  • Page 7: Storage And Handling

    Point Orange User Guide Storage and Handling The Point Orange has an internal lithium thionyl chloride (LTC) battery pack. This is a mature proven primary lithium battery technology that has been deployed globally to power millions of devices. The manufacturer of the cells used in Point Orange have an exemplary track record and excellent design and quality assurance.

    GSM/GPRS modem or a tri-band 3G modem. External connections The Point Orange has 2 external connectors; the first is the main connector at the front, which is used for connecting external sensors and/or the USB cable for configuring or monitoring the RTU.

  • Page 9: Configuration

    Point Orange should operate. For more information on Poco please see the relevant user guides. The Point Orange should be connected to the PC running Poco using the Point Orange configuration cable which connects to the main connector on the Point Orange and a spare USB port on the PC. External IO The Point Orange has 5 IO channels;...

  • Page 10: Points

    ■ When the USB is connected to the Point Orange, the RTU will not go to sleep, as the assumption is that the user is configuring the RTU or wishes to monitor the point values as they are updated. In this instance, all non-loop powered points are updated continuously on a 2 second cycle.
  • Page 11 The second exception is for non-loop powered analogue points that are configured with an alarm. In this instance, the Point Orange will wake up at the frequency specified by the ‘Alarm Check’ setting in Poco. This setting is NOT used for any loop powered sensors.

  • Page 12: External Io

    Digital input The Point Orange can be configured to read up to 5 digital inputs (DI). Each of these inputs is defined as volt-free. i.e. no whetting voltage is required for the change in state to be detected. The DI’s will also accept a 0-2V signal as a digital input.

  • Page 13: Counter Input

    Counter input The Point Orange can be configured to read up to 4 counter inputs (CI). Similar to the DI channels, they are defined as volt-free. The counters are able to count at up to 100Hz and include a debounce filter for use with mechanical switches.
  • Page 14 Point Orange User Guide Active loop The Point Orange can be configured to read up to 2 active loop inputs. An active loop channel provides a 12V DC power supply to power an external sensor and can read a 4-20mA signal from the sensor.

  • Page 15: Serial

    Figure 6: Typical passive loop connections Passive voltage The Point Orange can be configured to read up to 5 passive voltage analogue inputs. A passive voltage channel can read a 0-2V signal from the sensor. Figure 7 shows a typical connection...

    Modbus slave these include 10 digital points, 10 analogues points and 10 counter points. In order to conserve power the Point Orange will only communicate with the slave on a specified trend frequency. This trend frequency is the minimum trend frequency configured on any of the above mentioned Modbus points.

  • Page 18: Available Io

    The number of channels of a particular type is displayed in brackets after each IO type i.e. with no IO configured a Point Orange can have up to an additional 5 Digital inputs, 2 Active loops, 2 passive Loops etc. These numbers are also updated as IO channels are added. The left hand side of Figure 12 shows the IO available with no channels added and on the right an active loop and counter have been added, reducing the overall IO options.

    Point Orange User Guide Connector pin-out The pin numbering scheme of the single 12-pin connector on Point Orange are shown in the following table. Note that many of the pins have multiple uses, depending on how they are configured in Poco as discussed above.

  • Page 23: Internal Io

    Point Orange User Guide Internal IO The Point Orange has a number of internal points that can be read by a master station such as battery voltage, or whether the unit is submerged or not. These conditions are mapped to points and are always available.
  • Page 24 This allows for more frequent sampling of the sensor if desired. Once a submerged reading has been detected, the Point Orange will take a further 5 samples at 10 second intervals. If the average of these six samples has a deviation greater than the threshold then...

  • Page 25: Modem Points

    This digital point is updated by interrupt and is set to 1, when a USB cable is connected between the Point Orange and a PC. This can be used as a tamper detection to determine if and when a local connection is made to the RTU.

    Passive points are sampled every time the RTU wakes up and every 2s thereafter as long as the RTU stays awake. If there is an alarm configured on any of the passive points the Point Orange will wake up at the frequency specified by the ‘Alarm Check’ setting in Poco. Otherwise if there are no Alarms...

    External Counter points. Deadbands When configuring alarms the concept of deadbands is applicable to AI and DI points. There are two types of deadband that are used by the Point Orange, time deadbands and level deadbands. Time...
  • Page 33 Point Orange User Guide deadbands can be applied to both digital and analogue points. Level deadbands are only applicable to analogue points. Time deadbands A time deadband is the time period after an alarm condition has been detected that the event or alarm is raised.

  • Page 34: Trending

    Maximum events If a Point Orange is configured as a DNP3 slave the maximum number of events that can be stored for each class can be configured in the configuration file. If the Point Orange reaches this maximum number of events it will attempt to dial-in to the Master and continue to collect events.

  • Page 35: Time

    UTC time and date. The Point Orange has an integrated RTC that is responsible for maintaining time. When the Point Orange is first powered up or is reset, the time is initialised to the start of Unix time, i.e. 01/01/1970: 00:00:00.

  • Page 36: Communications

    If for any reason the RTU does not get it’s time set, the Point Orange will consider this to be a failed connection and will enter the retry regime.

  • Page 37: Retry Regime

    At the next connection attempt, the Point Orange will use the second IP address in the list. If after trying all IP addresses, the Point Orange cannot contact the master, or if the attempt fails for another reason, such as GSM registration failure, or APN logon failure, then the Point Orange will enter the Retry Regime.

  • Page 38: External Antenna

    RTU will dial-in immediately and the retry regime will reset. External Antenna The Point Orange has 2 antenna options internal or external. The selection of which to use is controlled by software and the user has 3 options, Internal only, External only, or Automatic. The first two options obviously fix the antenna selection to either the internal or external antenna.

  • Page 39: Powering The Point Orange

    Replacement packs are available from Metasphere Ltd. External Battery The Point Orange external battery pack is based on the internal battery pack and can be used to extend the operational life of the unit. For example, high frequency of reading multiple externally powered sensors or to allow lots of calls per day.

  • Page 40: Configuring Point Orange

    If Point Orange does not have a valid configuration it will go into a sleep mode when unplugged from the PC. The Point Orange can only be woken from this mode when connected to the PC via a USB programming cable.

  • Page 48: Installation

    The Point Orange has been designed to minimise the time required to install the unit enabling rapid deployment of the unit in the field. The Point Orange can be installed to a wide variety of sites thanks to its unique design offering 3 different methods: Pipe; Bracket; and Wall. The following sections describe each installation method and when you should consider employing the method.

  • Page 49: Pipe

    (i.e. water, gas etc.) should be determined before installation proceeds. It is the responsibility of the user to ensure that the pipe is suitable for installation. Metasphere accept no responsibility for damage to pipes or other damage as a direct or indirect result of the Point being secured to a pipe.
