Hello Bruno,
What a wonderful error message : 'Error by tolerance evaluation'. I'm not quite sure that you've written down the correct error message.
If you want to know where the error comes from, you should ring the QUINDOS hotline. It's a standard rate number, and is manned by factory applications engineers.
I know the guy who wrote the QUINDOS DMIS interpreter, so if they can't help you, he certainly can.
On a more general note, if the error message appears in German it probably means that no one in the field has actually seen this error before, otherwise an English error message would have been written.
QUINDOS HOTLINE : Germany 6441 2109 222
Ciao !
