1 = included in the event reporting
Events E50 and E51 are always included in the event reporting.
4.1.9.4. SPA bus communication protocol parameters
In some cases, altering parameter values via serial communication requires the use
of the SPA password. The password is a number within the range 1...999, the default
value being 1.
To enter the setting mode, enter the password into parameter V160. To quit the
setting mode, enter the same password into parameter V161. The password
protection is also reactivated in case of loss of auxiliary voltage.
The HMI password can be changed via parameter V162, but it is not possible to read
the password via this parameter.
Abbreviations used in the following tables:
• R = readable data
• W = writeable data
• P = password protected writeable data
• I = input data
