PROFIBUS
International (PI)
The international umbrella organization for PROFIBUS
founded in 1995.
PROFIBUS User
Organization e.V. (PNO)
The PNO is the trade body of manufacturers and users
for PROFIBUS founded in 1989.
Redundancy The existence of more than one capability of an item
(system, equipment or component) to perform its
intended function.
Remote I/O Input/Output units connected to a controller via a
fieldbus.
RLM 01 Redundancy Link Module for PROFIBUS DP. The
RLM 01 connects a non redundant PROFIBUS slave to
the line redundant PROFIBUS.
RS-485 A communication interface standard from EIA
(Electronics Industries Association, USA), operating on
voltages between 0V and +5V. RS-485 is more noise
resistant than RS-232C, handles data transmission over
longer distances, and can drive more receivers
