The controller also supports the DNS protocol (Domain Name System). The DNS system is a system
used for the conversion of the network knots names into IP addresses and vice versa.
The controller uses thi
s function to convert the server name “Si.Mo.Ne” into an IP address, but also to
sign up on the network with a name. The name has to be configured through P.0456 and must be
univocal in the network. To use the DNS system is required:

If you do not use a DHCP server (see above), it is necessary to set the IP address of the
DNS server in P.0510 (it is possible to set the address of a secondary DNS server into
P.0511).

If you use a DHCP server (see above), the IP address of the DNS server is received by
the controller directly through the DHCP server.
If the DNS server is reachable on the network, the controller provides to register its name (P.0456) on
the network, and since that moment it will be reachable through the TCP-Modbus protocol, both on
the IP address and on the configured names, on the P.0503 port.
The parameters P.0508 and P.0509 allows to set the IP address and the NTP server port (Network
Time Protocol), to be used to connect to a NTP server in such a way to keep the inner time and the
giv
en time zone synchronized and updated (that is UTC time “Coordinated Universal Time”). By setting
both the parameters to zero, the function will be disabled.
The real IP addresses (those configured manually or those obtained from the DHCP server) are visible
on page S.04.
Link LTE
Note:
refer to paragraph 1.1 - Nomenclature
The HS315
Link
controller is equipped with a LTE Cat.M1 and NB
‑
IoT Multimode module and
quad
‑
band 2G fallback ( GPRS/EDGE) with multi-regional coverage.
They embed also a Global Navigation Satellite System ( GNSS ) receiver, using GPS , GLONASS,
GALILEO or BeiDou system, to provide and reliable positioning information with a high accuracy
and performance.
The flexibility extends further with dynamic system selection as
Cat.M1, NB
‑
IoT , and
GPRS/EDGE in single mode or as a preferred connection that does not require a module reboot
to switch between modes. They provide a solution for applications that require broad geographic
coverage, even in areas where
LTE Cat.M1 and NB-IoT are not widely available yet.
New

devices deployed in the field today, can then be activated on existing 2G
networks and still leverage the benefits of LTE Cat.M1 and NB
‑
IoT technology once it becomes
available.
The system can be used for different purposes
