3.3.4 System redundancy with the AXC F 1050
Figure 3-5 illustrates an application example for system redundancy. In the example, two
RFC 460R PN 3TX controllers connected via a fiber optic synchronization connection
(SYNC) form the superordinate redundant control system. This superordinate control sys-
tem controls a subordinate PROFINET ring network that is configured as redundant using
the Media Redundancy Protocol (MRP). In the example, the AXC F 1050 controller oper-
ates as a PROFINET device with control function and is connected to the PROFINET net-
work via a switch.
Identical application programs run on both superordinate PROFINET controllers. In the ex-
ample, 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.

dundancy 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.
