Communication commands according to EN 62056-21
Page 50 of 62 ZDUE-LTE-PLUS-VII
9.2 Set password
For the execution of various commands, the transfer of a setting password
(as a 2nd data set) is required. Depending on the parameterisation, the
following cases can occur during communication between the ZDUE-LTE-
PLUS-VII and the head end system:

No setting password parameterised in the ZDUE-LTE-PLUS-VII
(string length = 0):
In this case, the ZDUE-LTE-PLUS-VII will not evaluate the transmitted
setting passwords (all password-protected commands can be
executed!).
The request to send the password (P0-Operand) when activating the
programming mode may in this case be answered with the password
command (P1 command, password arbitrary). Alternatively, the head
end system can continue the communication by sending another
permissible VDEW command.

Set password parameterised in the ZDUE-LTE-PLUS-VII
(default: '00000000').
All passwords sent by the head end system must match the
parameterised one, otherwise the communication will be interrupted
by a break command from the ZDUE-LTE-PLUS-VII. The request to
send the password (P0 operand) when activating the programming
mode must be answered with the password command (P1 command).
The immediate sending of another VDEW command is not permitted.
9.3 Parameterisation commands
The parameters are set and read via W1 / R3 commands (ASCII coded
characters).
The individual parameter segments are selected by the class; in principle,
the command parameters 'Offset' and 'Length' can be used to access
individual parameters or parameter ranges in a class. However, this is not
supported by the ZDUE-LTE-PLUS-VII the classes can only be written or
read completely ('Offset' and 'Length' of the class equal '0000').
