Control (HMI@Web – Connection to PC and LAN/WAN)
4th Step: How to Change the HMI@Web Controller IP
Address
The HMI@Web controller IP address for operation in your
network can be changed from the following page:
Connection >> LAN connection
Figure 37 – LAN connection settings
The lines allowing entries of values are marked with a red
button.
Once the button of the respective line has been activated,
enter the new value in the dialog box at the bottom of the
browser. Press the
the changes.
Progressively enter and save all the items "Enter ..." (Address,
Mask or Gate).
Finally, restart the HMI@Web controller using the option "Ap-
ply + Reset". After the restart, the device starts reporting on
the new address (once the initiation has been completed – it
takes about 3 minutes).** To resume communication (if the
network segment has been changed), it may be necessary
to readjust the network connection settings on your PC
so that they are compatible with the HMI@Web controller
(respectively LAN); the HMI@Web controller with the modi-
fied setting can be alternatively connected to the LAN. It is
necessary to enter the correct network address in the browser
to enable log-in.
5th step: LAN Connection Setting Warning
Any changes to the settings must be performed cautiously and
carefully at each step. Each modifiable parameter (Address,
Mask or Gate) must be carefully checked and saved separately.

Then it is necessary to send (plan) the change entry – after
that, the settings must be finished using the option "Apply +
+Reset". (Warning: Do not perform the restart by switching
off or disconnecting the device – when saving the changes
using the "Apply + Reset" option, the settings are simultane-
ously stored in an archive which is needed for restart of the
device after a power supply failure - otherwise, there is a risk
of uncontrolled changes to the settings.)
Note: Control start-up after device restart takes several
seconds – it does not to do anything with the Web Server
initiation. That is because of the standard start-up sequences
that are being performed during the connected air-handling
system start-up, i.e. opening of dampers, pre-heating and fan
start. We strongly recommend not using the configuration
with the address assigned by the DHCP server; instead, use
the fixed IP address.
Warning
If the IP address of the given device happens to get lost (e.g.
once the LAN setting have been changed) and it is not pos-
sible to establish the connection (no response to the "ping"
command, etc.), it is possible to use the HMI-DM or HMI-TM
controllers to set the required parameters and restart the
device directly.
Note: In extreme cases, the device can be looked up within
the network using the MAC address (indicated on the name
plate) – contact the network administrator.
Internet Integration
By connecting the WebClima system to the local network
via the above-mentioned setting of the IP address and au-
thorization of users, the basic (direct-interactive) monitoring
and operating possibilities within the local network or by PC
are enabled.
To enable access to the WebClima system via internet, it is
necessary to ensure direct access to the device from internet.
Notice: This is necessary especially if supervision (operation,
service) outside the company is required.
To connect your HMI@Web unit to the internet, contact
your network administrator.
