1. INTRODUCTION TO MODBUS AND PRODUCT
Thank y u very much f r purchasing ur Lumiplus with MODBUS-RTU features. This manual is
intended f r pr fessi nal installer, if y u are n t, please c nsult t y ur fficial distribut r.
MODBUS is an pen field bus successfully used thr ugh the w rld t c nnect field devices t a main
c ntr ller. This is the reas n why MODBUS has been ur ch ice t ffer t ur cust mers and
partners an aut mated s luti n easy t integrate n t nly with ur brand pr ducts but als with a
vast c llecti n f third party c mp nents and c ntr llers
MODBUS, MODBUS-RTU and ther related names are registered trademarks f MODBUS
Organizati n. Further inf rmati n and d cumentati n can be f und at http://www.M dbus. rg/
1.1. PRINCIPLE OF OPERATION
The Lumiplus implements MODBUS-RTU as a c ntr l-c mmunicati ns feature that all ws its
perati n and supervisi n tasks fr m a MODBUS aut mati n envir nment. Preventive maintenance
and fault analysis is als p ssible thanks t the implementati n f internal registers in the Lumiplus
with the m re relevant perati nal and err r events.
Whenever the Lumiplus is installed, y u are n t f rced t c nnect it t a MODBUS system, as far as
y u d n t aim t c ntr l r supervise it externally. The Lumiplus can run in l cal m de, as
traditi nally d ne, with ut using the MODBUS layer.
H wever, we expect that the implementati n f MODBUS-RTU in the Lumiplus will pen t ur
advanced cust mers and partners a wide range f new pp rtunities and implementati n scenari s
thanks t the simplicity and flexibility f the MODBUS-RTU layer.
Using a MODBUS-RTU message, the Lumiplus can change t a specific c l r, sequence r vel city,
rep rt err rs, hist rical data and s n, giving t the user/installer a wide range f new features
based in the aut mati n f an already existing and pr ved Lumiplus.
1.2. BASIC CHARACTERISTICS
The MODBUS c mmunicati n system pr vides a Master/Slave implementati n am ng devices sharing
a physical c nnecti n. F r the Lumiplus, the physical c nnecti n is a RS485 half duplex serial layer,
which has been ch sen am ng ther pti ns due t its wide implementati n and r ughness.
F r the Lumiplus, a RS-485 half duplex wired c nnecti n has been implemented and the pr ject r is
designed t run in a single-master system. In this implementati n, Master and Slave figures has a
clear r le that is crucial t clear understand f r a pr per system implementati n.
Master Device: Device that c ntr ls the data exchange in the bus and, if necessary, implements c -
rdinati n tasks am ng different slaves (i.e. PLC Pr grammable L gic C ntr ller, SCADA, etc).
Slave Device: Devices c nnected t the bus that attends t the requests fr m the master, either
rep rting inf rmati n r executing tasks as per Master request.

2. ELECTRICAL CONNECTIONS
Image 1 Electrical Connection
N te: s me manufacturers assign f r the RS-485 p rt the “A” c nnecti n as a “+”, and “B” as a “-“,
while thers reverses this n menclature. The Lumiplus uses the “A” as “+”, and the “B” as “-”. Mind
this aspect when c nnecting t the bus devices c ming fr m different manufacturers.
3. CABLE CHARACTERISTICS
The rec mmended wiring f r a MODBUS-RTU C mmunicati n is based in a linear structure, active
bus with terminati n at b th ends. Is p ssible c upling and unc upling f devices during perati n
with ut affecting ther devices. The wire shall be twisted and shielded acc rding t EN 50 170.
The values f transmissi n rate supp rted f r the device, all w maximum cable length f 1,200 m
with ut repeaters, r up t 10 km using repeaters, when installati n is acc rding t the standard.
F r the balanced pairs used in an RS485-system, a Characteristic Impedance with a value higher than
100 Ohms may be preferred, especially f r 19200 and higher baud rates.

