Redundant Route Control servers
SIMATIC Route Control allows you to implement two Route Control servers with redundancy
functionality for high availability operation. This ensures that you can monitor and control your
route control at all times.
Functionality
The Route Control software automatically takes over the monitoring of the redundancy. The
redundant Route Control servers monitor each other in runtime.
If one of the two Route Control server fails, the process can be controlled via the second Route
Control server following switchover.
The Route Control clients automatically fail over to the functioning (active) Route Control
server.
When the failed Route Control server resumes normal service, it retrieves the current process
image from the automation system.
During the failure, the functioning Route Control server automatically receives the internal
Master ID. If the active master server failed, the master ID is passed from the failed Route
Control server to its Route Control partner server.
When the failed Route Control server becomes available again, it is given the standby ID. The
master ID remains with the Route Control partner server.
Configuration of a redundant Route Control server
The following configuration shows the basic operating principle of redundant Route Control
servers.
