CANopen DSP 305 Implementation Guide

MAN-CAN305IG (Ver. 1.1)

1-2

LMT

(Layer Management): Functions to inquire and change the settings of

 

certain parameters of the local layers on a CAL module.

LSS

(Layer Setting Services): Functions to inquire and change the settings of

 

certain parameters of the local layers on a CANopen network. An LSS

 

Master can change the following parameters of LSS Slaves:

 

ƒ

Node ID

 

ƒ Timing parameters of the physical layer (Baud Rate)

 

ƒ

LSS address

 

The LSS Slave can be configured for a CANopen network without using

 

any hardware based devices such as DIP-switches.

LSS Master

The device that configures other modules via a CANopen Network.

 

There may be only one LSS Master in a network.

LSS Slave

The device that is configured by the LSS Master via a CANopen Network

 

is called the LSS Slave.

MAC

(Medium Access Control): One of the sub-layers of the Data Link Layer

 

in the CAN Reference Model that controls who gets access to the

 

medium to send a message.

NMT

(Network Management): One of the service elements of the application

 

layer in the CAN Reference Model. The NMT serves to configure,

 

initialize, and handle errors in a CAN network.

1.3LSS Hardware Restrictions (LSS Address)

All LSS Slaves must support valid Object Dictionary entries for Identity object [1018h] which has 32 bits for each part of the LSS Address:

ƒ

Vendor-ID

(numerical number)

ƒ

Product-Code

(numerical number)

ƒ

Revision-Number

(major an minor revision as numerical number)

ƒ

Serial-Number

(numerical number)

AProduct-Code, Revision-Number and a Serial-Number are assigned by the device supplier. The LSS address which must be absolutely unique. No other LSS slave may have the same LSS address.

1.4LSS Operating Restrictions

To function properly the following restrictions apply:

ƒAll devices on a CANopen network must support LSS.

ƒThere can be only one LSS Master.

ƒAll nodes are required to start-up with the same initial baud rate.

ƒLSS communication can take place during any NMT state such as “stopped” or "pre-operational".
