Ethernet interface

General information
To use the Ethernet interface, a patch/crossover cable is required that is equipped with a RJ45
plug. The Ethernet interface is configured in the setup software.
Required parameters, such as DHCP functionality, IP address, sub-net mask, gateway ad-
dress, DNS device name, DNS server, and transfer rate, can be configured in the setup pro-
gram under P
The following transmission options can be used via Ethernet:
• Modbus/TCP as the slave provides third-party masters as servers
• Modbus/TCP as the master for reading/writing individual values or entire data frames
• Data transmission using HTTP protocol
• Sending e-mails using SMTP protocol
The DHCP and DNS protocols are also supported. You do not have to obtain a dynamic IP ad-
dress via DHCP; instead, you can manually assign a fixed address using the setup program. If
DHCP is used, the DNS functionality can be used. The device registers itself with the DHCP
server using a unique name. It can be uniquely addressed using this name. A DNS device
name is then used for addressing.
DNS should also always be used in combination with DHCP, since otherwise the device can no
longer be accessed via Ethernet if the IP address is changed.
