3.3.4 System redundancy with AXC 1050 or AXC 1050 XC
Figure 3-5 shows an application example of system redundancy. In the example, two
RFC 460R PN 3TX controllers connected via a fiber optic synchronization connection
(SYNC) form the higher-level redundant control system. The higher-level control system
controls a lower-level PROFINET ring network that is configured as redundant using the
MRP Media Redundancy Protocol. In the example, the AXC 1050 controller operates as a
PROFINET device with control function and is connected to the PROFINET network via a
switch.
Identical application programs run on both higher-level PROFINET controllers. In the exam-
ple, controller A is the FIRST PROFINET controller and controller B is the SECOND
PROFINET controller. Which of the two controllers controls the process depends on the re-
dundancy role (PRIMARY/BACKUP) of the controller, which may change depending on the
redundancy status.

dancy using MRP
For additional information on redundancy, please refer to the UM EN RFC 460R PN 3TX
user manual and the AH EN APPLICATIVE SYSTEM REDUNDANCY application note.
