Delta Electronics DVPCOPM-SL Connecting to CANopen Connection Port, Constructing CANopen Network

CANopen Communication Module DVPCOPM-SL

3.3Connecting to CANopen Connection Port

zPlease wire following the PIN definition of the connection port.

zThere 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.

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

4 Constructing CANopen Network

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.
