3.10 Factory resetting XC-104-… and XC-204-…
There are two ways to carry out a factory reset:
1. Factory reset with the Web Config Tool
2. Factory reset through the USB port
Use the first method if you know the access information for the device, as
this is the fastest of the two options – please refer to ￫ Section “14.4.5
Factory reset”, page 142.
You can use the second method if you do not know the password for the
device. However, this method requires the preparation steps outlined below.
Method 2: Factory reset through the USB port
To do so, follow the steps below:
▶ Make sure that the "Enable USB factory reset" switch is enabled (i.e., in
the right-hand switch position) on the Device configuration page in Web
Config Tool.
▶ Prepare a storage device with a USB interface and store a file named
"factory-reset.txt" on it.
▶ The only content of this file should be the device's serial number, e.g.,
"100000001098".
▶ Make sure that the device is de-energized.
▶ Plug the storage device into the device's USB port.
▶ Switch on the power supply at the device.
As soon as the storage device is connected to the device through the USB
port and the device is switched on and starts booting up, the device will
check whether the "factory-reset.txt" file is found on the storage device and
whether the content of the file matches the device's serial number. If they
do, the device will be reset to its default settings.
The "factory-reset.txt" file will then be deleted from the storage device. The
"Enable USB factory reset" switch will be disabled, i.e., switched to the left-
hand switch position.
All Ethernet ports will be reset to their default settings. If a password has
been set, it will be deleted.
￫
The new firmware version will not be enabled until the PLC is
restarted.
