Values for error behaviour
0 = pre-operational (only if current state is operational)
1 = no change of state
2 = stopped
3 �� 127 = reserved

Error register (1001h)
The error register indicates the general error status of the device� Every bit stands
for an error group� If a bit is set (= 1), at least one error of this group is active at the
moment� The contents of this register are transmitted in every EMCY message�

Pre-defined error field (1003h)
Every inclination sensor keeps an error list of the last five errors occurred� The
entry 1003h/00h contains the number of error entries in the error field�
All other sub-indices contain all error states occurred in chronological order with
the error last occurred being always found under sub-index 01h�
The oldest error is in the highest available sub-index (value of 1003h/00h) and is
the first to be removed from the list in the case of more than five errors� If an error
occurs, a new error entry is added to 1003h and also communicated via an EMCY
message�
