Architecture
When operating with multiple segments and Fuchs couplers the component
architecture might be as for example as shown in Fig. 4.2. For simplicity the devices
connected to Segments
2 – 5 are not shown. All Fieldgate SFG500s are connected to the Ethernet backbone via the
LAN 1 Ethernet socket and share a common Ethernet IP address domain. One Fieldgate
SFC500 is connected to each PROFIBUS DP segment. The PROFIBUS DP segments do not
necessarily have to be connected to a single PLC. PROFIBUS PA devices are connected to the
PROFIBUS DP segments via couplers.
