5.1.15. 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 001. SPA parameters are found on channels 0...5,
504 and 507.
To enter the setting mode, enter the password into parameter V160. To exit the
setting mode, enter the same password into parameter V161. The password
protection is also reactivated in case of loss of auxiliary voltage.
The password can be changed with 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