4. BUS ISOLATION AND TERMINATION RESISTORS
If the c mmunicati n bus is accessible f r the user, it shall be d uble insulated. As far as in general
the accessibility f the bus t users will depend n each single installati n, safety is lati n has been
implemented in the Lumiplus physical bus layer. M re ver, f r safety purp ses, it is rec mmended t
ensure that ther devices sharing this bus als implements this insulati n.
Additi nally, the use f bus insulated devices n t nly enhances the security level, furtherm re
increases the equipment reliability, larger immunity t electr magnetic interference, l nger life,
higher reliability, m re stability ver the range f temperatures.
Whenever single r multiple devices are c nnected sharing a bus physical c nnecti n, it is
rec mmended t use terminating resist rs at the ends f the bus, even m re when use large cable
length r high speed data rates. The terminating resist r is used t prevent an RF signal fr m being
reflected back fr m the end, causing interference. The terminating resist r must be in b th ends f
the bus, c nnected in parallel (as sh wn in the image bel w). A typical value f this resistance is
120Ω, 0.5W. The value f the resist r must be the same in b th ends. The terminating resist rs are
the resist rs ܴ

7. DEVICE DESCRIPTION AND CONFIGURATION
7.1. GENERAL DESCRIPTION
If a request is made thr ugh M dbus and later an ther ne with the rem te c ntr l, the M dbus will
indicate the c l r set thr ugh M dbus, it is because the unidirecti nality between M dbus m dule
and the Lumiplus m dulat r c ntr lled tr ugh rem te c ntr l.
When a simultane us request is made thr ugh M dbus and rem te c ntr l, and there is n c nflict,
the last request will take effect.
In general, there is n t check n the c nstancy f the values sent t specific registers. Theref re is the
perat r resp nsibility t check that c nsistency.
In this manual, the numbers in hexadecimal have been represented with the f rmat 0xZZ, where ZZ is
the number.
The register map that g verns the7.2 State Machine Diagram and all that is explained bel w is in the
chapter 9 Basic M dbus-RTU register map.

7.3. ADDRESS AND BAUD RATE SELECTION
7.3.1. ADDRESS SETTING
The address f the Lumiplus in the bus is set thr ugh the 0x00 H lding Register.
ID_Address: Address f the Lumiplus in the bus.
Fact ry setting: 0x30.
Suggested range: 0x30 - 0x3F.
The fact ry default f r the Lumiplus is (0x30). H wever y u can change this value by sending writing
this h lding registers and as far as y u check t d n t intr duce c llisi ns r c nflicts with ther
slave’s addresses.
Example: changing the address ID fr m 0x30(default) t 0x31.
Transmit Message: 30 10 00 00 00 01 02 00 31 3E 15
Where:
30 is the slave address. (The actual ID address).
10 is the functi n used. Write Multiple Registers.
00 00 is the address f the H lding Register t be written.
00 01 is the number f H lding Registers t be written. 1 in this case.
02 is the number f bytes f data t be sent.
00 31 is the new ID address.
3E 15 is the CRC.
7.3.2. BAUD RATE SELECTION
The Baud Rate selecti n f the serial c mmunicati ns with the Lumiplus set thr ugh the 0x01 H lding
Register. By default, 9600 bps and 8E1 (8 data bits, Even Parity, 1 st p bit) is implemented. H wever,
19200 bps and 2 st p bits are als supp rted (when NO parity is implemented).
The reas n f r supp rting N2 frames is t keep the MODBUS standard requirement f sending eleven
bits per byte ( 1 start + 8 data + 1 parity + 1 st p). Whenever a N parity c nfigurati n is ch sen, then
2 st p bits are intr duced t keep the eleven bits per byte required by the standard.
F r c mpatibility reas ns, N1 frames are als supp rted. H wever, mind that using this selecti n y u
are n t fulfilling the MODBUS standard requirements as far as nly ten bits per byte are used.
Acc rding t this, the baud rate and frame selecti n is c mpleted defining the baud rate (in bauds),
number f data bits, parity and number f st p bits.

