What is BS EN 62026-3 - Controller-device interfaces (CDIs) - DeviceNet about?
BS EN 62026-3 is the third part of the multiple series standard that specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable – one of these pairs provides a differential communication medium and the other pair provides power to the devices.
BS EN 62026-3 establishes requirements for the interoperability of components with such interfaces.
Note: BS EN 62026-3 requirements apply in addition to the general requirements of IEC 62026-1.
Who is BS EN 62026-3 - Controller-device interfaces (CDIs) - DeviceNet for?
BS EN 62026-3 on controller-device interfaces is useful for:
- Manufacturers and suppliers of interface controllers
- IT automation industries
- Dealers and distributors of interface controllers
- Designers and developers of interface controllers
- Test/ service providers interface controllers
Why should you use BS EN 62026-3 - Controller-device interfaces (CDIs) - DeviceNet?
BS EN 62026-3 classifies DeviceNet uses into two conductor pairs within one cable – one of these pairs provides a differential communication medium, and the other pair provides power to the devices. Also, DeviceNet connections are used to provide logical paths between multiple applications. DeviceNet supports the transmission of I/O data, diagnostics, messaging and programming/configuration. Data exchange is event-driven (change of state), cyclic, polled, strobed, or multicast polled.
Therefore, BS EN 62026-3 specifies:
- Requirements for interfaces between controllers and switching elements
- Normal service conditions for devices
- Constructional and performance requirements
- Tests to verify conformance to requirements
Overall, BS EN 62026-3 specifies DeviceNet interfaces controlling devices to control circuit devices or switching elements.
