Dear all,

I bought a broken Hyundai HIT 8S with a `broken HDD` no backup only the green folder with machine parameters. Thanks to this forum I got it to work! (nulizhang fixed a machine without knowing it, cheers!)

The only thing left is the tool eye operation. the control expects that the probe is normally open but is actually normally closed. It is probably solved by `flipping a bit` somewhere in the machine parameters (I suspect somewhere in the NC parameters) 

The LED on the probe doesn't light but it has no effect on its operation as far as I can tell.

Can someone lead me in the right direction for solving this issue?

- Hyundai HIT 8S

- Sinumerik 840C

- Simodrive 611 Analog

- MMC V04.09.54  V05.05

- MARS I/SW 2.1

I am only  able to upload 1 Picture but I have more if necessary.

Kind regards,

Bas.
