8.3.2. Set command
The setter command can be used to modify the value of a property.
Command format: SET[nodePath].[propertyName]=[newPropertyValue]
Response format:
The response for setting a property to a new value is the same as the response for the
‘GET’ command. The value in the response is the new value if the execution of the ‘SET’
command was successful, otherwise the unmodified ‘old value’ with an error message.
pw[nodePath].[propertyName]=[newPropertyValue]
Example:
> SET/SYS/MB/RS232/LOCAL.Rs232Mode=1
< pw/SYS/MB/RS232/LOCAL.Rs232Mode=1
Error response format:
If there were errors during setting a property, an error message follows the unmodified
property value.
pE[nodePath].[propertyName]=[umodifiedValue] %EXXX:Error message
Legend:
XXX: error number.
Examples:
> SET/SYS/MB/RS232/LOCAL.Rs232Mode=11
< pE/SYS/MB/RS232/LOCAL.Rs232Mode %E005:Invalid value
> SET/SYS/MB/RS232/Local.ActiveProtocol=LW3
< pE%E004:Writing read-only property
8.3.3. Invocation
A method can be invoked with the help of the ‘CALL’ command.
Command format: CALL[nodePath]:[methodName]([parameter])
Response format:
The response for a method execution is a state and a value. The state is mandatory and
always defined if the method could be executed. It can be either a success or a failure. The
value is optional and it can contain additional information, such as the reason why the state
is a failure or a specific value when the state is success that the client can process. It is
also possible to get an error message when the method could not be executed – e.g. the
parameter was illegal - and hence not even the state of the execution could be specified.
mX[nodePath]:[methodName]=Y
Legend: X can be:
‘O’: if the execution is successful.
‘F’: if the execution is failed, but the method could be executed.
‘E’: if the method could not be executed: e.g. illegal parameter count.
Y can be:
 The return value of the method if any.
 It is valid that a method does not have any return value. In this case,
the equal sign (‘=‘) can be omitted.
Example:
> CALL/EDID:switch(F46:E1)
< mO/EDID:switch
