PROFIBUS Communications Handbook
PROFIBUS-DP is a multimaster, master-slave, token passing network. More detailed information, including a detailed guide
to products available, may be obtained from the various world wide PROFIBUS user organisations. You will find contact
information in trade magazines or by reference to http://www.profibus.com on the World Wide Web.
PROFIBUS is available in two other types, aimed at different application areas, as follows:
PROFIBUS-PA is designed especially for process automation. It permits sensors and actuators to be connected on one
common bus line even in intrinsically safe areas. PROFIBUS PA permits data communication and power over the bus, using
intrinsically safe, 2-wire technology according to the international standard IEC 1158-2, but may also be used on the standard
RS485 cabling for non-intrinsically safe applications.
PROFIBUS-FMS is the general purpose solution for communication tasks at the cell level.

series controllers may be used on ‘combi’ networks which combine DP and FMS, but may only be used for PA when
the intrinsically safe physical medium is not used.
