POWERLINK Stack and Protocol Workshop


Understanding the modern Real-Time Ethernet based fieldbus, connecting and starting up devices.

Providers of devices for automation technology face the challenge of making their products suitable for several network protocols at the same time in order to take advantage of the full market potential. The netX platform provides the flexible hardware, for which Hilscher offers almost all traditional fieldbus as well as modern Real-Time Ethernet protocol stacks. Every protocol has specific functions and mechanisms, which the user as the implementer must understand.

The fundamentals of the POWERLINK standard are first taught in this training session. The main part of the workshop will then focus on the Hilscher protocol stack. Features, functions and the interface to the user application will be discussed. A POWERLINK Controlled Node will be started up in practical exercises. The training is suited both for users who use the LFW model - loadable firmware with the netX as a companion chip, and also for those who use the LOM model - linkable object modules with the user application on the netX Chip.

The practical exercises are carried out with a Hilscher evaluation board and the corresponding Hilscher protocol stack.


1 day, from 9:00 am to 5:00 pm
