Hello, I'm working with a Sinumerik 840D sl. And we are facing a problem regarding to some tool data that is tryed to be acquire from NC to PLC DB. On FB2 we are getting Status 401 but I havent found information about that block. The block help is in German and doesnt have the status codes meanings.

Does anyone knows something about this. Many thanks.

Regards.

Hello again.

I found the manual, it says that there are 4 variables with access error.

I'll try to solve this and let you know the results.

Regards.

Hello fghlw.

We noticed that in the program a non declared TUD variable was trying to be read.

We noticed that OEM had just declared 8 TUD data. So we just used variables number 7 and 8, because they were spares, instead of numbers 9 and 10.

New question published by carlosdody is split to a separate thread with the subject Manual of FB2 errors .

Best regards
