By default, a DataWriter of an unbounded type won’t be able to communicate with a DataReader of a bounded type. DDS includes the max size of a bounded type as part of the data type information (known as TypeCode or TypeObject). Since the data type information is used during the Discovery phase, if ...

There are a some restrictions to take into account when integrating RTI Database Integration Service (DIS) and RTI DDS Toolkit for LabVIEW together. These are the following: The database limitations, see Appendix B on DIS User's Manual. National Instrument (NI) Cluster types are mapped to IDL types ...

Note: Applies to RTI DDS Toolkit for LabVIEW version 3.1.1 or later The best way to understand the licensing methods of the RTI DDS Toolkit for LabVIEW is to separate them per platform: Windows and NI Linux. Licensing in Windows When you download the RTI DDS Toolkit for LabVIEW (from the VI Package ...

This solution is only a workaround until the Request/Reply API is available in LabVIEW. This will only work for one Requester and one Replier. The Request/Reply communication pattern is pretty useful for industrial applications. It is quite normal to have an application requesting an action to ...

A normal scenario in RTI Connext DDS is to have a Publisher that generates samples and several Subscribers that receive the generated data. In other words, the expected out-of-the-box behavior is for all Subscribers to get all the data. This is so because each Subscriber has its own DataReader for ...

This error is typically due to array management. Working with LabVIEW arrays and sending them through RTI Connext DDS can be tricky. Here you have some guidelines on how to fix this error For versions of the RTI DDS Toolkit previous to 1.2.0.90 In LabVIEW, arrays are declared with an initial length ...

QoS profiles provide a way to configure your DDS application, defining most aspects of the DDS paradigm and the underlying communication mechanisms. As part of RTI DDS Toolkit for LabVIEW we provide a set of pre-defined QoS profiles. These profiles solve general use cases such as a Reliable ...
