Page: 16 / 188

Overview Features of the ME3CAN1-L
1 – 2 MITSUBISHI ELECTRIC
●
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.
