3. The value range will now be 0.00 x 300....50.0 x 300 = 0...15000 A.
DNP analogue values deadband
The deadband is always defined in units of the original value when scaled using the
internal (fixed) scaling factor, irrespective of whether the internal scaling factor is
used for value presentation or not.
Example
For a deadband of 2% I
n
value is set as follows: 0.02 x 100 = 2. If the scaling factor is set to 300 A, the scaled
deadband is 300 A x 0.02 = 6 A.

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,
503...504, 507 and 601...603.
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 HMI 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
