    To maintain the appropriate EMC classification for the intended environment the Ferrite Core supplied with the MelcoREMOTE must be installed onto the antenna cable with 2 loops (Image below), and be located at the boundary of the panel the MelcoREMOTE is installed within.
  • Page 14: Ethernet Connection

    If communication via Ethernet is required then in order to maintain the appropriate EMC classification for the intended environment a cable ferrite (Wurth 74271221S) must be Installed onto the CAT 5/6 cable with 1 loop (Image below), and be located as close as possible to the MelcoREMOTE Ethernet socket. Page 14 of 52...
  • Page 15: Connecting Power

    A double pole (Live and Neutral) 5A switch or circuit breaker must be provided in line with the supply to the MelcoREMOTE power supply and be in close proximity to it. It must be clearly marked as the disconnecting device for the MelcoREMOTE.
  • Page 16: Connecting I/O

    8. Connecting I/O Caution: Only use shielded cables for connecting sensors to MelcoREMOTE, to reduce the possibility of interference with radio communications services. Using shielded cables ensures that you maintain the appropriate EMC classification for the intended environment. All shields must be tied to an appropriate Earth point within the installation panel.

  • Page 22: Connecting Modbus Devices

    Connecting Modbus Devices MelcoREMOTE can act as a Modbus Master device and be configured to communicate with external Modbus Slave devices, to expand its I/O. The following types of Modbus Slave device can be connected to MelcoREMOTE : Devices supporting the Modbus RTU protocol via RS-485 (e.g. MelcoBEMS MINI (A1M)) Devices supporting the Modbus TCP protocol via Ethernet 10.1.
  • Page 23: Modbus Tcp Devices

    (See the Technical specification section for more information). If an external power source is used to power the device, ensure that MelcoREMOTE and the device have a shared ground connection (the RS-485 - terminal can be used for this).
  • Page 24: Server Connection

    11.1. GPRS An active GPRS enabled SIM card needs to be fitted inside the MelcoREMOTE unit to provide a server connection via GPRS. In addition the supplied GPRS antenna must be fitted and screwed firmly into the unit. 11.1.1. Fitting/Replacing a SIM Card Under certain circumstances it may be necessary to fit or change the SIM card in the MelcoREMOTE unit.
  • Page 25 Replace the lid of the unit by pressing down until it has clicked into place. It may be necessary to change the MelcoREMOTE network setting after the new SIM is fitted. See the Configuration and Commissioning chapter for more information on how to do this.
  • Page 26: Ethernet

    Ethernet can be used to connect to the server as an alternative to GPRS. MelcoREMOTE has a 10BASE-T Ethernet controller built in to allow the unit to connect to the server via a corporate Ethernet network, using standard Cat5/Cat6 cable.
  • Page 27: Configuration And Commissioning

    Upon applying power the MelcoREMOTE will beep twice and the LCD backlight will illuminate. After a few seconds the MelcoREMOTE firmware version will be briefly shown before the Status Screen. MelcoREMOTE will immediately attempt to connect and synchronise with the server via GPRS or Ethernet.
  • Page 28: Status Screen

    When using GPRS the current GSM signal strength will be shown in addition to server connection information, when using Ethernet the IP address of the MelcoREMOTE will be shown, when set to be an I/O module the Modbus RTU Slave ID and Baud Rate will be shown.
  • Page 29 When set to GPRS or Ethernet the text in the centre of the screen describes the current connection state. This text will change whilst the MelcoREMOTE establishes a server connection. The sequence of events MelcoREMOTE would typically take to synchronise with the server (using GPRS) are:...
  • Page 30: Password Protection

    The I/O Status and Configuration screens can be protected by means of an optional 4-digit Commissioning Password. When shipped from the factory MelcoREMOTE does not have this password enabled and all screens are freely accessible. After commissioning this password can be enabled and changed to prevent unauthorised access to MelcoREMOTE configuration and output overrides.

    12.7. I/O Status screen The I/O Status screen shows live values for all MelcoREMOTE I/Os (for Variable type I/Os only the ones being logged are shown). When the I/O Status screen is first entered it shows the name and live value for input IN01. The value will update every second.
  • Page 34: External Device I/Os

    External device I/Os are only viewable on the screen if those external devices have been pre-configured. If MelcoREMOTE fails to read a register from an external device its value will show READ ERROR, or if MelcoREMOTE fails to write to a register value WRITE ERROR will be shown.
  • Page 35 The output will remain in the overridden state until either the Back, Up or Down buttons are pressed. At this point the output will resume its previous state from before the Toggle button was pressed the first time for that output. Any control logic set up to control the output will resume.

    Modbus Slave Register tables All MelcoREMOTE I/Os are exposed as both Modbus Input (analogue input) registers and Modbus Holding (analogue output) registers. The register numbers are the same for both register types. Each I/O value is exposed as a 32-bit value, so two Modbus registers are used for each I/O value. The lower of the two register numbers holds the most significant 16-bits of the I/O value.
