RW
Denotes read/write access.
SDO
Service Data Object; Used for transmitting non time critical data,
such as parameters.
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.
