6.4 CANopen over Ethernet

The Ethernet POWERLINK Standardisation Group (EPSG) is working closely with
the   CiA   (CAN   in   Automation)   organisation   to   integrate   CANopen   with
POWERLINK.   CANopen   standards   define   widely   deployed   communication
profiles, device profiles and application profiles. These profiles are in use millions
of times all over the world. Integration of POWERLINK with CANopen combines
profiles, high performance data exchange and open transparent communication
with TCP/UDP/IP protocols.
The   POWERLINK   communication   and   device   profiles   implemented   in   the
encoder are based on CANopen communication profile DS301 and device profile
DS406.

6.5 POWERLINK nodes

The node managing the permission to send messages to the Ethernet is called
the POWERLINK Managing Node (MN).
All other nodes transmit only within communication slots assigned by the MN.
They are thus called Controlled Nodes (CN).

6.5.1 POWERLINK Managing Node (MN)

Only the MN is allowed to send messages independently – i.e. not as a response
to   a   received   message.   Controlled   Nodes   are   only   allowed   to   send   when
requested to by the MN.
The Controlled Nodes are accessed cyclically by the MN. Unicast data are sent
from the MN to each configured CN (frame: PReq), which then publishes its
data via multicast to all other nodes (frame: PRes).
All available nodes in the network are configured on the MN.
Only one active MN is permitted in a POWERLINK network.

6.5.2 POWERLINK Controlled Node CN)

CNs are passive bus nodes. They only send when requested by the MN.
The   ability   of   a   node   to   perform   CN   functions   is   indicated   by   the   device
description entry 

D_DLL_FeatureCN_BOOL

.

Lika encoders are CN devices and  comply with the “EPSG Draft Standard 301
Ethernet   POWERLINK   Communication   Profile   Specification  Version   1.2.0”.   as
well   as   with   the  CANopen   Profiles   “DS301   CANopen   Application   Layer   and
Communication Profile” and “DS406 Device Profile for Encoders” according to
the POWERLINK specifications.

6.6 POWERLINK Basic Frame

The POWERLINK Basic Frame format contains 5 fields:

•

Reserved (1 bit)

•

MessageType (7 bits)

•

Destination node address (1 byte)

•

Source node address (1 byte)
