The Westermo Fieldbus devices are industrial PROFIBUS DP modules.
There are different types of slave modules and one Master module.
PROFIBUS adapters that is able to transfer PROFIBUS DP I/O data via serial communication. I.e
leased lines, dial up modems, Ethernet adapters, GSM modems or radio modems without any
use of special drivers or special PLC bords.
The FD-20, PROFIBUS DP Master module act the same way as the adapters on the serial side and
act as a stand alone master on the PROFIBUS side. A combination with our Ethernet adapter
gives the opportunity to connect PROFIBUS to Ethernet PROFIBUS DP converter to make a
transparent connection for a different serial interfaces to a PROFIBUS DP network.
