Fig. 26: FOUNDATION Fieldbus system architecture with associated components
FF-HSE High Speed Ethernet
FF-H1 FOUNDATION Fieldbus-H1
LD Linking Device FF-HSE/FF-H1
PS Bus Power Supply
SB Safety Barrier
BT Bus Terminator
The system can be connected in the following ways:
– A linking device makes the connection to higher-order fieldbus levels (e.g. High Speed Ethernet (HSE)) possible.
– An FF-H1 connecting card is needed for direct connection to a process control system.
Further information on FOUNDATION Fieldbus can be found in Operating Instructions
