10.2.3.3 Setting register
The release settings are arranged in three groups (groups 0 to 2).
Each group can be conceived as a binary array of information.
Before reading or writing the settings, the appropriate group should be
selected. Access to the groups are obtained via sub index 0 and index 2003
(hex), 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 sub
index 0 and index 2002 (hex), 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
