3.1.
Supported protocols
Depending on the model, SenNet dataloggers can have the following ports: RS485, Ethernet, RS232,
GPRS, HDMI, USB and radio frequency. The dataloggers can capture data from external devices that
have compatible interface. This can be done either via standard protocols, or via proprietary protocols
implemented in the device.
SenNet dataloggers are compatible with a large number of protocols. The main ones are listed below:
▪
Modbus RTU and TCP
for communication with electric meters, temperature sensors, weather
stations, photovoltaic inverters, gateways to third-party radio networks, etc.
▪
MBUS
for communication with electricity and thermal meters
▪
IEC870-5-102
for electricity meters
▪
DLMS/COSEM
for smart electricity meters.
▪
IEC 62056-21 / IEC 61017
for electricity meters
▪
KNX
for communication with home-automation equipment
▪
Zwave
for radio communication at smart homes
▪
Proprietary protocols
: Apart from the standard protocols, the dataloggers support specific
proprietary protocols developed by other manufacturers.
▪
Other protocols
…
Please, contact Satel Spain or your SenNet distributor for further information concerning compatibility
and protocols supported.
3.2.
Access to captured data
The data captured by the datalogger can be remotely obtained via:
―
Integrated GPRS module (only in models DL170, DL171 and DL172)
―
Optional 3G module (available for models DL170, DL171 and DL172)
―
External router, connected to the Ethernet port.
―
Wi-Fi (models DL150, DL151, DL170, DL171)
―
HDMI (models DL150, DL151, DL170, DL171)
The mechanisms offered by the datalogger to access the data captured are:
▪
Request mechanisms
(where the datalogger works as a server)
o
Webserver to see the latest data received and download files in CSV format
o
Modbus TCP for access from SCADA or BMS systems
o
XML to download the data in XML format
▪
Automatic delivery mechanisms
: (where the datalogger works as a client)
o
Sending CSV files with the data captured to an FTP server
o
Sending the data to a TCP-IP server:
▪
Via proprietary protocol, SenNet TLV
▪
Via specific web services used by energy management platforms.
▪
Using specific protocols for IoT platforms (Internet of Things), such as:
Carriots, BlauLabs, Sofia2, DynDNS, etc.
The mechanisms listed above may be concurrent, so that the same datalogger can be configured to
automatically send data via TCP-IP and via FTP, and simultaneously being asked via Modbus TCP.
In addition to the communication ports, some dataloggers include current measurement inputs to
connect current transformers (CT 0,33V) or Rogowski coils.
The DL170, DL171 and DL172 models also have the following inputs and outputs:
▪
3 inputs 8-30 Vdc
▪
4 outputs 8-30 Vdc @ 100 mA (max.)
