With the above programming the systems will automatically integrate and the cards will be reset when they
are idle. If the network is lost, the systems will revert to stand alone systems.
System A (172.16.0.10) will always be the Primary System when the network is up.
If Top Priority system is not available in the network, Primary System is elected by highest Primary
Candidate Priority (lowest number). If this value is equal on all systems then the lowest Node ID will be
elected as the Primary.
After programming NetLink, on exiting programming you will be asked if you wish to reset the system.
Always choose yes otherwise the NetLink programming may be lost.
Example 2
With the programming below the first system to be powered on will be the Primary System. This is
because the systems are not set to look for a specific IP address to be the Primary and when the first
system is powered on there are no other systems available to be the Primary. When the other two systems
are powered on they do a search and find there is already a Primary System so they accept that. If the
network is lost, the systems will revert to stand alone systems. When the network comes back up, nothing
will change automatically, NetLink will not be operational. Enforced Primary Integration can be used (if
enabled), or the Secondary systems can be reset to bring NetLink back up again.
