SOS button
This button has 2 different actions depending on the
moment when it will be pressed: at system power-up or
when the system is already running.
POWER UP ACTION
(the SosButton is pressed during power up)
This action is useful when the card needs to be restored
exactly back to the “out-of-factory” state.
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
SaveUserParameters
(0x03)
function.
SOS button
RUNNING ACTION
(the SosButton is pressed during 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 the parameters of the card.
Only the IP address is overwritten with the SOS IP
address written on the sticker on the card (169.254.5.1).
This new IP will be valid only after that all TCP/IP
connections (web pages too) will have been closed.
In this case this SOS IP address is not automatically saved,
so if you need it, you have to manually call the
SaveUserParamters
(0x03) function or the previous IP will
be reloaded at the next power-up.
Warning:
Do not use the “
SOS IP address
” as the normal IP for your module
(during normal board operation), because if you plug another
module on the same network, they will have the same IP and
therefore it will be impossible to configure both of them.
