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.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
This first edition of IEC 62386-301 is intended to be used in conjunction with
IEC 62386-101:2014, IEC 62386-101:2014/AMD1:—, IEC 62386-103:2014 and
IEC 62386-103:2014/AMD1:—. The division of IEC 62386 into separately published parts
provides for ease of future amendments and revisions. Additional requirements will be added
as and when a need for them is recognized.
The setup of the standards is graphically represented in Figure 1 below.

3.2
bouncing
tendency of any two contacts in an electronic device to generate multiple signals as the
contacts close or open
3.3
debouncing
any kind of hardware device or software that ensures that only a single signal will be acted
upon for a single opening or closing of a contact
3.4
push button
means for the end user to interact with a lighting control system and known to be in the
released state except while the end user is pressing it, in which case it is in the pressed state
3.5
strictly monotonic
either entirely increasing or decreasing without repeating values
Note 1 to entry: Function f defined on a subset of the real numbers with real values is called monotonically
increasing, if for all x and y such that x < y one has f(x) < f(y), so f preserves the order. Likewise, a function is
called monotonically decreasing if, whenever x < y, then f(x) > f(y), so it reverses the order. For this document
strictly monotonic is defined as either monotonically increasing or monotonically decreasing.
4 General
4.1 General
The requirements of IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—, Clause 4 apply,

with the following restrictions and additions.
9.2 Instance type
The instance type (“instanceType”) shall be equal to 1.
9.3 Input signal and value
The input “resolution” shall be equal to 1.
NOTE 1 A “resolution” of 1 implies that “inputValue” is a single byte variable with possible values limited to 0x00
and 0xFF.
NOTE 2 Since “inputValue” is a single byte variable, the instance will answer NO to “QUERY INPUT VALUE
LATCH”.
“inputValue” shall reflect the state of the push button or binary input, as shown in Table 1.
Table 1 – Meaning of “inputValue”
“inputValue” Push button state
0x00 Released
0xFF Pressed
A bouncing input signal shall be adequately debounced to ensure a single change of
“inputValue”.
9.4 Events
9.4.1 Priority use
The default “eventPriority” shall be priority 3. Since the application controller needs a timeslot
to respond, “eventPriority” should not be set to 2.
9.4.2 Bus usage
9.4.2.1 Instance level
Multiple events from an instance shall not be sent in a transaction.

9.4.2.2 Device level
At the device level events from different instances may be sent in a transaction.

Figure 6 – Button stuck event
Following a button stuck event (see Figure 6), no further events shall occur until the button is
released. This shall lead to maximum one single event, depending on the “eventFilter”.
9.4.6 Event configuration
The application controller may not need all the events mentioned in 9.4.3. The instance shall
allow the application controller to set the “eventFilter” (see IEC 62386-103:2014 and
IEC 62386-103:2014/AMD1:—, 9.7.4) to inhibit those events that the application controller
does not need. For this document, “eventFilter” shall be reduced to one byte.
NOTE Inhibiting events increases the effective bus bandwidth availability.
The “eventFilter” shall have the definition as given in Table 3:
Table 3 – Event filter
Bit Description Value Default
0 Button released event enabled? "1" = "Yes" 0
1 Button pressed event enabled? "1" = "Yes" 0
2 Short press event enabled? "1" = "Yes" 1
3 Double press event enabled? "1" = "Yes" 0

5 Long press repeat event enabled? "1" = "Yes" 1
6 Long press stop event enabled? "1" = "Yes" 1
7 Button stuck/free event enabled? “1” = “Yes” 1

The filter can be set via “SET EVENT FILTER (DTR0)” and be queried using
“QUERY EVENT FILTER 0-7”, see IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—
for details.
9.4.7 Event generation
An event shall be generated on every change of “inputValue” or when required according to a
timer.
In case of system failure all events shall be cleared. Events that occurred during the system
failure shall not be sent after the bus has been restored.

In case the bus is busy, and if during this time multiple events occur, at least the last event
shall be sent.
9.5 Configuring the input device
9.5.1 Setting the timers
Event timers shall be programmable as is indicated in Table 4.
For each timer, a fixed minimum duration and a fixed increment duration are given. The
application controller can set the desired actual timer duration by setting the number of
increments to some value in the range [0,255]. The resulting time shall be strictly monotonic
according to the following formula:
Time = T * multiplier
incr
Only on (re-)starting a timer the actual time shall be calculated based on the corresponding
variable. This implies that the times only change after any running timer has been cancelled
or expired. The tolerance on the time shall be ±5 %.
The T and T timers have device specific physical minimum values to accommodate
short double
techniques that cannot cover the entire range of the timers.

T is 0 ms if the double press event is disabled and “tDouble” is set to 0.
double
The input device shall expose the following commands to set and observe the timer
multipliers:
• “SET SHORT TIMER (DTR0)”, “QUERY SHORT TIMER”;
• “SET DOUBLE TIMER (DTR0)”, “QUERY DOUBLE TIMER”;
• “SET REPEAT TIMER (DTR0)”, “QUERY REPEAT TIMER”;
• “SET STUCK TIMER (DTR0)”, “QUERY STUCK TIMER”.
If the value set for DTR0 is outside the valid range (see Table 9), the instruction shall be
ignored.
If the double press event is disabled and
• “tDouble” = 0: T shall be 0 ms, which implies the short press event is not delayed on
double
a button release;
• “tDouble” ≥ “tDoubleMin”: the short press event is delayed by T on a button release,
double
calculated according to Table 4.
NOTE This feature is useful if some buttons have the double press event enabled, and others not. This still allows
all buttons to send the short press event at the same time.

9.5.2 Manual configuration
If IEC 62386-333 is implemented, the instance variables according to Table 5 may be
manually configured. QUERY MANUAL CONFIGURATION CAPABILITY 3xx (see
IEC 62386-333) shall return the byte as defined in Table 5:
Table 5 – “manualCapabilityInstance3xx” values
Bit Description Value
0 Manual configuration of tShort supported 1 = “Yes”
1 Manual configuration of tDouble supported 1 = “Yes”
2 Manual configuration of tRepeat supported 1 = “Yes”
3 Manual configuration of tStuck supported 1 = “Yes”
4 Reserved 0
5 Reserved 0
6 Reserved 0
7 Reserved 0
9.6 Exception handling
9.6.1 Button stuck
If the button stuck event is enabled, the instance shall set “instanceError” to TRUE, from the
moment the button stuck event occurs until the push button has returned to the released
state. Once the button is in the released state the button free event shall be sent depending
on the “eventFilter”.
9.6.2 Manufacturer specific errors
If a manufacturer specific error is detected, the instance shall set “instanceError” to TRUE,
from the moment the error occurs until the error is gone.
9.6.3 Error value
“instanceError” can be observed via “QUERY INSTANCE STATUS”.
While “instanceError” is set, “QUERY INSTANCE ERROR” shall return “instanceErrorByte”
according to Table 6:
Table 6 – “instanceErrorByte” values
Bit Description Value
0 Button stuck? "1" = "Yes"
1 Reserved “0”
2 Reserved “0”
3 Reserved “0”
4 Manufacturer specific error 1? "1" = "Yes"
5 Manufacturer specific error 2? "1" = "Yes"
6 Manufacturer specific error 3? "1" = "Yes"
7 Manufacturer specific error 4? “1” = “Yes”

If used, the meaning of bits [7:4] of “instanceErrorByte” shall be documented in the
manual/documentation. The impact on event generation shall also be documented.
