Introduction of Ethernet-CANopen slave converter_GCAN

1. Introduction

1.1 Overview

The GCAN-302 is a CANopen slave and Ethernet converter. The CAN side of the GCAN-302 integrates the CANopen slave protocol. The GCAN-302 converts the CANopen slave protocol signal to the Ethernet signal or converts the Ethernet signal to the CANopen slave protocol signal. With this converter, devices using the CANopen master protocol can connect to Ethernet without changing the hardware architecture and extending the range of CAN bus applications.

Note: CAN-302 is required to be customized.

Compatible with SOCKET work (TCP Server, TCP Client, UDP, etc.), the host computer communication software follows the standard SOCKET rules

2. Installation

2.1 Installation and fixation

GCAN-302 can be installed on a DIN rail, as shown in figure 2.1.

Only CAN_H and CAN_H connect with each other, then CAN_L and CAN_L connect with each other. Then we establish a connection.

Figure 2.1 GCAN-302 module installation

Note: DIN rails require to connect with ground wire.

GCAN-302 power interface definitions are shown in table 2.1.

2.2 Connect to PC

Connect the converter to computer with a network cable. Then GCAN-302 LAN interface can establish communication.

2.3 Connect to CANopen

The pin definitions for the CAN side of GCAN-302 are shown in table 2.3.

 

Only CAN_H and CAN_H connect with each other, then CAN_L and CAN_L connect with each other. Then we establish a connection.
