CanOpenOpcUa NG

Introduction

The CanOpenOpcUa NG Server is based on a platform-independent service-oriented unified architecture from Opc Foundation based on the Quasar framework. It can be used as a software interface between a SCADA system (WinCC OA) and hardware devices connected via CAN bus and using the CANopen protocol for the device communication.

Versions

XML Configuration File

For the server to manage the communication and flow of data between the master and nodes, a configuration XML file has to be provided detailing info about CAN buses and each of the nodes. Documentation of how a config file is organized can be found in the attachments of this Twiki, although it is also found in /opt/CanOpenOpcUa/doc once the RPM is installed.

Dependencies

• The basic version Linux is Almalinux 9.3.
• All needed RPMs can be found below:
  • systec_can-1.0.6.al9_3.18.rpm - systec driver
  • libsocketcan-devel-0.0.12-0.1.al9.rpm - socket can library
• Consider installing UaExpert for AlmaLinux 9, it is a very useful OPC UA client.
