CANopen Communication Module DVPCOPM-SL
Warning
Please read this instruction carefully before use and follow this instruction to operate the device in order to prevent
damages on the device or injuries to staff.
Switch off the power before wiring.
DVPCOPM-SL is an OPEN TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the
device (e.g. key or specific tools are required for operating the enclosure) in case danger and damage on the
device may occur.
DVPCOPM-SL is to be used for controlling the operating machine and equipment. In order not to damage it, only
qualified professional staff familiar with the structure and operation of DVPCOPM-SL can install, operate, wire
and maintain it.
DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check
all the wirings again before switching on the power and DO NOT touch any terminal when the power is switched
on. Make sure the ground terminal is correctly grounded in order to prevent electromagnetic interference.

1Introduction
1. To ensure correct installation and operation of DVPCOPM-SL, please read this chapter carefully before using your
DVPCOPM-SL.
2. This chapter only provides introductory information on DVPCOPM-SL. For more detailed information on CANopen
protocol, please refer to relevant references or literatures.
3. DVPCOPM-SL is a CANopen module operating on the left side of PLC CPU. PLC CPU can have maximum 8
DVPCOPM-SL modules connected to its left side. DVPCOPM-SL master module is responsible for the data
exchange between PLC and other slaves on the bus when PLC CPU is connected to the CANopen network via
DVPCOPM-SL. To achieve data exchange, DVPCOPM-SL master module is used for transmitting the data in PLC
to slaves on the bus and meanwhile returns the data in slaves to PLC.
4. PLC connected to the right side of DVPCOPM-SL includes DVP-SV, DVP-SX2, DVP-SA2, DVP10MC11T,
DVP-EH3-L, and DVP-EH2-L.

2.4 CAN Network Endpoint and Topology Structure
In order to make the CAN communication more stable, the two endpoints of the CAN network are connected to 120
ohm terminal resistors. The topology structure of the CAN network is illustrated below.
2.5 Address Switch
The switch is used on setting up the node address of DVPCOPM-SLon CANopen network. Range: 1 ~ 7F (0, 88 ~ FF
are forbidden).
Switch setting Content
1 ~ 7F Valid CANopen node address
0, 80 ~ FF Invalid CANopen node address

Example: If you need to set the node address of DVPCOPM-SL to 26 (1AH), simply switch the corresponding switch of
x161to 1 and the corresponding switch of x160to A.
Note:
Use slotted screwdriver to rotate the switch carefully in case you scratch the switch.
Please set up the node address when the power is switched off.After the setup is completed, re-poser
DVPCOPM-SL.

2.6 Function Switch
The switch is used on setting up the baud rate between DVPCOPM-SL and CANopen network (DR0 ~ DR2). See the
table below for the baud rate and its maximum communication distance.

Note:
If the firmware of DVPCOPM-SL is under V1.32, IN0 is invalid. But the function of IN0 is as below for the firmware of
V1.32 and above.
When IN0=ON and the master and slave make the connection, the master sends the NMT message (0x82 or 0x80)
first and then the SDO message. The interval time is 100ms between the two messages. The timeout for SDO
sending is 100ms.
When IN0=OFF and the master and slave make the connection, the master sends the NMT message (0x82 or
0x80) first and then the SDO message. The interval time is 1s between the two messages. The timeout for SDO
sending is 1s.
2.7 Digital Indicator
The digital indicator provides the following two functions:
Displaying the node address of DVPCOPM-SL.
Displaying the error message of slave.
