FOREWORD

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

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

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

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

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

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

interested IEC National Committees.

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

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

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

misinterpretation by any end user.

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

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

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

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

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

services carried out by independent certification bodies.

INTRODUCTION

The development of smart sensors which integrate analog-to-digital conversion and digital

processing of the captured sensor signal(s) is in progress. A smart sensing unit, which

comprises a smart sensor; a terminal module, to control the smart sensor and perform

wireless communication; and a power supply for the smart sensor and the terminal module,

can send the output data of the smart sensor wirelessly to the outside. Here, the power supply

can be a plug-in power supply, a battery, an energy harvester, or their combination. A smart

sensing network where a large number of smart sensing units are located in manufacturing

factories, offices, and stores has been examined. With this network, environmental

monitoring, sensing of operational situations of manufacturing equipment and sensing of other

various events contribute to the realization of the following outcomes by analyzing the

collected sensing data. Namely, energy saving, improvement in factory productivity such as

operation rate, shortening of production lead time, preventive equipment maintenance, and

product quality improvement can be achieved.

However, considering the three components of the smart sensing unit, namely, the smart

sensor, terminal module, and power supply, standardization regarding control schemes to

connect the components to each other and regarding the indication of specifications of the

components has not been sufficiently established yet. This issue leads to the present situation,

where the development of each component in the smart sensing unit has not proceeded

efficiently.

The IEC 60747-19 series aims to address this issue. The IEC 60747-19 series comprises two

parts and its structure is currently conceived as follows:
Part 19-1: Smart sensors – Control scheme of smart sensors

Part 19-2 : Smart sensors – Indication of specifications of smart sensors and power supplies

to drive smart sensors

Part 19-1 specifies a control scheme of the smart sensor from the terminal module in the

smart sensing unit. Generally, the manufacturers of sensors have incorporated into the

sensors various parameters and conditions for sensing operations to fulfil various requests

and needs of the users. Therefore, it has been quite difficult for the users to understand how

to set the parameters and conditions adequately and master the use of sensors. This issue

has been a considerable obstacle in designing the smart sensing unit and smart sensing

system. The main objective of this part is to solve this obstacle for future expansion of the

smart sensors and smart sensing network systems.

Part 19-2 aims to provide guidelines to specify information that is required when the smart

sensing unit is newly designed. When the smart sensing unit is newly designed especially to

use an autonomous power supply, the designers have to appropriately arrange the selection

of the components of the unit and their usage conditions to satisfy that the power capability of

the power supply successfully exceeds the total power budget to be consumed in the unit as a

whole. First, information about the detailed power consumption characteristics of the smart

sensors is indispensable for this achievement. Namely, information about time-axis power

profiles which is not necessarily described in the datasheet of sensors is essential when

intermittent sensing operations are often adopted and a careful lower power design including

time-axis characteristics to allow adoption of an autonomous power supply is needed in IoT

(Internet of Things) applications. Therefore, Part 19-2 discusses an indication of smart

sensors’ electrical characteristics of time-axis power profiles. Second, information about total

power capability of the power supply to drive the unit and the smart sensor(s) is essential.

This power supply as a module comprises (a) primary battery(batteries), and(or) (a)

secondary battery(batteries), and(or) (an) energy harvester(s), or their combinations.

Considering the not-so-simple configuration including power management circuits as a power

supply, Part 19-2 also discusses the indication of specifications of the power supply. With the

establishment of appropriate indications, the three components of the smart sensing unit can

be easily selected and combined from a point of view of a low-power design, when the smart

sensing unit is newly designed and the overall design of the smart sensing unit itself can be

facilitated.

4.1 General

Figure 1 provides a block diagram of the hardware configuration regarding the smart sensor’s

control scheme from the terminal module in the smart sensing unit. The smart sensor’s

control scheme utilizes registers which a digital processing circuit embedded in the smart

sensor possesses. The smart sensor’s control scheme is established by operations in which

both the terminal module and the smart sensor mutually read and write data to the registers.

Each register is of 1 byte. Table 1 provides the byte assignment of the registers in the control

scheme. Here, the name, address, and content of each register are defined, and
