1.8 Introduction of DVPCOPM-SL

1. Introduction

DVPCOPM-SL can be used as the master in CANopen network, as well as the slave for other

masters.

As a master, DVPCOPM-SL features:



Complying with CANopen standard protocol DS301v4.02



Supporting NMT Master Service



Error control: Supporting Heartbeat/Node Guarding Protocol



Supporting PDO Service

Max. 200 RxPDOs and 390 bytes of data

Max. 200 TxPDOs and 390 bytes of data

Each slave can be allocated maximum 8 TxPDOs and 8 RxPDOs.



PDO transmission type: Supporting event trigger, time trigger, synchronous cycle, and

synchronous non-cycle



PDO mapping: Every PDO is able to map maximum 32 parameters.

Type of mapping data supported:

Storage space

Data type

1 bit BOOL

8 bits SINT USINT BYTE

16 bits INT UINT WORD

32 bits DINT UDINT REAL DWORD

64 bits LINT ULINT LREAL LWORD



Supporting SDO Service

Number of servers: 0

Number of users: 3



Supporting standard expedited SDO transmission mode



Supporting Auto SDO function.

Able to execute maximum 20 Auto SDOs to each slave



Supporting reading/writing of data in slave by using SDO Service in the ladder diagram in

PLC



Supporting Emergency Protocol:

Able to store 5 latest Emergency messages for each slave

Able to indicate Emergency messages in slave from digital display

Able to read Emergency message through the ladder diagram in PLC



SYNC producer; Range: 0~65,535 ms



As the interface between Delta CANopenBuilder software and CANopen network

The software can configure the network directly through DVPCOPM-SL



In the auto data exchange with a PLC, the user only has to program the D register mapped

in the PLC without applygin FROM/TO instructions. When connected to a PLC,

registers

after D6000 will be adopted temporarily.

As a slave, DVPCOPM-SL features:



Complying with CANopen standard protocol DS301v4.02



Supporting NMT Slave Service



Error control: Supporting Heartbeat Protocol



Supporting PDO Service: Each slave can be allocated maximum 8 TxPDOs and 8 RxPDOs.



PDO transmission type: Supporting event trigger, time trigger, synchronous cycle,

synchronous non-cycle



Supporting SDO Service

Number of servers: 1

Number of users: 0



Supporting standard expedited SDO transmission mode