7.4. BROADCASTING
Br adcasting is n t supp rted by the Lumiplus.
7.5. WATCHDOG
The watchd g is a feature implemented in the Lumiplus aimed t check if the c mmunicati ns in the
bus keep alive. This is meanly a safety feature intended t detect a fail in the c mmunicati ns, and
all ws changing t a predefined state.
The Watchd g is triggered when the device d es n t receive tw messages in less than watchd g
time specified.
Acc rding t these descripti ns, either the time c nsidered f r triggering the watchd g as well as h w
t pr ceed then, needs t be defined.
If the watchd g has been activated, any request thr ugh M dbus will n t be made. In this State, the
Lumiplus nly can be read, and will n t accept changes. The alarm f the watchd g in h lding register
0x20 will be at 1; nly setting this alarm t 0 thr ugh M dbus r switching OFF the p wer supply,
Lumiplus will all w changes r requests.
T all w c rrect err rs if a bad c nfigurati n f the watchd g has been d ne, the first 30 sec nds f
the P wer ON f Lumiplus, the watchd g will be st pped. This all ws the user t change the
watchd g time if a sh rt time has been c nfigured, r all ws t deactivate the watchd g.
7.5.1. WATCHDOG TRIGGERING
The watchd g triggering time is defined in the H lding Register 0x10. This time is set in sec nds. 0s
means watchd g is disables. This is the default value.
T enable the watchd g feature, set the watchd g time t a value different fr m 0. H wever, mind
the implicati ns f this value as l ng times may deal t useful setups.

12
Example: Set watchd g triggering time t 30s:
Transmit Message: 30 10 00 10 00 01 02 00 1E 7D 59
Where:
30 is the slave address.
10 is the functi n used. Write Multiple Registers.
00 10 is the address f the first H lding Register t be written.
00 01 is the number f H lding Registers t be written. 1 in this case.
02 is the number f bytes f data t be sent.
00 1E is the value t be sent. 30 in decimal.
7D 59 is the CRC.
N w, the watchd g time is set t 30s. Theref re, whenever tw pr perly c nstructed messages are
read in less than 30s, even n t addressed t the Lumiplus, the watchd g is n t triggered. Otherwise, it
is triggered.
T kn w the Watchd g time, is necessary read the h lding registers.
The resp nse f the Watchd g_time, in this case, will be: 30 03 02 00 1E 45 88
30 is the slave address.
03 is the functi n used. Read h lding registers.
02 is the number f bytes f data t be read.
00 1E is the time c nfigured. 30 in decimal.
45 88 is the CRC.
7.5.2. WATCHDOG SETUP
The Watchd g Setup, register 0x11, must be setup in c njuncti n with the Watchd g triggering
register, and the watchd g predefined c l r/sequence.
The High Byte f the register defines h w t pr ceed when the Watchd g is triggered. If it is set t 0,
then the Watchd g predefined c l r/sequence will be c nsidered. If it is set t 1, then the
c mmunicati n bridge is reset.
The Low Byte is n t c nsidered in this functi n. Set it t 0.
Example: C nfiguring the watchd g t d the defined in the watchd g predefined c l r/sequence:
Transmit Message: 30 10 00 11 00 01 02 00 00 FC 80
Where:
30 is the slave address.
10 is the functi n used. Write multiple registers.
00 11 is the address f the first register t be written.
00 01 is the number f registers t be written. 1 in this case
02 is the number f bytes t be sent.
00 High Byte. The watchd g will d the defined in the Watchd g predefined c l r/sequence.

