Encode the status_type byte as follows:
Status type: 48 (manufacturer-specific)
‘Status’ specification: 1 constant
Encode the slot_number byte as follows:
Slot number: 0 (because only slot 0 is being used)
Encode the specifier byte as follows:

59 bytes subsequently remain freely available (user_data):
Errors are indicated using the user_data fields.
The user_data fields are each combined in blocks of 3 bytes and
are interpreted as follows:
1 - Services
2 - Error type
3 - Type of data access (read/write)
Up to 19 errors can thereby be indicated.
