Configuration
The Ethernet interface X1P1 of the RTU is used for local connection of the configuration PC
or an external router for communication with the master station. It is not suitable for
connecting larger networks.
Configuration of the Ethernet interface
In this tab you will find the most important data of the Ethernet interface:
● MAC address
● Connection status
Connection status to the Ethernet network
● Transmission properties
Transmission speed and direction dependency (default: 100 Mbps, full duplex)
● Connected since (dd:hh:mm:ss)
● IP address
Shows the preset, last configured or the last IP address to be obtained from the DHCP
server.
● Subnet mask
Shows the preset, last configured or the last subnet mask to be obtained from the DHCP
server.
● Default router
Shows the configured IP address of the router being used or the one last obtained with
DHCP.
● DNS server
Shows the configured IP addresses of the DNS servers in the network or last obtained
with DHCP (max. 2).
Note
No address check
The RTU does not check the address bands. If If a duplicate IP address is detected, the
STATUS LED flashes red and the RTU is no longer reachable via the Ethernet interface.
Network settings when using OpenVPN
If you use OpenVPN, make sure that the LAN subnet of the RTU and the OpenVPN subnet
do not overlap otherwise no connection can be established to the RTU via OpenVPN.
Since the network settings of the OpenVPN server are not always precisely known, we
recommend that you set the LAN subnet to 255.255.255.0 when using OpenVPN.
