COMMUNICATION

Enable Ethernet port

Tick the box if the Ethernet port will be used.

Enable UDP identification

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.
