This is a configuration issue. While we implemented the connection to Bühler machines according to the companies specification, it seems that there are some machines (maybe running older firmware versions!?) that do not support the retrieval of the machines state as documented.

The fix is easy. Just deactivate that S7 channel by setting the Area of input 6 to the empty entry such that this data is no longer requested from the machine.

You should also remove those two alarm rules are that refer to this machine state

We will add a machine setup RM 20 Simatic Legacy which will provide those changes with the next Artisan version.
