Abstract

Convergent communication networks with a multitude of differing data flows are a promising approach to increase information consistency and device interoperability and so enable new applications and business models in industrial automation and production environments. A required key feature for the application of control applications is deterministic real-time behavior of such networks. With the presence of IEEE 802.1 TSN, there is a promising vendor and application independent networking technology available. This paper analyzes typical parameters and requirements of fieldbus technology which is used today for real-time applications and their relation to TSN mechanisms within convergent networks. Also, the potential of future realizations using TSN in conjunction with OPC UA Pub/Sub is shown. Focus is laid on specific challenges which will require some further work to enable fieldbus-like performance over such infrastructures.
