The release settings are arranged in three groups (groups 0 to 2).
Before reading or writing the settings, the appropriate group should be
selected. Access to the groups are obtained via API 0 and index 3, which is a
R/W register used to select the respective group (default: group 0).
The high byte contains the desired group number, while the low byte must
contain the value 255 (0x0FF).
Prior to writing the settings, the correct password must be entered via API 0
and index 2, and the settings have to be written within 10 seconds of the
password check.
For trip units that support settings, the settings of groups 0, 1 and 2 should
be written one after the other.
The setting groups are assigned as follows:
•
Group 0: System group
•
Group 1: Protective group
•
Group 2: Modbus group
