2.
Update of IP status of address (announcement and extension of reserved
IP, if DHCP).
3.
Determine accessibility of ACS server (IP or DNS name).
4.
Periodic sending of test signals.
5.
If there is, sending of events. Waiting for server commands.
Algorithm of operation on the Internet (local wire net)
1.
If DHCP - obtaining of IP address within local network affiliate at panel
launch.
2.
Update of status of IP addresses (announcement and extension of
reserved IP, if DHCP).
3.
Determine possibility of access to the Internet (accessibility of given IP
address of router).
4.
Determine accessibility of ACS server (IP or DNS name).
5.
Periodic sending of test signals.
6.
If there is, send the events. Waiting for server commands.
7.
Failure - transition to the second specified IP address of router.
System deployment
The use of the existing computer network infrastructure, standard network protocols
(DHCP for instance) allowed to provide the “plug-and-play” principle. The mode of
the automatic server address configuration in the panels eases the access system
deployment significantly.
