Point to point over Ethernet
The continuous transfer of defined PROFIBUS I/O data over Ethernet, between one
FD-10 P (fieldbus adapter PROFIBUS DP Slave) and one FD-20 (Fieldbus adapter
PROFIBUS DP Master).
This application is created by using one FD-10 P (point to point mode) and one
ED-10 UDP (Ethernet adapter) in the main PROIBUS DP network and one ED-10 UDP
and one FD-20 in the remote network.The FD-20 can support a number of
PROFIBUS DP Slaves

Master controlled transfer (Addressed)
The transfer of defined PROFIBUS I/O data between one FD-10 A controlled by a
PROFIBUS DP Master and several FD-20s.The FD-10 acts as serial transfer master
and can transfer I/O data between various addressed FD-20s.This solution is ideal
when a PROFIBUS DP Master needs to connect to two, or more, independent remote
PROFIBUS DP Slaves. A radio system, multi-drop modem or RS-485 bus is typically used
as the connecting medium.The serial data rate is independent of the PROFIBUS DP rate,
so each PROFIBUS DP network could run at different data rates to the serial backbone.
