1SenzaNET
SenzaGate is the central node of a wireless device network running the SenzaNET protocol. This
chapter gives a basic overview of SenzaNET, the devices involved, terminology and features.
1.1 Communication in SenzaNET
SenzaGate is the network master, responsible for all communication to/from the wireless network.
Hence, all communication to any network node is done through the gateway. This is possible either
via SenzaWMS, the SenzaNET programming interface or through Fieldbus interfaces.

1.2 Network Elements
1.2.1 SenzaBlock
SenzaBlock represents the basic component of SenzaNET. SenzaBlock has mesh networking
capabilities and can interface with devices (e.g. sensors, actuators) at the same time.
SenzaBlocksare available from E-Senza Technologies in different variations for a multitude of
applications.
As adapter-devices or built-in modules, they enable all kinds of sensor and actuator devices to be
controlled wirelessly and exchange data through a self-organizing wireless mesh network with ultra-
low power consumption.
1.2.2 SenzaGate
SenzaNET supports integration of the Wireless Network with existing systems or products through
SenzaGate. You always need SenzaGate as a network master to communicate to or from
SenzaBlocks. They not only support Network Layer functionality but also provide interfacing to
upper layers. SenzaGates are available for a multitude of industrial interfaces: Ethernet, Serial,
Modbus, Profibus etc.
SenzaGate SG151lite comes with Ethernet and ModbusTCP interfaces.
1.2.3 SenzaWMS
SenzaWMS is the software-suite accompanying SenzaNET. It provides a web-based user-interface for
administration of the wireless network and monitoring of each individual node.
With SenzaWMS, multiple networks can be managed in parallel, networked devices can be re-
configured, alarm messaging and data acquisition are automated. Comprehensive software-APIs and
data-export options allow seamless integration into existing IT-infrastructures.
SenzaGate SG151lite is designed as a standalone gateway and network manager and operates
without SenzaWMS. It provides functionality for managing the wireless network and the SenzaBlocks
connected to it as well as security functions. SG151lite acts as a Modbus-Slave device and maps
SenzaBlock status information and payload data onto Modbus registers for a Modbus master device
to read out and process further.

2SenzaGate SG151lite
SenzaGate SG151lite acts as Network Master in SenzaNET.
All configuration of the wireless network, the individual SenzaBlocks is done using the webpages of
SG151lite’s built-in webserver.
Setting SG151lite’s IP-address and TCP/IP network configuration is done through that same
webserver, too.
2.1 Installation
2.1.1 Electrical and Data Connections
SenzaGate is powered by an external 12 V power supply.
Connect the Ethernet cable now using standard RJ 5-connectors.
2.1.2 Antenna Connection
SenzaGate`s IP 0-enclosure comes with a reverse-SMA
antenna connector (“male”) and an applicable
antenna. Just plug antenna onto connector and turn it
in clockwise direction until it is fixed tightly. Loose
fixing of the antenna might affect RF-performance of
SenzaGate !

2.2 Accessin SenzaGate
SenzaGate SG151lite comes with the following default settings:
DHCP: Enabled SG151lite will attempt to obtain a dynamic IP-address
IP Address: 192.168.0.126 Fallback-address, in case no DHCP-service service available
Subnet mask: 255.255.255.0
Gateway Address: 192.168.0.1 Ethernet gateway of your LAN
Administrator-Login admin
Admin-Password admin
User-Login user
User-Password user
Connect SG151lite to power and your local LAN network. Make sure you have the same subnet mask
and LAN gateway address.
SenzaGate has a built-in webinterface which can be accessed through webbrowser. The
webinterface is based on javascript and shell scripts. Your browser needs to have javascript
enabled.
B default the Gatewa will connect via DHCP, which means an IP-address will be assigned to
it b our network’s DHCP service. If DHCP is not available, SenzaGate will be accessible
through its default IP address. In a LAN-network with DHCP, SenzaGate can be forced to use
the default IP-address b unplugging the Ethernet cable during start of SenzaGate and plug it
in after 1 minute.
When an IP-address was assigned automatically to SenzaGate, use a network scanning tool to
identify this IP-address. There are various network scanning tools available for free download, e.g.
NetworkScanner® by SoftPerfect® (http://www.softperfect.com/products/networkscanner/).
The output of such a network scanning tool is a list of all devices found on the network showing
their IP-address together with their MAC-IDs. SenzaGate’s MAC-ID is printed on it’s product label, so
all you have to do is to lookup the MAC-ID in the list.

Manual SG151lite 8
2.3.4 Modbus Settin s
SG151lite works as a Modbus-Slave with Slave-ID=1 running the Modbus-TCP protocol. Modbus-TCP
physically runs over the Ethernet port, in parallel to the TCP/IP connection, which uses the same
physical port. The data coming from SenzaBlocks are mapped onto Modbus-registers for the
Modbus-masters to read them.
For Modbus-Operation, it is important to Disable DHCP and assign a fix IP-address to our
SG151lite, because the Modbus-Master must be able to find SG151lite at a pre-defined IP-
address
The following settings must be made to define the mapping of SenzaBlock-data onto Modbus-
registers:
Field Description Default
Start Address Start address for Modbus 0001
SenzaBlock Sequence List of SenzaBlocks to be mapped
onto Modbus-registers.
Each SenzaBlock occupies 25
Modbus-registers, see details below
001EAA0000000001
This configuration works with the MAC-ID of the SenzaBlocks.
After saving the new configuration, a reboot is required. This will not be done automatically.

Manual SG151lite 9
2.3.4.1 Modbus Interfacin
When SG151lite is configured as described in the previous chapter, you can start the Modbus Master
to read status and sensor data over ModbusTCP. As a Modbus Slave Device, SenzaGate will respond
to the Modbus Master’s read requests. The Master must send Modbus-Function 4 (0x04) – Read
Input Re isters with Slave-ID=1, Port=502 and the correct IP-Address of the Gateway. The return
values of the Modbus Slave are given as 16bit re isters as defined by the Modbus configuration. For
each SenzaBlock MAC-ID, 25 registers are reserved using the following layout:
Register 1-4: MAC-ID
Register 5: SenzaBlock Type
Register 6-11: Sensor Values
Register 12-13: Alarm Indicator
Register 14-19: Timestamp
Register 20: Battery Status 0 = Empty / 1= Full / 2 = ext. Power

The heartbeat shall be set in accordance with the sampling rate required for your application. Keep
in mind that this affects the battery lifetime of your SenzaBlocks: The shorter the heartbeat, the
shorter will your battery last. Get in touch with E-Senza for more detailed information and the
battery life that can be expected in your application.

2.3.9 Edit / Deny SenzaBlocks
Individual SenzaBlocks can be selected editing their settings or they can be denied access to the
wireless network using this webserver page.
Commonly, this page will be used to setup a SenzaNET during commissioning and you may want to
avoid any further SenzaBlocks taking part in network communication if they are not explicitely
allowed to do so. The “Auto-deny” function is intended for this scenario: After commissioning, it
shall be set to “Yes”, which will cause any new wireless node attempting to join the wireless
network being rejected.
