4.3 Functions and operating modes
The device uses integrated sensors to monitor temperature, relative air humidity and the dis-
tance to the control cabinet door. The information can be transferred to higher-level systems
via the Ethernet interface and Modbus TCP.
External sensors can for example be connected via Modbus RTU and the RS485 interface or via
CAN. The operating system provided on the device is the Debian Linux distribution. This en-
ables the smart preprocessing of data through the integration of tailored programs. The device
functions can be programmed as required.

The device is provided with two operating system partitions and a recovery system. If one
system partition is damaged or an update fails, the partitions make it possible to revert to the
previous executable system. A recovery system is started in the event that both system parti-
tions fail. The recovery system resets the device to the factory settings.

7 Commissioning
The device is operational automatically once the cables are connected and the power supply is
switched on. All LEDs are lit in several colors during the boot procedure. After the boot proced-
ure has been successfully completed, the Pwr LED flashes green at a frequency of 2Hz.
The Linux operating system enables the device functions to be programmed or scripts to be
imported. An SSH connection can be established once the device is connected to the network.
Additional software tools (e.g. PuTTY) are required to access the device via the console. The IP
address depends on the selected connection. The user sshu also has the possibility to use sudo
options.

7.1 Establishing a network connection
After a physical connection has been established, a ping command can be used to check
whether the device can be reached. An SSH connection to the device can then also be set up
using an SSH or SFTP client software (e.g. PuTTY, WinSCP or similar).

Hans Turck GmbH & Co. KG | T [phone] | [email protected] | www.turck.com V02.00 | 2022/09 | 20
10 Troubleshooting
10.1 Recovery system
NOTICE
Failure of both system partitions. Data loss possible.
The recovery system resets the device to the factory settings.
Take measures to prevent data loss.
The device is provided with two operating system partitions and a recovery system. If one
system partition is damaged or an update fails, the partitions make it possible to revert to the
previous executable system or recovery system.
The active system is marked as faulty after three failed boot operations in succession. The other
system partition becomes the active system.
The faulty system is first of all updated in an update operation. This increases the availability of
the system. If both operating system partitions are marked as faulty at the same time, a recov-
ery system is started. The recovery system automatically restores the device to the factory
settings. This resets all data in the other partitions to the factory settings.
