EN 13757-4 PDF
Wireless M-Bus or Wireless Meter-Bus is the European standard (EN ) that specifies the communication between utility meters and data loggers. The Wireless M Bus specification EN defines six different . Mode N: preamble length is configurable (value required by EN is 2 bytes). This document (EN ) has been prepared by Technical Committee CEN/TC “Communication systems for meters”, the secretariat of which is.

Again, this is a bi-directional version of C1. A total of three different data rates are specified along with one way or two way communication.
Take the smart route to manage medical device compliance. The faster, easier way to work with standards.
The Wireless M-Bus standard was first published in and has since been improved based on feedback from several thousands of field installations in very harsh environments — after all, many water and gas meters are located below ground level, in remote basements, sheds, or culverts. Send data a few times per 13775-4. Search Knowledgebase Ask A Question?
T1 Unidirectional This is the Frequent T ransmit mode and metering devices periodically send data to collectors that are in range. It includes a variety of proposals for relaying data frames as a means of overcoming issues related to range between the meter and the data collection points.
This is Wireless M-Bus Wireless M-Bus is designed to be a robust, power efficient, long range wireless communication solution that operates in the license-free ISM bands. The Wireless Meter Bus or Wireless M-Bus is aimed at remote reading of gas or electricity meters as well as any other types of meters that may need to be read remotely. Using Wirelss M-Bus for your network can be a simple task, or a complex mission, depending on what features you intend to use. This is known as the C ompact mode.

Worldwide Standards We can source 133757-4 standard from anywhere in the world. Again this is a bi-directional version of the T1 mode.
The relative simplicity of the stack makes it very energy and code efficient. Communication modes There are different requirements for differing applications for WM Bus. Search all products by. The Wireless M-Bus has several options that may be chosen for the radio parameters. There are different requirements for differing applications for WM Bus. EN is a very flexible and open specification, where some parts are not described em detail or left for future implementation.