13
00 L w Byte. Is n t c nsidered, 00 is a c rrect value.
FC 80 is the CRC.
7.5.2 Watchd g SETUP and 7.5.3 Watchd g predefined C l r/Sequence sh uld be c nfigured in
c njuncti n. See the example 7.5.3 Watchd g predefined C l r/Sequence, defining the C l r /
Sequence t be executed when watchd g triggers.
7.5.3. WATCHDOG PREDEFINED COLOR/SEQUENCE
The watchd g predefined c l r sequence, H lding Register 0x14, determines the c l r r the
sequence predefined when the watchd g triggers.
The High byte set the speed f the sequence, it can take values fr m 0 t 8. If it is set t 0, the speed
will be 0, which means that a c l r is fixed.
The Low Byte sets the color if the High Byte is 0, r the sequence if a different value f 0 is set in the
High Byte. The L w byte, can take values fr m 0 t 12, these are 12 p ssible c l rs r 8 p ssible
sequences, t be ch sen. If the L w Byte is set t 0 n c l r has been selected, which means that the
Lumiplus has n lights turned ON.
If the register is c nfigured like (0xFFFF), the luminaries remain with the c l r / sequence previ us f
the alarm state.
Example:
Set watchd g predefined c l r/sequence in case that watchd g is triggered, in this example the
Lumiplus will has all the lights turned OFF, and the Status when triggers will be Watchd g:
Transmit Message: 30 10 00 14 00 01 02 00 00 FC D5
Where:
30 is the slave address.
10 is the functi n used. Write multiple registers.
00 14 is the address f the first register t be written.
00 01 is the number f registers t be written.. 1 in this case.
02 is the number f bytes t be sent.
00 High Byte. is the speed, 0 is a fixed c l r.
00 L w Byte. C l r 0 ch sen. (C l r 0 nly exist in the watchd g predefined c l r/sequence,
and in the Start predefined c l r/sequence) there is n c l r, which means turn OFF the
lights.
F5 D5 is the CRC.
NOTE: Mind that watchd g functi n is implemented f r safety reas ns. H wever, the reas ns f r
activating it, r n t, depends n the installer/integrat r criteria. Always, mind f implicati ns n what
is being implemented. Use this feature under y ur resp nsibility.

14
8. OPERATION MODES
8.1. BASIC MODE
In this secti n it is assumed that a successful c nnecti n has been established with the Lumiplus and
theref re, address, baud settings and watchd g behavi r has been already set.
8.1.1. START PREDEFINED COLOR/SEQUENCE
The Start Predefined C l r/Sequence, is the c l r r sequence in which will w rk the Lumiplus when it
P wers ON.
The High byte set the speed f the sequence, it can take values fr m 0 t 8. if it is set t 0, the speed
will be 0 which means that a c l r is fixed.
The Low byte sets the color if the High byte is 0, r the sequence if a different value f 0 is set in the
High Byte. The L w byte can take values fr m 0 t 12, these are 12 c nfigured c l rs, r 8 sequences.
If it is set t 0, any light will be ON when the Lumiplus p wers ON.
If the register is c nfigured like (0xFFFF), the luminaries remain with the c l r / sequence previ us f
the last OFF.
The way t setting this parameter is the same that the Watchd g predefined c l r sequence, the nly
difference is the number f the h lding register, in this case the h lding register is 0x15.
In the Start Predefined C l r/Sequence and in the Watchd g predefined C l r/Sequence, is n t
necessary t make a request update t change the c l r, when the system Starts r, the watchd g
actuates.
Specific c l r requests and sequences are defined acc rding t the f ll wing c dificati n:

15
8.1.2. CHECKING CURRENT STATE
The state in which the Lumiplus is currently set is available thr ugh Status Input Register 0x00. This
register has a different meaning f r the L w byte and f r the High byte.
The less significant bit is used t sh w if an err r has ccurred and is set t 1 whenever an err r exist.
Detailed inf rmati n f the err r/err rs detected can be requested t the Alarms Input register at
0x01. Only the watchd g alarm has been implemented, which means that if an err r exist, surely is a
watchd g err r (watchd g has been triggered). Further t the raising f an err r the Lumiplus rep rt
an unrec verable err r that needs t p wer ff-p wer n t reset, r set the alarm t 0.
Until the alarms have been reset, the Lumiplus will n t accept any change, and nly will resp nse
inf rmati n (read nly).
The High Byte is used t sh w the current state f the Lumiplus.
The c des f r the different states implemented in the high byte are sh wn in the f ll wing table:
0x00 Start.
0x01 Watchd g.
0x02 Request C l r.
0x03 Request Sequence.
Mind the unidirecti nality described in chapter 7.1 General Descripti n.
C ding Examples (High byte first):
0x0002 2 Start State. ON, N err r.
0x0101 257 Watchd g State, Alarm. Light OFF. Reset needed. (This casuistic is p ssible
when the watchd g predefined c l r/sequence is c nfigured t turn OFF the lights).
0x0103 259 Watchd g State, Alarm. Light ON. Reset needed. (This casuistic is p ssible
when the watchd g predefined c l r/sequence is a c l r r sequence).
Example:
T kn w in which State is the Lumiplus, the transmit message must be:
30 04 00 00 00 01 35 EB
Where:
30 is the slave address.
04 is the functi n used. Read input registers.
00 00 is the address f the first input register t be read.
00 01 is the number f input registers t be read, 1 in this case.
35 EB is the CRC
The resp nse is 30 04 02 00 02 45 35, that indicates Start M de, with ut alarm, and light ON.
Where:

