HMI@Web
Connection of the VCS control unit
with the HMI@Web to the LAN
Warning
If the VCS (controller) cannot be directly connected to the
LAN due to its default IP address settings and when a differ-
ent address range is used in the LAN network (e.g., 10.0.0...,
192.168.10...), or if there is already a PC in the network with
the assigned IP address ...199 (which can be verified using the
"ping + IP address" command) that needs to be preserved,
you need to perform the following steps to change the VCS
(controller) IP address settings.
If you are not an administrator of the LAN network, you
will have to contact your LAN administrator. The same
applies if you are not an administrator of your computer.
Using the Ethernet cable (not included in the HMI@Web
delivery) connect the HMI@Web unit to the LAN network
connecting point in the same way as any other LAN device.
The same conditions as in step 1 (connecting points, cable
lengths) apply for connection to LAN. To set the addresses, it
is possible to use other controllers like HMI SG, TM and DM.
Maximum VCS (controller) unit distance from an active
network element must comply with the Ethernet network
conditions.

To enable HMI@Web control, it is necessary to set a unique
IP address on the VCS controller within the address range of
the specific network. Please refer to the figure and set the
IP address under the " u LAN Connection" section (as
described in step 4: Activation).
Always restart VCS unit after assigning a new IP address – the
new setting is applied after restart.
Attention! Always consult with the network administrator
before connecting VCS with HMI@Web to the internal LAN
network.
2. Step: Computer Configuration - TCP/IP Settings
Warning
In this step, settings of the PC using Microsoft Windows®
are described; if you use other operating systems you will
have to perform corresponding settings of your computer in
accordance with your operating system user manual, or ask
an expert for help. This setting procedure is needed only for a
permanent direct connection to PC, or to change the HMI@
Web settings before its integration into the LAN network.

After setting the HMI@Web unit (following the below de-
scribed procedure), and when the HMI@Web default address
complies with network addressing, it is only necessary to en-
able new hardware in the infrastructure administration – there
is no need to make any other adjustments to individual PCs.
Adjust PC network card settings in Windows:
Go to "Start" >> "Settings" >> "Control Panel" >> "Network
connection"). Click (right mouse button) on "Local network
connection", then on "Properties", and display "Internet pro-
tocol (TCP/IP)" properties".
Figure 33 – TCP/IP settings
If the protocol is not found in the list of items (it is not installed),
add the item to the system. Click the "Install" button, select
the "Internet protocol (TCP/IP)", and follow the instructions
on the screen.
Select item "Use the following IP address". Type "192.168.1.3"**
into the "IP address" box and "255.255.255.0" into the "Net-
work mask" box. Do not type anything into the item boxes of
the second part of the window (leave them blank).
If you are prompted by the system to restart, confirm the
restart immediately.
Connection, resp. TCP/IP Protocol Verification
To verify the settings and connection, type the HMI@Web
address into the URL box of the internet browser (the HMI@
Web system must be switched on); it should start functioning
in 0.5 – 3 minutes - the time needed to initialize the webserver.

After sending the request, and if the settings and connect-
ing are correct, the HMI@Web web server is ready to be
configured, and the login window is displayed on the screen
requesting the user name and password.
** For the last part of the IP address, you can use any number from 1
to 254, except for the number 199, which is assigned to the HMI@
Web control..
