SOS button
This button has 2 different purposes, depending on
the moment when it is pressed: at system power-
up or when the system is already running.
POWER UP ACTION (the SOS Button is pressed
during power up)
This action is useful when the "out-of-factory" state
of the card needs to be exactly restored.
SOS button
The RestoreFactoryParamters (0x05) function is
automatically called, and the actual IP address is overwritten with the SOS IP
address written on the sticker of the card (169.254.5.1). After that, all these
parameters are automatically saved in the User's parameters memory with
the SaveUserParameters (0x03) function.
RUNNING ACTION (the SosButton is pressed while running)
This action is useful when the user has lost the actual IP address of the card,
and temporarily needs to connect to it without changing all of the card's
parameters.
Only the IP address is overwritten, using the SOS IP address that appears on
the card's sticker (169.254.5.1). This new IP will be valid only after all TCP/IP
connections (web pages included) have been closed.
In this case the SOS IP address is not automatically saved, so if you need it,
you will have to manually call the SaveUserParamters (0x03) function.
Otherwise, the previous IP will be reloaded upon the next power-up.
Warning:
Do not use the "SOS IP address" as the normal IP for your module (during
normal board operation). If you plug another module on the same network,
both will have the same IP and will therefore be impossible to both
configure.
