CANopen Function and Operation
7.1 The Introduction of CANopen
It supports the PDO (process data object) service.
It supports the SDO (service data object) service.
It supports the service of reading the emergency from a slave.
It supports the PDO (process data object) service.
It supports the service of reading the emergency from a slave.
7.2 The Installation and the Network Topology
Page
Page
Page
7.3 The CANopen Protocol
The PDO provides the direct visit channel for the device application object, is used to
There are two kinds of uses for PDOs. The first is data transmission and the second data
+-+-
The PDO is described by means of the producer/consumer mode. The data is transmitted
Every PDO is described by two objects in the object dictionary: The PDO communication
The PDO transmission mode: synchronous and asynchronous
The SDO is used to build the client/server relation between two CANopen devices. The
The SDO message contains the index information and the subindex information which can
The SDO can transmit the data in any length. If the data length is more than 4 bytes, the
The structures of the SDO requested message and reply message are as follows.

7.4 Sending SDO, NMT and Reading Emergency Message through the Ladder Diagram
The data format of the SDO request message:
Size: The length of the message data. The counting starts from D6253 with byte as the unit.
Node ID: The node address of the target equipment on CANopen network.
The data format of the SDO response message:
Status code:
Type: In SDO response message, 43 (Hex) refers to reading 4 bytes of data; 4B (Hex) refers
The data format of the NMT request message:
When status code is 1, it indicates that NMT operation succeeds. When status code is not
Node ID: The node address of the target equipment on CANopen network. NMT service code:
The data format of the NMT Response message:
Node ID: The node address of the target equipment on CANopen network.
The data format of the Emergency request message:
Node ID: The node address of the target equipment on CANopen network.
The data format of the Emergency response message:
Number of data stored: The latest number of Emergency messages CANopen master
The data in D6004-D6007 are the content of Emergency 1 and every Emergency message

7.5.1 Description of Indicators
7.5.2 CANopen Netw ork Node State Display
As a master, DVP-ES2-C supports maximum 16 slaves ranging from node 1 to node 16.
While the special auxiliary relay M1349 of DVP-ES2-C is ON, the CANopen function is
The error code of every node is displayed through the corresponding special register and the

Program control: D6282 is given the value K256 through WPL software. That is, the speed
When M0 turns from OFF to ON, write K256 to D6282 and then the value is written to P1-09
When M1 turns from OFF to ON, turn P2-12 on and call the speed specified by parameter
When M1 turns from ON to OFF, the speed command becomes 0 and the motor stops
