Overview
● Network management (NMT)
– General NMT services
– Boot-up Message
– Node guarding Master/Slave
– Heartbeat Consumer/Producer
CANopen€ services according to CiA€-302 V4.1
● NMT master
The network management provides services for controlling the network behavior of CANopen€
devices as defined in CiA€-301 and CiA€-302. All CANopen€ devices of a network referred to as
NMT slaves are controlled by services provided by an NMT master.
● Flying master
The flying master mechanism provides services for a hot stand-by NMT master within a CANopen€
network.
● Configuration manager
The Configuration manager provides mechanisms for configuration of CANopen€ devices in a
CANopen€ network.
● SYNC producer
The SYNC producer broadcasts the SYNC object. The SYNC service provides the basic network
synchronization mechanism.
Layer Setting Services master (LSS) according to the Standard CiA€-305 V2.2
It is necessary to set the baud rate and node number of the CANopen€ devices. But some CANopen€
devices, e.g. devices with high IP protection like rotary encoders, waterproof sensor, etc. don't have
DIP-switches for these setting. Such devices must be configured by CAN using this LSS.
CANopen€ device profiles according to CiA€-405 V2.0
Interface and Device Profile CiA€-405 V2.0 for IEC 61131-3 Programmable Devices allows communi-
cation with other Device Profiles (e.g. encoder CiA€-406, motion/ drives CiA€-402, etc.).
Setting back up in non-volatile memory
The following setting values will be backed up in the Flash-ROM:
– Setting values stored in the buffer memory;
– Module configuration stored in the Object Dictionary;
– Setting values of Concise Device Setting File (CDCF).
CAN layer 2 communication
Besides the CANopen€ mode, the ME3CAN1-L can be switched to CAN layer 2 communication mode,
and be set up so that it can be used for the customer's own CAN based communication protocol.
