An example of a distributed network
Algorithm of working in LAN
1.
If DHCP on (IP is 0.0.0.0) - obtaining IP address with the start of the
access control panel
2.
Update of IP status of address (announcement and extension of reserved
IP, if DHCP)
3.
Determine accessibility of ACS server and U-Prox IC A control panel (IP or
DNS name)
4.
Periodic sending of test signals
5.
If there is, sending of events. Waiting for server commands.
Algorithm of working on the Internet (local wire net)
1.
If DHCP on (IP is 0.0.0.0) - 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 and U-Prox IC A control panel (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.
