ABB FEPL-02 Ethernet POWERLINK User Manual

18 About the manual
MN Managing Node; A node capable of managing
the SCNM mechanism in a POWERLINK
network.
Object Dictionary A local storage of all communication objects
recognized by the device.
OSI Open Systems Interconnection.
PDO Process Data Object; Used for transmitting time
critical data, such as control commands,
references and actual values.
PReq PollRequest; A frame used in the isochronous
phase of the cyclic communication. With
PollRequest, the MN requests the CN to send
its data.
PRes PollResponse; A frame used in the isochronous
phase of the cyclic communication. The CN
responses with a PollResponse frame when it
receives a PollRequest from the MN.
R Read-only access.
RW Read-write access.
SCNM Slot Communication Network Management; In a
POWERLINK network, the MN allocates data
transfer time for data from each node in a cyclic
manner within a guaranteed cycle time. Within
each cycle there are slots for Isochronous Data,
and for Asynchronous Data for ad-hoc
communication.
The SCNM mechanism ensures that there are
no collisions during physical network access in
any of the networked nodes. Thus, it provides
deterministic communication via Legacy
Ethernet.
SDO Service Data Object; Used for transmitting non
time critical data, such as parameters.
