Connecting to CANopen Connection Port 

z  Please wire following the PIN definition of the connection port. 

z  There are two communication interfaces on DVP-SV to communicate with the PC. COM1 is the 

standard RS-232 interface, and COM2 RS-485. Both interfaces comply with Modbus protocol. The PC 

communicates directly to PLC through COM1. 

z  We recommend you also apply Delta’s power module in the connection.

In this section, we will introduce how to construct a complete CANopen network by using DVPCOPM-SL and 

other slaves. 

Before constructing a network, you have to first know clearly what the network is for and start a preliminary 

planning for the data to be exchanged. The plan shall include the slaves to be used, type of transmiaaion and 

the data to be exchanged, total length of data to be exchanged, requirement on the response time for data 

exchange, and so on. These information will decide whether the network you construct is a reasonable one, or if 

it satisfies your needs, and even affect the later-on network sustainability and flexibility of network capacity 

upgrade. 

In the example below, we will illustrate how to control RUN/STOP and speed of a Delta ASD-B servo drive by 

a Delta digital I/O module DVP-08ST.
