  • Page 4: Introduction To Modbus And Product

    1. INTRODUCTION TO MODBUS AND PRODUCT Thank you very much for purchasing our Lumiplus with MODBUS-RTU features. This manual is intended for professional installer, if you are not, please consult to your official distributor. MODBUS is an open field bus successfully used through the world to connect field devices to a main controller.

  • Page 5: Electrical Connections

    2. ELECTRICAL CONNECTIONS Image 1 Electrical Connection Note: some manufacturers assign for the RS-485 port the “A” connection as a “+”, and “B” as a “-“, while others reverses this nomenclature. The Lumiplus uses the “A” as “+”, and the “B” as “-”. Mind this aspect when connecting to the bus devices coming from different manufacturers.

  • Page 6: Bus Isolation And Termination Resistors

    4. BUS ISOLATION AND TERMINATION RESISTORS If the communication bus is accessible for the user, it shall be double insulated. As far as in general the accessibility of the bus to users will depend on each single installation, safety isolation has been implemented in the Lumiplus physical bus layer.

    Example: Set watchdog triggering time to 30s: Transmit Message: 30 10 00 10 00 01 02 00 1E 7D 59 Where: 30 is the slave address. 10 is the function used. Write Multiple Registers. 00 10 is the address of the first Holding Register to be written. 00 01 is the number of Holding Registers to be written.

  • Page 13: Watchdog Predefined Color/Sequence

    00 Low Byte. Is not considered, 00 is a correct value. FC 80 is the CRC. 7.5.2 Watchdog SETUP and 7.5.3 Watchdog predefined Color/Sequence should be configured in conjunction. See the example 7.5.3 Watchdog predefined Color/Sequence, defining the Color / Sequence to be executed when watchdog triggers.

  • Page 14: Operation Modes

    8. OPERATION MODES 8.1. BASIC MODE In this section it is assumed that a successful connection has been established with the Lumiplus and therefore, address, baud settings and watchdog behavior has been already set. 8.1.1. START PREDEFINED COLOR/SEQUENCE The Start Predefined Color/Sequence, is the color or sequence in which will work the Lumiplus when it Powers ON.

  • Page 15: Checking Current State

    8.1.2. CHECKING CURRENT STATE The state in which the Lumiplus is currently set is available through Status Input Register 0x00. This register has a different meaning for the Low byte and for the High byte. The less significant bit is used to show if an error has occurred and is set to 1 whenever an error exist. Detailed information of the error/errors detected can be requested to the Alarms Input register at 0x01.

If the installation has more than one device connected in the bus, is necessary to change the ID_Adress of the device before connecting another one.
  • Page 25 Name Holding Input Coils Inputs Description Registers Registers Watchdog_time 0x10 This parameter defines the time in seconds that can elapse between the last communication and the actuation of the watchdog. If it is set to 0, the Watchdog is disabled. Range: 0 – 65535.
  • Page 26 Name Holding Input Coils Inputs Description Registers Registers Status 0x00 This parameter indicates in which State is the Lumiplus, and if there is any alarm. The Low byte indicates the alarm and if some light is ON. low byte Alarm .bit 0 0x00 Some alarm has been activated (if it is set to 1).
  • Page 27 Name Holding Input Coils Inputs Description Registers Registers Predefined color 0x25 This parameter determinates the color of the light. Once chosen, a request update color is necessary to see the color change. The colors are from 1 to 12. Predefined Sequence 0x26 This parameter determinates the sequence of the light.

  • Page 28: Troubleshooting Guide

    10. TROUBLESHOOTING GUIDE Problem Solution a) Verify cable polarity A,B. b) Verify ground connection between Master and Slave. c) With a long bus cable, check the termination resistors according with the chapter 4 of this manual. d) Make sure than the baudrate and the bit settings are the same on Master and Slaves.

  • Page 29: Product Revision

    this manual. d) Configure a lower baudrate in Master and Slaves. a) Verify if the "messages error rate" of the bus is too high. b) Verify if the bus is saturated with messages, in this case the time Unexpected WatchDog errors between two messages to the same Slave could be bigger that the WatchDog time configured in the Slave.
