The MODBUS/TCP(UDP) protocol and the Ethernet/IP protocol are implemented for exchanging
process data. The two communication protocols can be used optional or together.
For the management and diagnosis of the system, the HTTP, SNTP and SNMP protocols are available.
For the data transfer via Ethernet the FTP is available.
For the automatic assignment of the IP address in the network, alternatively DHCP or BootP can be
used.
An internal server is available for Web-based applications.
HTML pages stored in the head station allow access to information about the configuration, the status
and the I/O data of the fieldbus node via Web browsers.
Using the implemented file system, it is also possible to store individual HTML pages.
