Software stacks from RT-Labs achieve industry stamp of approval

Class B compliance leads to greater assurance when designing Profinet and IO-Link-enabled devices.

RT-Labs, the leading software engineering specialist in embedded industrial communications, has confirmed that its Profinet device stack is now fully class B compliant. This is the highest attainable class without requiring investment into additional application-specific integrated circuits (ASICs) or other hardware. The feature-rich C-based stack has a small footprint that facilitates its integration. It also offers ease of use and reliability, making it a more attractive alternative to complex Profinet stacks available from other vendors. Because of these attributes, the stack is highly optimised for use in resource-constrained embedded systems.

The company has also announced that its IO-Link master stack has achieved the manufacturer's declaration of master protocol conformity from TEConcept, following extensive IO testing. As a result, the stack has proved that it can be deployed in IO-Link installations for fieldbus industrial networking purposes. Like its Profinet device stack, RT-Labs' IO-Link master stack is well suited to embedded applications, including those that require as low as 80kB Flash and 20kB RAM. It has numerous diagnostic functions incorporated to support long-term operational integrity. For it to be more accessible to the engineering community, this stack has recently been made publicly available via the RT-Labs GitHub repository.

"IO-Link is a modern way of interfacing with smart sensors in industrial applications, and we are seeing a great increase in demand from our customer base, across a broad variety of different market segments,” states Olof Lennerstedt, CEO RT-Labs “Through this new declaration of conformity, customers can specify our stack relating to IO-Link with even more confidence, which will drive further uptake... “Likewise, class B compliance of our Profinet device stack is certain to result in its more widespread deployment.”
