CAN in Automation organizes plugfests as a service for CiA members. The purpose of these events is to check and improve the interoperability of CANopen devices. It helps device designers to optimize their device software. In addition, system designers may get a better understanding of the problems occurring during device integration. They also learn about the latest CANopen implementations, products and services in this specific application field. The plugfest participants connect directly with key experts and technology specialists from the CiA CANopen community, who have long-term experience in certain CANopen application fields, and thus can test and improve their implementations. The participants discuss interoperability issues with other CiA community members and gain information from interoperability tests to improve application software and equipment firmware.

Additionally, they share their experiences with other CiA CANopen community members with regard to the functionality and interoperability of CANopen application end devices and control systems. Participants also reinforce the collaboration on interoperability and build even stronger communication bonds between members of the CANopen community. Last but not least, the results of plugfests are a valuable input for improving the related CANopen profile.
