CSA Preface<\/strong><\/p>\n

<\/p>\n

This is the third edition of CSA C900.3, Thermal energy meters \u2014 Part 3: Data exchange and interfaces,<\/em> which is an adoption, with Canadian deviations, of CEN (European Committee for Standardization) Standard EN 1434-3 (third edition, 2015-12) titled Heat meters \u2014 Part 3: Data exchange and interfaces. It supersedes the previous edition published in 2013 as CAN\/CSA-C900.3 (adopted EN 1434-3:2008).<\/p>\n

<\/p>\n

This Standard is one of a group of Standards on Thermal energy meters being adopted by CSA Group, which consists of the following:<\/p>\n

<\/p>\n

a) CSA C900.1 (adopted EN 1434-1) \u2014 Part 1: General requirements;<\/p>\n

<\/p>\n

b) CSA C900.2 (adopted EN 1434-2) \u2014 Part 2: Constructional requirements;<\/p>\n

<\/p>\n

c) CSA C900.3 (adopted EN 1434-3) \u2014 Part 3: Data exchange and interfaces;<\/p>\n

<\/p>\n

d) CSA C900.4 (adopted EN 1434-4) \u2014 Part 4: Pattern approval tests;<\/p>\n

<\/p>\n

e) CSA C900.5 (adopted EN 1434-5) \u2014 Part 5: Initial verification tests; and<\/p>\n

<\/p>\n

f) CSA C900.6 (adopted EN 1434-6) \u2014 Part 6: Installation, commissioning, operational monitoring and maintenance.<\/p>\n

<\/p>\n

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

This European Standard specifies the general requirements and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The meter indicates heat in legal units.<\/p>\n

<\/p>\n

Part 3 specifies the data exchange between a meter and a readout device (POINT \/ POINT communication). For these applications using the optical readout head, the EN 62056-21 protocol is recommended.<\/p>\n

<\/p>\n

For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN 13757-6 (local bus) is recommended.<\/p>\n

<\/p>\n

For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN 13757-2 is necessary to control the M-Bus. For these applications the physical and link layer of EN 13757-2 and the application layer of EN 13757-3 is required.<\/p>\n

<\/p>\n

For wireless meter communications, EN 13757-4 describes several alternatives of walk\/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.<\/p>\n","protected":false},"excerpt":{"rendered":"
