2.2.4 Emergency Stop
In the event of a short circuit connection of DI1 and M, the Gateway will start the emergency
shutdown function.
Logic description of emergency stop: The Gateway uses continuous polling (*4) to obtain the
information of the connected device. During the effective period of the emergency stop function, the
Gateway determines that the IDU is locked in on the state according to the polling information, and
will unlock the locked-on attribute of the corresponding IDU.
If the IDU is on, the Gateway sends a shutdown command until the Gateway exits the emergency
stop function (*5).
*4: The interval of Gateway polling depends on the number of devices connected, and usually takes
ve minutes to complete.
*5: Exiting the emergency stop will not restore the IDU's locked-on status, namely, the IDU which
was originally locked on becomes unlocked.