16
30 is the slave address.
04 is the functi n used. Read input registers.
02 is the number f bytes t be read.
00 is the high byte, it indicates that is in Start M de
02 is the l w byte, it indicates s me light is ON.
45 35 is the CRC.
In the example bel w, the time watchd g has been activated and the time with ut c mmunicati ns
has exceeded the watchd g time:
The resp nse is 30 04 02 01 01 04 A4, that indicates Watchd g State with watchd g alarm.
Where:
30 is the slave address.
04 is the functi n used. Read input registers.
02 is the number f bytes t be read.
01 is the high byte, it indicates that is in Watchd g state.
01 is the l w byte, it indicates that there is s me alarm.
04 A4 is the CRC.
8.1.3. ACTUATOR CHANGE REQUEST
Actuat r change request can be sent t the Lumiplus thr ugh the H lding Register 0x21. H wever,
these requests can als be sent using a bit address m de starting n c il bit 0x210. Mind that y u can
ch se either register address m de r bit address m de. H wever, f r clarificati n purp ses and t
av id misunderstandings, y u sh uld n t mix b th appr aches as far as y u d n t have a clear idea
n what are y u d ing.
8.1.4. REQUEST ON
T turn ON the lights f Lumiplus thr ugh MODBUS, the simplest way is setting t 1 the c il 0x210.
Example, bit address m de:
Transmitting message: 30 0F 02 10 00 01 01 01 ED AE
Where:
30 is the slave address.
0F is the functi n used. Write multiple c ils.
02 10 is the address f the first c il t be set.
00 01 is the number f c ils t be set, 1 in this case.
01 is the number f bytes f data t be sent.
01 is t set the request, and then turn ON the lights.
ED AE is the CRC.
Example, byte m de, H lding Register:

17
Transmitting message: 30 10 00 21 00 01 02 00 01 38 B0
Where:
30 is the slave address.
10 is the functi n used. Write multiple registers.
00 21 is the address f the first H lding Register t be set.
00 01 is the number f H lding Register t be set, 1 in this case.
02 is the number f bytes f data sent
00 01 is the data send.
38 B0 is the CRC
8.1.5. REQUEST OFF
T turn OFF the lights f Lumiplus thr ugh MODBUS, the simplest way is setting t 1 the c il 0x211.
Example:
Transmitting message 30 0F 02 11 00 01 01 01 D0 6E
Where:
30 is the slave address.
0F is the functi n used. Write multiple c ils.
02 11 is the address f the first c il t set.
00 01 is the number f c ils t be set, 1 in this case.
01 is the number f bytes f data sent.
01 is t set the request, and then turn OFF the lights.
D0 6E is the CRC.
Als , is p ssible t make a Request OFF by setting the H lding Register 0x21 t 0x02
8.1.6. CHANGING COLOR
T change the c l r f the Lumiplus thr ugh M dbus, is necessary t c mplete tw steps, these
steps, where n t necessary in the Watchd g and Start Predefined C l r/Sequence.
1. It is necessary to choose the prede ined color.
2. It is necessary to make a Request Update Prede ined Color.
Choosing the prede ined color:
The way t ch se the c l r is using the Requests H lding Register (0x25).
There is 12 predefined c l rs t ch se. Fr m 0x1 t 0xC (fr m 1 t 12) acc rding t the table ab ve.

18
Example:
Transmitting message 30 10 00 25 00 01 02 00 01 39 34
Where:
