ABB UNO-DM-3.3-TL-PLUS Product Manual page 99

In order to use the "Host Name" as an alternative to the dynamic IP address, the Wi-Fi router
to which the board is connected (when operating in "Station Mode") must provide the Domain
Name System (DNS) service (contact the network administrator for further information regar-
ding the presence or absence of the DNS service in the Wi-Fi router or how to enable it). In this
way, even if the IP address assigned to the inverter should change over time, (dynamic IP), it
will always be possible to use the same "Host Name" which will remain unchanged over time.
The IP address assigned may vary for reasons connected to the wireless home router setup
(for example, a very brief DHCP lease time). If verification of the address is required, it is
usually possible to obtain the client list (and the corresponding IP addresses) from the wireless
router administration panel.
The most common causes of losing connectivity might be: different wireless network pas-
sword, faulty or unreachable router, replacement of router (different SSID) without the neces-
sary setting updates.
Once the tablet/smartphone/PC device is switched to the
domestic wireless network a new message will confirm
that the connection is acquired. (the WLAN board auto-
matically disables its access point network with the name
ABB-XX-XX-XX-XX-XX-XX that it is no longer necessary).
The message provides the links corresponding to the IP
Address assigned by the home wireless network router to
the inverter and the "Host Name": both links can be used
each time you want to access the internal webserver, with
the inverter connected to the home wireless network. Take
note of them.
Click on "Next" button to proceed to the next stage of the
configuration wizard (The device will automatically routed
to the link previously provided).
If the inverter loses the connection with the home wireless
network (and therefore, loses the internet connection), it
will once again enable its own access point.
