4.2 Ethernet
To ensure that a Modbus TCP connection can be established with the device, it is first necessary to adjust
the device's network settings (IP address, subnet mask and gateway). The settings depend on the network
into which the device is being integrated.
DHCP:
If a DHCP server is used within the TCP/IP network, the IP
address, gateway and subnet mask are set automatically when
the DHCP client function is enabled. The DHCP client function
is enabled when the measuring device is delivered. The DHCP
client function is activated by default, but can be disabled in
the "Ethernet settings" menu.
Software:
The network settings can be edited in the menu.
Hardware:
The low-byte of the IP-Address can be set with the DIP switch
located on the front of the 485/ETH module. The other parts
of the IP-Address are unchanged. This allows you to set the
higher 3 bytes using e.g. software addressing and the low-
byte by Hardware.
IP-Address of Gateway (optional)
The service switch is located on the module. While this switch
is in position “On”, the following network settings are active:
IP-Address = 192.168.1.212
Netmask =255.255.255.0
Gateway = 0.0.0.0
When returning the switch to “Off”, the original network
settings are restored.
The MAC address is imprinted on the communication module
or can be read via the menu. The MAC address of the
measuring device is used for identification purposes and is
uniquely and permanently assigned in the factory.
