O-MD control)

[AymenTajine]

Hello everyone,

We have a 1000 YANG with an O-MD Fanuc control, few months ago we lost all the parameters, so we had to upload them manually and get it to work again, and since then we kept solving all the issues we were having,

For example few days ago we couldn't even upload a program, but now we're facing another issue,

When we try to input anything with the MDI mode, nothing is happening, we can't edit a program or even test the machine or put the tool offsets,

Normally the display "program(MDI)" should be showing the name of the program "address" and ends with "%"(1st picture) , but it's not even showing any of that (2nd picture),

is there a specific parameter I can modify please ?

When the parameters were lost, did you check the battery's?

The parameters were deleted, they weren't lost because of the batteries

Did you put in the Diagnostic parameters too? Double check every parameter as it only takes one bit to have been missed to hose you over.

Yes I did , but some of them are just impossible to modify , when I try to put them , nothing seems to change ( just a few of them ) the ones from 300 to 600 right ? ( DIAGN)

That because the ladder is writing to them. That should be OK.

So how am I supposed to put them when I can't modify them ?
