4.2.2 Maximum and minimum electrical parameters
Registers 96 to 191 store the maximum values of each parameter (see
column “Maximum” in Table 9). Registers 192 to 287 likewise store analog
the minimum values recorded (see column “Minimum” in Table 9).
4.2.3 Communication (RS485) setup
For the communication (RS485) registers 1000 to 1002 are used.
4.2.4 Password setup
The settings can be protected with a password in order to prevent data from
being (accidentally) deleted. The password will be required in order to make
any changes to the settings.
The registers 1050 and 1051 are used to set the password.
4.2.4.1 Password setting
In order to protect the settings, the password must be written at position
1050, followed by writing 0x0100 at position 1051.
4.2.4.2 Delete password
For un-protecting the registers, it is required to write, in the same command,
the password at position 1050, and a 0 at position 1051.
