Configuring CANopen slave devices

Epec (Finland) has released a new version of its system design and configuration tool Multitool. The added features make it easier to configure third-party CANopen slave devices.

Multitool offers a way to design a control system for mobile machines and vehicles. With the release of Multitool 5.2, TPDO messages for the master device are automatically generated according to the slave’s RPDOs that are specified in an EDS file. The customers’ request for an optional feature to reset the RPDO variable values automatically in case of a message timeout has been made possible. In addition, several other improvements have been made for using CANopen slave devices.

Multitool is a system design and configuration tool that helps developers concentrate on functionality while hiding the inherent complexity of programmable devices. It provides easy-to-use interfaces to select preferred programmable control units to the system and create CANopen object dictionaries for these devices. Furthermore, third party CANopen devices, like sensors, can be added to the control system by importing EDS (Electronic Data Sheet) or DCF (Device Configuration File) files from the device manufacturer to the Multitool project. In order to enable system developers to select the best tools for access to the communication system, the system generates CAN databases to export data structures to third party analyzing tools. In this way, the system settings can be re-used in order to analyze, optimize and verify the control system’s performance.
