13.3 Communication syntax (serial and Ethernet)
The serial interface is used for communication with the device (EWR 2 or EWR 2 Net). The Ethernet interface is used for
communication with the device (EWR 2 Net). The same data is transferred via both interfaces. If a data set is requested via
an interface, the device sends the reply back via both interfaces. That is why only one interface may be used, otherwise it is
not possible to uniquely assign a reply to a request.
The device is initially passive upon start; communication is started externally in the form of commands. Each command has
a certain number of arguments and the final [CRLF].
Function/explanation
Commands and argument(s)
Separated by spaces. A reply is sent for each command. The reply consists in turn of the same command and a specific
number of arguments and the [CRLF]. There are also commands that produce a multi-row reply.
Error "err1" / "err2" / "err3"
If the error is unknown or if the authorization is not sufficient, the error message "err1" is issued. If the command exists, the
authorization exists, but the number of arguments is wrong, the error message "err2" is issued. If the command exists, the
authorization exists, the number of arguments is correct, but the values of the arguments lie outside the permissible limits,
the error message "err3" is issued.
Active commands
All active commands in the current authorization with a short description are issued with the command "???". The reply has
multiple rows.
Command "pw [Password]"
The authorization level can be changed with the command "pw [Password]". The authorization level can be queried with
the command "pw" (without argument). "Access level [0–3]" is sent as the reply. The password can be read and changed
at the Setter authorization level. (Command "cspw xxxx").
