  • Page 13: Chapter 1 - Introduction

    Chapter 1 - Introduction 1.1 Overview The WI-I/O 9-U2 range of I/O modules has been designed to provide standard “off-the- shelf” telemetry functions, for an economic price. Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire cable. Although the WI-I/O 9-U2 Series is intended to be simple in its application, it provides many sophisticated features, which will be explained in the following chapters.
  • Page 14 The WI-I/O 9-U2 modules transmit the input/output data using radio or Ethernet. The data frame includes the "address" of the transmitting module and the receiving module, so that each transmitted message is acted on only by the correct receiving unit. Each message includes error checking to ensure that no corruption of the data frame has occurred due to noise or interference.

  • Page 15: Module Structure

    1.2 Module Structure WI-I/O 9-U2 Figure 1 – Module Structure The WI-I/O 9-U2 is made up of a number of basic sections, which all interface with a central Input and output storage area (I/O Store). The I/O Data Store provides storage for I/O data as well as providing services to other processes in the system.

  • Page 16: Getting Started

    There are also a number of Internal I/O that can be accessed from the I/O Data Store. These inputs can be used to interpret the status of a single module or an entire system • Battery voltage – The battery terminal voltage displayed as an Analog value. •...

  • Page 17: General

    2.1 General All WI-I/O 9-U2 Series modules are housed in a plastic enclosure with DIN rail mounting, providing options for up to 14 I/O points, and separate power & communications connectors. The enclosure measures 170 x 150 x 33 mm including connectors.

  • Page 18: Expansion I/O Supply

    The Supply and Battery charging terminals are hosted on the 4-way connector on the bottom edge of the module labelled “Supply” Both Supply and Battery connections have reverse polarity and over voltage protection. The power supply should be CSA Certified Class 2 approved for normal operation. If the device is being used in a Class I Div 2 explosive area, the supply must have Class I Div 2 approval.

  • Page 19: Internal I/O

    Figure 4 – Expansion I/O power & RS485 As a guide when using the I/O power connection from the WI-I/O 9-U2, the number of I/O modules is limited to three x WI-I/O-EX-1-S-11(using inputs), one x WI-I/O-EX-1-S- 12, or one x WI-I/O-EX-1-S-13. If more I/O Modules are required, you will need to calculate the overall current consumption using the following criteria and power the modules from an external supply.

  • Page 21: Radio

    Figure 5 - Earthing 2.3 Radio The following radio variants are available in the WI-I/O 9-U2 dependent on the country of operation. 2.3.1 900 MHz Spread Spectrum radio The radio uses frequency hopping spread spectrum modulation, which is a method of transmitting radio signals by switching the carrier among many frequency channels, using a pseudo random sequence called a hop set.

  • Page 22: 869 Mhz Fixed Frequency Radio (Eu Country Code)

    • Spread-spectrum signals are more resistant to narrowband interference. • They are difficult to intercept or eavesdrop because of the pseudorandom transmission sequences. • Transmissions can share a frequency band with other types of conventional transmissions with minimal interference. 2.3.2 869 MHz Fixed Frequency radio (EU Country Code) This radio operates in the unlicensed fixed frequency band of 869 MHz.
  • Page 23 • USA/Canada 15 miles - 6dB net gain antenna configuration permitted (4W EIRP) • Australia/NZ 12 km - Unity gain antenna configuration (1W EIRP) To achieve the maximum transmission distance, the antennas should be raised above intermediate obstructions so the radio path is true “line of sight”. Because of the curvature of the earth, the antennas will need to be elevated at least 15 feet (5 metres) above ground for paths greater than 3 miles (5 km).

  • Page 24: Dipole And Collinear Antennas

    An antenna should be connected to the module via 50 ohm coaxial cable (e.g. RG58, RG213, Cellfoil, etc) terminated with a male SMA coaxial connector. The higher the antenna is mounted, the greater the transmission range will be, however as the length of coaxial cable increases so do cable losses.

  • Page 26: Yagi Antennas

    Yagi antennas. A Yagi antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path. The Yagi gain also acts on the receiver, so adding Yagi antennas at both ends of a link provides a double improvement.

    2.5.3 Digital / Pulsed Inputs Each digital I/O channel on the WI-I/O 9-U2 can act as either an input or an output. The input/output direction is automatically determined by the connections and configuration of the I/O. If you have an I/O channel wired as an input but operate the channel as an output. No electrical damage will occur however, the I/O system will not operate correctly.

The WI-I/O 9-U2 Analog outputs are a sourcing output and should be connected from the analog output terminal through the device or indicator to Common.

A radio path may act reliably in good weather, but poorly in bad weather - this is called a “marginal” radio path. If the radio path is more than 20% of the maximum reliable distance (see Specification section for these distances), we recommend that you test the radio path before installation.

  • Page 43: Indicating A Communications Problem

    • A module can provide an output, which activates on communication failure to another module. This can be used to provide an external alarm that there is a system fault. 3.3.5 Indicating a Communications Problem There are two ways to indicate communications problems. Fail-to-transmit alarm The first method is to setup a communications indication on a register of your choice when configuring a mapping.

Typically this IP address range does not need to be changed as only WIBMesh Protocol radios can communicate to each other, that is even though the WIBMesh protocol is based around an IP Standards based protocol, it is still not an open standard like Wi-Fi which means you cannot directly connect to the WI-I/O 9-U2 via your PC.

All parameters for this can only be edited from the radio selection itself. 4.3.5 Mappings Mappings are used to send I/O values between WI-I/O 9-U2 modules. The I/O is typically sent via the Radio interface however at times it can be used to be sent via the Ethernet interface between modules.

  • Page 57: Write Mapping

    It should be noted that the ‘Updates’ are only a check signal and care should be taken when configuring the update values with short update times (< 5 seconds) as it will greatly increase the amount of radio traffic. There are three different types of mappings, Write, Gather/Scatter and Read Mappings, which are explained below.

  • Page 58: Figure 39 - Gather/Scatter Mapping

    Figure 39 - Gather/Scatter Mapping Destination – Shows two standard choices as well as a radio IP and an Ethernet IP address for each module in the project. The first choice is ‘Local Host’ which is the standard name given to the address of the loopback network interface and basically means the module you are currently configuring (itself).

    Update Time - This is the period of time that the mapping update messages (check signal) are sent. This is outside of the normal change of state updates that occur when an input changes. Offset Time - Configures an offset time for the update mapping. It is used to stagger the update transmissions so on start-up and every update period the module does not send all mapping at the same time.

  • Page 60: Example Configuration

    To ensure the module outputs get updated with the latest remote input status when first powered on we can configure the module to transmit a special “start-up /force” message which will write a value into an internal register at the remote module/s. The remote module/s can then use this register to force any mappings it has configured for the destination.
