The ETHERNET TCP/IP fieldbus coupler supports a number of network proto-
cols to send process data via ETHERNET TCP/IP. By observing the relevant IT
standards, connection to existing local or global networks (LAN, Internet) is
possible without any problem.
Using ETHERNET as a fieldbus makes universal data transmission between the
factory and the office possible. Moreover, the ETHERNET TCP/IP fieldbus
coupler offers remote maintenance, i.e. processes can be controlled regardless
of the location.
Process data exchange is done using the MODBUS/TCP protocol. The
buscoupler supports all I/O modules and automatically configures, creating a
local process image.
The HTML pages that are stored in the fieldbus coupler allow access to infor-
mation on configuration, status, or I/O data of the ETHERNET TCP/IP fieldbus
coupler. Only a standard WEB browser is required.
Dynamic configuration of the IP addresses via a BootP server provides a flexible
and easy way to configure the network.
