Brief description 8/292
2 Brief description
Hilscher's netIOT Edge Gateway NIOT-E-TIJCX-GB-RE securely connects
Real-Time Ethernet automation networks with a „Cloud“ or any IoT-directed
application.
As a field device, it is performing a cyclic I/O data exchange with the PLC
and communicates with further IoT-capable field devices within the
automation network.
These key field data exchanged in real-time form the basis for intelligent
higher-level IoT applications for cyber-physical processes and M2M
solutions.
The gateway is designed for continuous operation in environments with
permanent intranet or Internet connection. Security mechanisms such as
the physical separation of automation and IT network, a secure operating
system, the execution of signed firmware and packets, as well as
encryption techniques of the latest standards secure the data integrity and
offer protection against data theft.
The gateway base function forms the web-based Thing Wiring editor Node-
RED, which serves to model the flows in the devices. Data apps and data
profiles are created within minutes with predefined function blocks of the
editor. OPC UA and MQTT functions address objects in IoT-capable field
devices or in the cloud via standardized IoT protocols.
The Hilscher netIOT Service offers additional software packets to extend
the Edge Gateway base functions by further applications or accesses to
specific clouds.

Brief description 9/292
The open source software „Docker“ by Docker, Inc. allows the user to
execute own applications on the secured Linux operating system of the
Edge Gateways while all protection mechanisms are fully preserved. The
applications are executed in protected, isolated runtime environments. To
accomplish this, Docker uses special techniques from virtualization of
operating systems.

4.2 LED sticker
Each fieldbus system uses its own names for the LED displays. Therefore,
an LED sticker with the names of the respective fieldbus system is included
within the delivery of the Edge Gateway. Stick the sticker of the fieldbus
system to be used to the I/O shield of the fieldbus interface of the Edge
Gateway.

4.4 LAN connectors
The Edge Gateway has two LAN connectors for connecting it to the cloud
network, positions (7) and (5) (see section Positions of the
interfaces [}page10]).
The MAC addresses of the LAN interfaces are printed on the device label.
Section Configuring Ethernet communication (LAN) [}page64] describes,
how you can set the IP address parameters of the LAN interfaces.
4.5 Real-Time Ethernet connectors
The Edge Gateway has 2 RJ45-connectors to connect the fieldbus to a
Real-Time Ethernet network (OT network), positions (15) and (13) (see
section Positions of the interfaces [}page10]).
For data exchange at the fieldbus, use the fieldbus input and output in node
Node-RED. Sections Example 4: Fieldbus input node [}page138] and
Example 5: Fieldbus output node [}page146] describe how to access the
cyclic I/O data of the fieldbus in Node-RED.
4.6 USB connectors
The Edge Gateway has 4 USB connectors (1), positions (6) and (8) (see
section Positions of the interfaces [}page10]).
You do not need the USB connectors for operation of the Edge Gateway.
You need the USB connector if you connect a keyboard in order to change

4.7 Serial interfaces COM1 and COM2
The Edge Gateway has 2 configurable serial interfaces COM1 (position (9))
and COM2 (position (10)). You can use each serial interface as RS-232,
RS-422 or RS-485 interface.
Prerequisites
You have to set the interface type in the BIOS. For this, you need a
keyboard with USB connector and a monitor with DVI-I or DP connector.
Important:
NUse only 1:1 DVI or DP connectors. Adapters like DVI-I to VGA or
DP to VGA are not supported by the gateway.
BIOS settings
In the BIOS, select Advanced > IT8786 Super IO Configuration > Serial
Port 1 Configuration for COM1 or Serial Port 2 Configuration for COM2.
Serial Port Configuration Parameter
Serial Port Enabled
Disabled
Device Settings Display only
Serial Port 1 (COM1): IO=248h; IRQ=5
Serial Port 2 (COM2): IO=2F8h; IRQ=3
Onboard Serial Port Mode RS232
RS422
RS485 (do not use this setting)
RS485 Auto (use this setting for RS-485 only, because RTS
control is active)

4.8 Wi-Fi
The Edge Gateway NIOT-E-TIJCX-GB-RE\WF (article number 1321.301)
is equipped with a Wi-Fi interface. It supports 2 Wi-Fi operating modes:
Access Point and Client. Operating mode Access Point allows the Edge
Gateway to connect to other Wi-Fi devices in order to configure the Edge
Gateway from a mobile device for example. Operating mode Client allows
the Edge Gateway to be connected to any Wi-Fi Access Point.
Section Configuring wireless communication (Wi-Fi) [}page67] describes
how you activate the antennas and how to set the Wi-Fi operating mode.
4.9 Preparing gateway for cellular communication
The NIOT-E-TIJCX-GB-RE\4EU gateway (article number 1321.302) is
equipped with a cellular modem for transmitting data into the cloud via
2G/3G/4G standard.
Requirements
To use the cellular interface of the gateway, you require the following items
(not included in the delivery of the Edge Gateway):
·Contract for mobile data with mobile communications provider
·SIM card of provider with registration credentials (SIM-Pin, password
etc.)
·Two GSM/UMTS/LTE antennas with the following recommended
characteristics (passive):
– Direction: omnidirectional
– Gain: > -3dBi (Avg)
– Input impedance: 50 ohm
– Efficiency: > 50%
– VSWR: < 2
– Connector type: SMA plug
Note:
If you are using the older GSM (2G) standard only, a single (main)
antenna is sufficient.

ØPlace the SIM card into the tray. If necessary, use an adapter to fit a
Nano or Micro SIM format into the Mini SIM format of the tray:

ØRe-attach the cover of the card holder slot.
Connecting the antennas
Note:
Recommended type and positioning of your antennas depend on
the quality of your local radio signal.
If your Edge Gateway is stationed inside a control cabinet, you
should place the antennas outside the cabinet and connect the
antennas via cable to the SMA sockets of the gateway.

Connectors and mounting 20/292
ØConnect both antennas to the SMA sockets of the gateway:
Figure11: SMA sockets
Note:
If you are using solely the older GSM (2G) standard, you need only
one antenna, which is to be connected at the "main" interface of the
two SMA sockets. For identifying the main antenna interface on the
gateway, see section Positions of the interfaces [}page10].
4.10 Monitor connectors
The Edge Gateway has a DVI-I and a DP connector to connect a monitor.
You do not need a monitor for „normal“ operation of the Edge Gateway. If
you want to change settings in the BIOS or want to do a firmware recovery,
you need a monitor.
Important:
Use only 1:1 DVI or DP connectors. Adapters like DVI-I to VGA or
DP to VGA are not supported by the gateway.
