4 Product Description
The IM18-CCM50-MTI/24VDC cabinet guard is enclosed in a plastic housing with protection to
IP20 and is provided with three multicolor status LEDs. Two Ethernet ports are provided for
connection to higher-level systems. External sensors can be connected to the device via a CAN/
RS485 port. The Ethernet interfaces and the CAN/RS485 interface are implemented as RJ45
sockets. 3-pin spring-loaded terminals are provided for connecting the power supply, relay out-
put, analog input and GPIOs.
The device is provided with a distance sensor as well as a temperature and humidity sensor.
The Linux Debian operating system is preinstalled on the device. The device functions must be
programmed as required.

4.3 Operating principle
The ambient temperature and humidity are monitored by a humidity and temperature sensor
and the door status is monitored by a distance sensor. The device communicates with the
higher-level system via the Ethernet port.
4.4 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 via Ethernet to higher-
level systems.
The following interfaces are provided on the device:
n2 Ethernet interfaces
nCAN/RS485 interface
n2 GPIOs
n2 analog inputs (configurable as current or voltage input)
nChangeover contact relay
nUSB interface
The operating system provided on the device is the Debian Linux distribution. This enables the
smart preprocessing of data through the integration of tailored programs. The device functions
can be programmed as required.
4.4.1 System partitions and recovery system
The device is provided with two operating system partitions and a recovery system. If one sys-
tem partition is damaged or an update fails, the partitions make it possible to revert to the pre-
vious executable system. A recovery system is started in the event that both system partitions
fail. The recovery system resets the device to the factory settings.
4.4.2 Ethernet interfaces
The device is provided with two Ethernet interfaces ETH0 and ETH1.
The ETH0 interface is a 1 GbE interface in accordance with 1000BASE-T for connecting to
higher-level storage systems or cloud services.
The ETH1 interface is compliant with the 100BASE-TX standard. The transmission speed is
100Mbit/s. The ETH1 enables the device to be connected to an industrial Ethernet network.
The Ethernet interfaces are set for dynamic addressing via DHCP. The following default IP ad-
dresses are also available:
nETH0: 192.168.1.20
nETH1: 192.168.2.20
The max. cable length is 100 m.
4.4.3 CAN/RS485 interface
External devices can be connected to the cabinet guard, e.g. sensors for condition monitoring.
The sensors can be connected for example via Modbus RTU or CAN. The corresponding bus ter-
minals are integrated in the cabinet guard. The CAN/RS485 interface provides a nominal
voltage of 24 VDC for the supply of the external devices.
4.4.4 GPIOs
The GPIOs can be configured separately as digital inputs or outputs. Additional sensors can be
connected to the GPIOs. Simple shell scripts are provided on the system as support for the con-
figuration.

Product Description
10 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.4.5 Analog inputs
The two analog inputs can be configured separately as current inputs (0…35 mA) or voltage in-
puts (0…5 V, 0…10 V or 0…20 V). Additional sensors can be connected to the analog inputs.
Simple shell scripts are provided on the system as support for the configuration.
4.4.6 Relay
The device is provided with a changeover relay for connecting resistive loads. The load capacity
is 48V/0.5A for 100000 switching cycles. Limit value violations can, for example, be forwarded
as switching signals via the relay output. Simple shell scripts are provided on the system as sup-
port for the configuration.
4.4.7 Trusted Platform Module Controller (TPM controller)
The device is provided with a trusted platform module controller (TPM controller) in accord-
ance with the TCG specification (TCG TPM 2.0). The TPM controller allows the possibility of addi-
tional safety functions, e.g. when using the device for license and data protection require-
ments.
4.4.8 USB Host interface
The USB Host interface makes it possible to access the device, e.g. for expanding the memory
with a USB stick. The USB Host interface is implemented as a USB 2.0 high-speed interface. The
USB interface is protected from unauthorized system access by the Linux tool USBGuard. Ac-
cess to the device via the USB interface is only possible for allowed USB devices.

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).
NOTICE
