Permitted value ranges Transferred parameters and values are checked by the
MTR-DCI before being accepted.
Note
In the case of invalid parameters or values, an error mess-
age will not appear in the response; rather, the received
value will always be returned.
– Invalid parameters will not be accepted.
– Values outside the permitted value range will be limited
to the nearest valid value.
Recommendation:
Check that values and parameters have been written correctly
by downloading the current contents of the parameter or
value with one of the following Read commands:
Error messages If errors are made in commands (syntax faults), the value
<0xFF> will be transmitted instead of the usual response.
Possible causes:
– Incorrect initial character, separating character or empty
character
– Incorrect hex digit
– Incorrect value type
