Though users have to keep in mind that those aspects, strictly fixed in IEC LE, may change as time goes by.
Any manufacturer could go on implementing products with specific solutions in aforementioned aspects. This document strictly defined those aspects where and parts allowed flexibility data model, data sets, 6185-9 and transmission rates, etc.
These and several other questions in relation to IEC are addressed in this paper. When IEC 61805-9 devices will be available on the market? This is the main difference between and LE. When one is creating a standard, one of the main goals is to provide time invariance of standardized aspects.
What’s new Press Releases. Its common to address this communication model in terms of a protocol: One of the communication models defined is transmission of sampled value data described in part This is also the case with IEC From to he was a Research Assistant with the Institute of Sensor and Actuator Systems, VUT, conducting research in the field of miniaturized sensor technology. Or will we face a battle of profiles? From to he worked as Hardware Test Engineer and Hardware Developer for major companies active in the automotive industry.
In the following years he worked as development engineer and product manager for major companies in the digital broadcast industry.
Though nobody cancels backward compatibility postulate. But this also led to the situation when there have been no commercial products available on the market.
This could led to interoperability issues and to the whole range of IEC products at the end customer facilities with different specifics. Get support Contact form Offices and Partners. To be time-invariant descriptions 6850-9 are as general as they can be, describing control block structure and parameters to be transmitted in an abstract way.
What is the difference between IEC and IEC LE? | Digital Substation
Will simplicity supersede complexity? But what does this mean for the planning of future substation environments? For example, new time synchronization methods, sampling rates and etc.
Based on the current implementation situation and the findings from the IEC lec plugfestthe paper explores the differences and commonalities of the two PTP profiles for power applications and their interoperability.
During his time as hardware developer he was intensively engaged with time synchronizing technologies for digital TV and radio transmitters in single frequency networks.
IEC Will simplicity supersede complexity? Though describes mapping on the specific communication protocol, there is still no ice of data model to be implemented, data sets, sampling and transmission rates, time synchronization methods to be used.
This is not a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc. This is done not to restrict any possible practical implementations.
