4.1 Mobile radio interface
The unit has a mobile radio interface for mobile data transmission.
The unit supports the 4G mobile network. In order to achieve higher network coverage, the unit has a
fallback function, allowing it to switch to the 2G or 3G network.
The unit detects the mobile network with the best transmission speed and automatically switches to it.
The mobile radio interface supports bidirectional data exchange in the mobile network.
4.2 eSIM card
The unit is equipped with an embedded SIM (eSIM) card. The eSIM card is delivered with an eSIM
profile that contains all the necessary communication settings.
The eSIM card of the unit is not activated on delivery. After registering the unit, activation of the
eSIM card can take up to 4 hours.
4.3 Connection modes
The unit can be operated in the following connection modes:
• Real-time mode
• Cloud logging mode
• IoT mode
The connection mode is set as follows:
Object Index Subindex Type Default Description
DeviceMode 0x1011 0x01 U8 0x03 0X00 = cloud logging mode
0x01 = reserved
0x02 = real-time mode
0x03 = IoT mode
Restart the unit to update to the newly configured mode.

When bit 7 is written, the unit restarts.
4.3.1 Real-time mode
In real-time mode, bidirectional transmission of CAN messages occurs.
The unit can send/receive process data (e.g. machine parameters) via CAN interfaces during
operation via the mobile network and the mobileIoT platform. Depending on the design, it can transmit
data from the GNSS receiver and the input/output functions and forward them via the CAN bus.
The data is continuously transmitted and can be evaluated in near real-time. For this function, there
must be a permanent connection between the unit and the user software or the mobileIoT platform.
This mode also supports a real-time connection from Codesys 2.3. This requires appropriate software
and a mobileIoT data contract.
The real-time mode can be set locally via an SDO or via the mobileIoT suite in the machine properties.
In real-time mode, no data or messages are stored on the mobileIoT platform.
4.3.2 Cloud logging mode
In cloud logging mode, selected CAN messages are sent to the cloud, processed and stored. In this
case, the unit operates autonomously and does not have to be actively controlled by an application.
The configurations for this mode are made in the mobileIoT suite, which can send the data in CAN
messages. An OTA (over-the-air) configuration of the units is carried out via the mobileIoT suite.
4.3.3 IoT mode
The IoT mode is a combination of real-time mode and cloud logging mode. It makes it possible to
establish a real-time connection with the CAN bus and automatically send GNSS position data to the
mobileIoT platform. In this mode, metrics are actively generated and sent by the application controller.
Data linking to the application controller is configured in the mobileIoT suite. There the corresponding
source code will be automatically generated, which can be loaded into the controller programme.
No data is sent to the mobileIoT platform during real-time connection. As soon as the real-time
connection is terminated, data is captured again and sent to the mobileIoT platform.
4.4 Input/output functions
The unit has additional input/output functions (3 analogue inputs, 1 digital output). For example, the
input function can be used to collect device or machine status information or to directly detect and
monitor switch states. The data determined via the input/output functions can be visualised or
transferred via the CAN bus.
The input/output functions are accessed via the following objects:

0x1011 0x65 The default configuration of the current firmware is restored.
All recorded data and settings are deleted.
The factory configuration is retained.
To carry out the factory reset via the CAN interface, CANopen software (e.g. maintenance tool) and a
communication gateway (e.g. CANfox, part no. EC2112) are required. The CANopen software writes
the value 0x64616F6C into the CANopen object index 0x1011 to trigger a specific reset variant.
The following example shows the factory reset via the sub-index 0x65 (restoration of the default
configuration):
uConnect the unit with a PC. Connect the unit (Ò/19).
uStart the CANopen software.
uWrite the value 0x64616F6C into the object index 0x1011, subindex 0x650 via the CANopen
software.
uWrite the value to the object dictionary of the unit.
uWait until the unit sends the CANopen boot-up message on COB-IDs 0x727 and 0x728.
wThe unit is reset to the firmware default settings (object 0x1011 0x65).
wThe ON LED lights green.
wThe STATUS LED lights blue.
wThe unit has adopted the firmware defaults (baud rate 250 kbit/s, node ID 39 etc.).
