Enable Ethernet port
Tick the box if the Ethernet port will be used.

Tick the box if UDP (User Datagram Protocol) is enabled: this allows
the Summit configuration software to automatically detect this
Summit on the Ethernet.
Please note that UDP may be blocked by company routers.
IP address
Set the IP address to be allocated to the flow computer
Netmask
Set a corresponding Netmask (e.g. 255.255.255.0).
Gateway
A gateway is the network device that enables data to enter and exit a
LAN, such as a router to a Wide Area Network. Leave at default if no
gateway is needed.
DNS Server
A DNS (domain name system) server manages the names of websites
and other Internet domains, such that you can type in a name instead
of an IP number to find a computer Internet. Leave at default if no
DNS server is needed.
Configuration software:
Enable
Tick the box if the configuration software is allowed to access this
computer
Port
Provide the Ethernet port address to be used by the configuration
software. The default port is 3000, but on some networks another port
may be more appropriate.
8 .3 Modbus master
In the Summit the modbus master is used to get information from metering devices. Tradition-
ally a serial port is used for devices and therefore each board has one or more serial ports.
Nowadays Modbus over TCP/IP becomes more popular, so the Summit also supports this on its
ethernet ports where for each Ethernet port 2 modbus masters are available.
