Reset Status - ICP DAS USA tM-TH8 User Manual

A.4 Reset Status
The reset status of a module is set when the module is
powered-on or when the module is reset by the module
watchdog. It is cleared after the responding of the first
$AA5 command. This can be used to check whether the
module had been reset. When the $AA5 command
responds that the reset status is cleared, that means the
module has not been reset since the last $AA5 command
was sent. When the $AA5 command responds that the
reset status is set and it is not the first time $AA5
command is sent, it means the module has been reset and
the digital output value had been changed to the power-on
value.
