1. Introduction
The FD-80 Fieldbus Adapter Profibus DP slave, is a simple and cost effective way of
connecting different Profibus DP networks through Ethernet LAN with TCP/IP protocol.
The FD-80 can be configured to send the desired amount of data which is transparently
transferred between different Profibus DP networks via the Ethernet 10Base-T interface.
There are two different types of FD-80 devices:
• Point to point, the FD-80 (P) transfers continuously specified Profibus DP data from
the input/output buffers over Ethernet using TCP/IP.
• Addressed, the FD-80 (A) is the Ethernet TCP/IP master which exchanges specified
Profibus DP data with addressed remote FD-80 (P).The data frames include the
address of the selected remote FD-80 (P).
