TOPWAY

CAN Interface Reference

1 Basic

CANopen is a CAN-based communication protocol. Over the CANopen master is able to

communicate with up to 127 slaves. CANopen provides SDO objects and PDO objects for

transferring data and data is stored in object dictionary. The object dictionary is like a table that

holds all network accessible data and it may be read and written to by the master.

The Smart LCD is operated as such a slave device and it uses a standard CANopen protocol (CiA

DS301 v4.02). Appendix 1 provides a description of object dictionary. It allows the adjustment of bit

rates from 10 kbit/s to 1000 kbit/s.

2 Message Transmission Format

CANopen message transmission adopts CAN base frame format (11-bit CAN-ID/COB-ID), which

consist of:

 A 11 bit COB-ID, as the unique identifier for message transmission

 Data field, data to be transmitted (0~8 bytes)

11bit

0~8 Byte

Note.

*1. Numerical data type are transferred using little-endian format.

3 Communication Type

Communication type

Descriptions

NMT

NMT is used to switch network state and control nodes, these include NMT node

control, heartbeat, and boot up.

SYNC

SYNC message can be used to synchronize the PDO transmissions.

PDO

PDO is used to transmit real-time data, which does not require a response from the

receiving node.

SDO

SDO is used to transmit data and generates a response for each transmission.

LSS

LSS message is used to configure node-ID and Bit rate.

3.2 NMT

3.2.1 Node Control

Node control is used to switch NMT state. The Node control message has the CAN message

identifier and contains 2 bytes. All CANopen slave nodes must be able to receive this message and

act upon its content.

Message issued by the master:

3.2.2 Heartbeat

Smart LCD device transmits a heartbeat message cyclically within 1017h Heartbeat Producer Time.

When 1017h is set to a non-zero value, the device sending the packet with one byte of data

indicating the NMT status.

Message issued by Smart LCD:

3.2.3 NMT Boot-up

The CANopen Bootup Message is sent by a CANopen device when it starts. This is done to indicate

to host device in the network that it is ready to communicate by other CANopen services.

Message issued by Smart LCD:

0x700 + Node-ID

3.3 SYNC

Message issued by the master:

COB-ID

Data Length

0x80

Note.

*1. SYNC message can be used to synchronize the PDO transmissions.

3.4 PDO

PDOs (Process data objects) are used to transmit real-time data, typically no larger than 8 bytes.

The transfer of PDO is performed with no protocol overhead. PDO communication is based on a

producer/consumer model, and each PDO has a unique identifier. There are two kinds of use for

PDO: data transmission “TPDO” and the data reception “RPDO”.

Smart LCD provides 4 TPDOs and 4 RPDOs, for each PDO the pair of communication and mapping

parameter is mandatory.

3.4.1 PDO communication parameter

The communication parameters indicate the CAN identifier that is used by this PDO, and the

triggering event that prompts the transmission of the related PDO.

The communication parameters for receive PDOs are arranged in the index range from 1400h to

1403h and for transmit PDOs in the range from 1800h to 1803h.

If TPDO’s transmission=0, PDO is transmitted during the next "SYNC" after a value change.

If TPDO’s transmission=1~240, PDO is transmitted for each first to 240th "SYNC" regardless of

value changes

If TPDO’s transmission=254/255 and event time > 5ms, PDO is transmitted when every event time

milliseconds

If RPDO’s transmission=254/255, update the received data directly to the application

3.4.2 PDO mapping parameter

The mapping parameters indicate which information of the local object dictionary is supposed to be

transmitted and where the received information is to be stored. The related mapping entries are

managed in the index ranges 1600h to 1603h and 1A00h to 1A03h.

Description

Sub_index

Object length

Indexes and sub_index determine the location of the mapped object in object dictionary, and the

object length indicates the specific bit length of the object.

Note.

*1. One PDO can map up to 8 objects, and the total bit length of mapping objects is up to 64 bit.

*2. The communication parameter and mapping parameter of TPDO 0 have been defined, it cannot be

changed. It will transmit message containing TPK ID and page ID when touch TPK.

*3. PDO communication can be used only in operational state.

*4. PDO mapping parameters and communication parameters can be configurable via SDO.

3.5 SDO

SDO (Service data objects) enable access to all entries of a CANopen device's object dictionary.

The SDO transmission is initiated by the client and the server replies. As a server of the SDO, if

Smart LCD receives an SDO message, it will reply an SDO response message. The response

message will indicate if the read/write was successful or not, and will provide an abort code if

unsuccessful.

SDO message format:

Data

Smart LCD support different transmission of the SDO :

 Expedited transfer (data length within 4 bytes)

 Normal (segmented) transfer (data length > 4 bytes)

 Block transfer (data length > 4 bytes)

3.5.1 Expedited transfer

Expedited transfer is used to transfer 4 bytes of data or less.
