UFS8000 Ethernet 70
14.1.3. Subnetmask
In the window the subnetmasker is entered after “NM”.
This generally has to be set as 255.255.255.0, showing that
the first 3 numbers of an IPaddress, within the network, have
to be the same and the final number has to be unique.
14.1.4. Default gate-way
In the window the address of the standard gateway is entered
after "GW”.
The address has to be set in the IP address of the appliance
(router or modem, for example) connecting the network with
another network (such as the internet).
14.1.5. HTTP port number
The port number 80 is routinely used for the
internet (World Wide Web).
The port numbers 1 to 1023 are officially
reserved but may be set, if necessary.
The port number may have to be changed if, for example, 2 controllers are placed behind a
modem or router that both have to be accessible via the internet. In the router or
modem another port has to be earmarked for both controllers.
A corresponding port number then has to be entered in the window.
If a port number other than port 80 is used then a colon and port number have to be entered in the
browser's URL bar, after the IP address or domain name. For example: 198.162.0.10:1024 for the use
of port number 1024.
Attention!
The changed port number becomes active only if the controller is switched off and
switched on.
14.1.1. Modbus
On the Ethernet port there is a Modbus compatible function available.
Here you can set the Modbus protocol, portnumber and de device address for the Modbus function in
the network. See § 21 “Modbus” at page 88 for more information.
14.2. Access via internet (WAN)
Here it is indicated how the modem can be set to be granted access to the controls via the internet
(WAN). It further describes how the IP address of the modem can be traced on the internet.
