Ethernet menus

Ethernet menus are accessed via the Communication level. Refer to Operating Instruction
Menu Comment
Web Server Submenu that allows the configuration of the built-in web server.
DHCP Select to enable or disable DHCP (Dynamic Host Configuration Protocol).
• Enabled – select if the IP Address is to be allocated dynamically by the network
• Disabled – select if the IP Address is defined statically
IP Address
Enter the IP Address to be assigned to the transmitter.
If DHCP is set to Enabled, it displays the DHCP assigned IP Address, if any.
The IP Address is used by the IP Protocol to distinguish among different devices.
The Address is a 32-bit value expressed with 4 values (0 to 255) each separated by a period (.)
Subnet Mask Enter a subnet mask to indicate which part of the IP Address is used for the network ID and which part is
used for the host ID.
Set each bit that is part of the network ID as '1's, for example: 255.255.255.0 indicates that the first 24
bits are for the network ID.
Default Gateway
Enter the IP Address of the Default Gateway (router) used to communicate with other networks.
Note: this setting is required only if the device and the PC running the web browser/FTP client are on
different IP subnetworks.
DNS IP Address Enter the IP Address of the DNS (Domain Name System) server available in the network. This is used for
the name resolution of IP Addresses.
Usually a DNS server is not needed for the device to successfully connect to a network.
Secure Connection Enable or disable the SSL/TLS (Secure Socket Layer/Transport Layer Security) layer to establish secure
connections over a public network with a web browser. When enabled, remote connections are
established after an authentication phase via a security certificate (explained later).
When Secure Connection is Enabled, it is necessary to configure the Port Number option accordingly.
When Secure Connection is Enabled the web protocol used is HTTPS, otherwise HTTP.
Disable Webserver
Select Enabled to allow remote connections to the device with a web browser
Port Number Configures the Port Number from which the transmitter listens for connections requests. This
configuration must be changed according to the configuration of the Secure Connection parameter.
Valid values are:
• 443: Secure Connection is enabled
• 80: Secure Connection is disabled
FTP
Submenu to configure the FTP functionality.
Port Number Configures the Port Number from which the transmitter listens for connections requests.
Disable FTP
Select Enabled to allow remote connections to the device with either an FTP client or a web browser
(Read Only access, in the latter case)
Secure Connection Enable or disable the SSL/TLS (Secure Socket Layer/Transport Layer Security) layer to establish secure
connections over a public network with a web browser. When enabled, remote connections are
established after an authentication phase via a security certificate (see Certificate management and
storage, page 8).
Security Certificate Submenu for the security certificate creation and renewal – see page 8.
First Provisioning Performs the first provisioning of the device. To be used when the device is expected to be Inter-net
facing.
This option performs the following operations:
• Provisioning of the AWT420 internal HSM
• Creation of the Device Identifier
• Creation of the first self-signed digital certificate to be used during the secure connection
After this operation is completed, the device is ready to be connected to the Internet. The digital
certificate lasts 3 years.
Certificate Renew Performs the renewal of the device's digital certificate. To be used after expiration of the current one.
See page 9 for more details.
Device Identifier
Displays the Device Identifier. This value is reported also in the digital certificate sent to the web
browser during the secure connection establishment. It is expressed as a 16-bit hexadecimal value
(e.g. BE1D). It is unique to the device. See First Provisioning, page 9 for details.
User Name Allows the configuration of the web server and FTP server user.
Password
Allows the configuration of the associated password to access both the web server and the FTP server.
The user/plant administrator is advised to change the default password upon device commissioning to
restrict access to authorized personnel only.
MAC Address Shows the MAC Address of the Ethernet device. This value is read-only.
