SPA bus communication protocol parameters

Altering parameter values via serial communication requires the use of the SPA
password in some cases. The password is a user-defined number within the range
1...999, the default value being 1. SPA parameters are found on channels 0...5, 504
and 507.
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
