11.1.1
Replacing the controller
The controller can be replaced, if necessary.
To replace a controller, proceed as described in
Section 10, “Removing hardware”
Section 5, “Mounting hardware”
WARNING: Unintentional machine startup
If you replace the controller while the power is connected, this could result in uninten
-
tional machine startup and possibly cause personal injuries.
• Disconnect the power to the controller before replacing it.
• Before starting the system, ensure that the device or system does not present any
danger.
Removing the controller

•
Remove the supply connectors from the controller.
•
Remove the Ethernet connectors from the controller.
•
Remove the FO cable and the SFP module.
•
Remove the controller.
•
If operating the controller with a fan module:

ler
•
If you were operating the old controller with a fan module:
Mount the fan module on the new controller.
•
Mount the controller.
•
Insert the SD card from the old controller in the new controller.
Please note:
If the new controller firmware is of a later version than the firmware of the controller to
be replaced, you may have to recompile the project in the PLCnext Engineer software
and/or in the integrated development environment.
•
Connect the Ethernet connectors to the desired Ethernet interfaces on the controller.
•
Connect the SFP module and the FO cable.
•
Connect the power supplies.
•
Switch on the power supplies.

When the RFC 4072R is fully initialized, both controllers are synchronized with each
other via the SYNC interface.
