Learn more about your already-purchased middleware features and hear Twin Oaks Computing's plan for future CoreDX DDS development.

When you are busy with software development milestones, integration and testing activities, finding ad fixing bugs, demonstrations and product launches... it's easy to ignore your middleware. As long as it's working, it's easy to keep using it as you've been using it, and not actively pursue new features and functionality. Join Twin Oaks Computing to learn more about your already-purchased middleware features and to hear Twin Oaks Computing's plan for future CoreDX DDS development.

In a session developed exclusively for CoreDX DDS customers, this webinar provides an overview of the CoreDX DDS features set - with a focus on newly released and upcoming capabilities.

Target audience: This webinar targets technical audiences with CoreDX DDS experience who would like to take advantage of additional functions and features, or plan for future development with CoreDX DDS.

CoreDX DDS Tips & Tricks

Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

Do you use return_loan() appropriately?

A common issue for new DDS developers is deciding when to use the return_loan() API. Here's some clarification:

return_loan() should be paired with *any* successful call to any read() or take() variant. Even if there is no 'valid_data' returned from these functions, if the return value from read() or take() (or any of their variants) is RETCODE_OK, you must call return_loan().

Common consequences of not calling return_loan()

  • Increasing memory usage as the reader cache grows
  • the same samples (or unexpected number of samples) returned in subsequent read() or take() calls

CoreDX DDS Tips & Tricks are intended to be useful for engineering using CoreDX DDS. If you have any questions, please contact us here.

Security with CoreDX DDS: Protecting Your Network from Attacks - Upcoming Webinar

April 6, 2022 - 10am MST

Register Here

Industrial systems across all industries are connecting devices and components that have historically not been connected. Adding connectivity created enormous opportunity from telematics and predictive maintenance to more intelligent operations. However, adding connectivity adds exposure to network based attacks. These industrial systems share common connection requirements for reliability, scalability, and now, security. How are your software components connected? Do your connectivity protocols meet your reliability, scalability, and security requirements?

This presentation takes and in-depth look at Industrial Internet of Things (IIoT) applications using CoreDX DDS, an implementation of the Data Distribution Service (DDS) standardized connectivity protocol from the Object Management Group (OMG), with a focus on secure data communications. CoreDX DDS is a proven, mature protocol, with over 15 years of implementation history across military, industrial, medical, power, automotive, and IIoT industries. CoreDX DDS Secure includes state of the art technologies for end-to-end secure data communications.

Attendees will learn:

  • Methods for securing connected devices
  • Benefits and risks associated with connected systems
  • Benefits of using standardized middleware to connect systems
  • Features of CoreDX DDS and the Data Distribution Service DDS standards

Who should attend:

  • Solutions Architects developing connected industrial devices and systems
  • Software and Systems Engineers building sophisticated distributed systems
  • Device Manufacturers concerned with keeping connected devices secure
