97 FOREWORD

98 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

99 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

100 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

101 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

102 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

103 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

104 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

105 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

106 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

107 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

108 consensus of opinion on the relevant subjects since each technical committee has representation from all

109 interested IEC National Committees.

110 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

111 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

112 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

113 misinterpretation by any end user.

114 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

115 transparently to the maximum extent possible in their national and regional publications. Any divergence between

116 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

117 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

118 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

119 services carried out by independent certification bodies.

120 6) All users should ensure that they have the latest edition of this publication.

121 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

122 members of its technical committees and IEC National Committees for any personal injury, property damage or

123 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

124 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

125 Publications.

126 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publicati ons is

127 indispensable for the correct application of this publication.

128 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

129 rights. IEC shall not be held responsible for identifying any or all such patent rights.

130 International Standard IEC 62386-305 has been prepared by IEC technical committee 34:

131 Lighting. It is an International Standard.
132 The text of this standard is based on the following documents:

156 INTRODUCTION

157 IEC 62386 contains several parts, referred to as series. The IEC 62386 series specifies a bus

158 system for control by digital signals of electronic lighting equipment. The IEC 62386 -1xx series

159 includes the basic specifications. Part 101 contains general requirements for system

160 components, Part 102 extends this information with general requirements for control gear and

161 Part 103 extends it further with general requirements for control devices. Part 104 and Part 105

162 can be applied to control gear or control devices. Part 104 gives requirements for wireless and

163 alternative wired system components. Part 105 describes firmware transfer. Part 150 gives

164 requirements for an auxiliary power supply which can be stand-alone, or built into control gear

165 or control devices.

166 The IEC 62386-2xx series extends the general requirements for control gear with lamp specific

167 extensions (mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear

168 specific features.

169 The IEC 62386-3xx series extends the general requirements for control devices with input

170 device specific extensions describing the instance types as well as some common features that

171 can be combined with multiple instance types.

172 This first edition of IEC 62386-305 is intended to be used in conjunction with IEC 62386­101,

173 and IEC 62386­103. The division into separately published parts provides for ease of future

174 amendments and revisions. Additional requirements will be added as and when a need for them

175 is recognized.
176 The setup of the standards is graphically represented in Figure 1 below.
177
178 Figure 1 - IEC 62386 graphical overview

179 When this part of IEC 62386 refers to any of the clauses of the other parts of the IEC 62386-

180 1xx series, the extent to which such a clause is applicable is specified. The other parts also

181 include additional requirements, as necessary.

182 Where the requirements of any of the clauses of IEC 62386-1XX are referred to in this document

183 by the sentence “The requirements of IEC 62386-1XX, Clause “n” apply”, this sentence is to be

184 interpreted as meaning that all requirements of the clause in question of Part 1XX apply, except

185 any which are clearly inapplicable.

186 The standardization of the control interface for control devices is intended to achieve compatible

187 coexistence and multi-master operation between electronic control gear and lighting control

188 devices, below the level of building management systems. This document describes a method

189 of implementing colour sensors.

249 According to IEC 61347-1 it might be required that the input device has at least supplementary

250 insulation. This depends on the connected components. In this case special attention should

266 9.2 Instance type

267 The instance type (“instanceType”) shall be equal to 5, indicating a colour sensor.

268 9.3 Input signal and value
269 9.3.1 General

270 The “inputValue” shall indicate the value measured by the sensor, encoded as a 24-bit red-

271 green-blue (RGB) value. The red, green and blue components of “inputValue” shall be a strictly

272 monotonic function of the corresponding measured red, green and blue values.

273 After receiver start-up, the sensor may take some time before valid colour measurements are

274 obtained. During this time, QUERY INPUT VALUE and QUERY INPUT VALUE LATCH shall

275 reply as if “inputValue” is MASK. After the first valid colour measurement is obtained, “inputValue”

276 shall not be MASK, except in the case of physical sensor failure (see 9.6.1).

277 The input “resolution” shall be equal to 24.
278 NOTE A “resolution” of 24 implies that “inputValue” is a three-byte value.
279 9.3.2 Input value encoding
280 The “inputValue” shall be encoded shown in Table 1.
281 Table 1 – Input Value encoding
Bit Description Value Alias
0 to 7 Red Observed Red Level [0, 254] “rValue”
8 to 15 Green Observed Green Level [0, 254] “gValue”

283 9.4 Events
284 9.4.1 Priority use
285 9.4.1.1 General
286 The default “eventPriority” is defined in Table 9 .

287 NOTE Application controllers can ensure this instance leaves higher priority timeslots on the bus by setting the

288 instance’s “eventPriority” greater than 2.
289 9.4.1.2 Periodic events

290 The periodic “INPUT NOTIFICATION” message triggered by the report timer that reports the

291 colour value event shall always be sent with priority 5.
292 9.4.2 Bus usage
293 9.4.2.1 Instance level

294 Multiple events from an instance shall not be sent in the same transaction. Also, there is a

295 configurable delay T that shall be taken into account. See 9.5.2 for more information.

296 9.4.2.2 Device level

[9] Unused 0

304 NOTE 1 Due to the 10-bit size of the event message information, the resulting colour report allows only 512 colour

305 combinations and depending on the set-point of the hysteresis, duplicate event messages are possible.

306 NOTE 2 Application controllers can query the “inputValue” to obtain a higher resolution representation of the
