Status registers of all subscriptions
From MR 250000, you can read the collective status of all subscriptions. In
case of an error, you first read out the ID of the subscription, in which an error
has occurred.
Meaning of the individual bits
Bit 0 Error in CRC computing of the configuration file
0 = No error has occurred.
1 = For CRC computing, the configuration file does not exist. For this
reason, CRC computing has not taken place.

1 = An error has occurred in a subscription.
At the moment, this is only a timeout error.
