Introduction
1 Introduction
The Rotork Profibus DP Actuator Control option card (PFU)
conforms to the PNO as compliant with specifications
IEC61158 and EN50170. The card supports both Profibus
DP-V0 cyclic and Profibus DP-V1 acyclic messages. Three
versions are available - single channel, simple dual channel
and RedCom dual channel. The simple dual channel card
does not include the Redstate diagnostics whilst the RedCom
dual channel card fully supports RedCom (Redundant
Communication) extensions to the V1 protocol as specified
by PNO for systems using either FR (Flying redundancy) or SR
(System redundancy) configurations. The inclusion of acyclic
message capability (V1) allows for system maintenance and
asset management tools to be used. Electronic data sheets
are available in GSD, EDD and DTM formats.
•
Profibus DP-V0 and DP-V1 compliant
•
RedCom redundancy included, both FR and SR modes
•
GSD, EDD, DTM device description files available
•
Address changes by master class 2, IR/Bluetooth
®
,
FDT or PDM
•
Zero internal stub length
•
Mounted within an IP68 enclosure, 8 meters for 96 hours.
•
All card settings are non-intrusive and can be made over
the data highway or with Bluetooth or the setting tool.
The Profibus DP Module circuits do not impinge on the
actuator control electronics; the actuator itself remains fully
self-protecting. The module performs the tasks of network
interface, actuator data collection and the issuing of actuator
commands to open, stop, close, perform an ESD operation or
move to a set position.
