What is BS EN 50325-1 ‒ Controller-device interfaces about?
BS EN 50325-1 is the first part of an international multi-series standard that covers industrial communications subsystem for controller-device interfaces.
BS EN 50325-1 applies to controller-device interfaces that provide, defined interfaces between low-voltage switchgear, control gear, control circuit devices, switching elements, and controlling devices.
BS EN 50325-1 specifies requirements for controllers and devices utilizing these interfaces, including not only the communication protocol specification, but also associated relevant electrical and mechanical characteristics.
BS EN 50325-1 establishes a consistent terminology and format for the subsequent interfaces. It also harmonizes requirements of a general nature, in order to reduce the need for testing to different standards, increase understanding and facilitate comparisons of controller-device interface standards.
Note: The controller-device interface standards currently part of this series are:
- EN 50325-4: CANopen
- EN 50325-5: Functional safety communication based on EN 50325-4
Who is BS EN 50325-1‒ Controller-device interfaces for?
BS EN 50325-1 on Controller-device interfaces is useful for:
- Internet of Things IoT applications
- Simulators assembly
- Supervisory control and data system
- Wireless communication systems
- Data sensors and interface applications
Why should you use BS EN 50325-1‒ Controller-device interfaces?
The CAN protocol was originally developed by Robert Bosch GmbH for the European automotive market for replacing expensive, wire harnesses with low-cost network cable on vehicles. As a result, the CAN protocol has a fast response and high reliability, and the protocol has been standardized as ISO 11898. The interfaces described in the standard, are based on a broadcast-oriented communications protocol - Controller Area Network (CAN).
The controller-device interfaces described in BS EN 50325-1 utilize a common base protocol to provide solutions to users in industrial environments who have a need for simple communications and diagnostics. The application layer of each network has been created to meet specific performance and market requirements.
BS EN 50325-1 serves the objective to give an interface user, to acquire gain in productivity that may be realized through reduced wiring, reduced start-up time, improved quality of output, and downtime time. The interfaces described inhere provide you with low-cost connectivity between low-voltage switchgear, control gear, control circuit devices, switching elements, and control devices and eliminate expensive hardwiring.
The solutions described in BS EN 50325-1 can be useful to industries users to solve application requirements involving low-voltage switchgear and control gear. They are characterized by:
- Their ability to power connected devices directly from the network
- Their ability to operate in harsh environments typified by those encountered at the machine level by controls in industrial applications
- Usage of the sophisticated medium access rules of CAN which allows both organizations of traffic based on user-assigned priorities and efficient resolution of occasional access conflict
- A wide range of exchange services allowing precise tailoring of data exchange to the actual application needs as well as simultaneous distribution of data to a selected set of connected devices
- Their capability to simultaneously support data acquisition, diagnostics, messaging, and programming/configuration as required, amongst others, for systems interfacing controllers to low voltage switchgear and control gear in industrial applications
