  1. Yokogawa Network Solutions Presents: DXAR4 (DAQStation Advanced) Quick Start Guide The following guide is designed to help the user take a DAQStation as it arrives from the factory and quickly get an input channel and math channel configured for measurement and recording and then display the results in real-time. This guide does not cover wiring instruments and transmitters to input channels as well as wiring any alarm relay signals. For the sake of this guide a thermocouple was wired to input channel one and a calibrator was used to provide a 1-5VDC process signal.

  2. Default DX2000 R4 Display After the DX2000 R4 Boots up for the first time, the following trend screen will appear. By default channels are set to 2V range and will display floating values without any instruments or transmitters attached.

  3. Date/Time Settings The DX2000 records all samples with date and time stamps – so it is important to set the correct date and time in the unit. Also ensure that the appropriate Daylight Saving Time is set in the recorder as well as any PC that is going to be viewing data. Time zone will be set on a different screen. Failing to set Daylight Saving Time and time zone correctly can result in an offset when viewing data.

  4. Time Zone Setting Setting the appropriate time zone on PCs used for viewing data and on DAQStations is an important part of configuration to avoid offsets in recording times. Time zone can be specified in the Basic Setting Mode – press Menu then Func for three seconds from trend screen.

  5. Basic Network Configuration The DAQStation has powerful network support and in order to make this available – it must be assigned an IP address. The majority of users will assign a static or fixed IP address to a unit. Ensure that the address is in the same networking range as PCs hoping to connect to it (e.g., first three sets of numbers – 192.168.1.X should match with only the last number being different. Subnet mask is usually 255.255.255.0 and default gateway is optional. DHCP can be used for automatic address assignment if your network support this (talk to your network group). Press DISP/ENTER to accept changes.

  6. Optional Web View Configuration Once placed on a network, a DAQStation can be configured to be seen on any web browser. Security can be enabled by turning Access control on – a user name and password will be required to view the web page. It is important to note that any navigation conducted through the web browser will be mirrored on the DAQStation – so local operators will see remote interactions. The web view does not allow menu level configuration changes.

  7. Operating Environment Configuration Configuring the Operating environment is an important part of DAQStation configuration. It is especially important to set the Temperature unit as changing this at a later point after channels have been configured will require reconfiguration of channel settings.

  8. Optional Media FIFO Setting The DAQStation has a FIFO (First In First Out) management feature that allows the compact flash to always have the latest file sets on it. When Media FIFO is enabled – as the compact flash card gets filled up, the oldest data file will be removed to make room for a new data file. Media FIFO can be combined with the automatic file transfer capability of the DAQStation to ensure that there is always room for new data and that old files are backed up to a network server via FTP (File Transfer Protocol).

  9. Store Settings and Exit Basic Setting Mode Once all changes have been made under Basic Setting Mode – select End to exit back to the trend screen. Remember that whenever making changes on a particular screen that you press DISP/ENTER to accept the changes (yellow background for changed items will turn back to white).

  10. Measurement Channel Configuration Part 1 Channels can be configured individually (set First-Ch) or as spans (set First-Ch and Last-CH). Each channel can be configured with multiple modes with the most common being TC for Thermocouples and 1-5V or process signals (including 4-20 mA across a 250 Ohm shunt resistor applied across +/- input terminals). Up to 4 alarms can be associated with a channel and alarms can trigger optional output relays or internal memory bit switches (can be used within math or to trigger Events). Press DISP/ENTER to accept changes.

  11. Measurement Channel Configuration Part 2 DAQStations support scaled process signals. A common signal range is 1-5V or 4-20mA. Decimal places count towards the Scale Lower and Upper limit (-30000 to 30000) so be sure to eliminate unnecessary decimal places in order to scale for larger process ranges (always start with Lower Scale first when removing decimal places). An optional Low-cut can be used with signals like flows in order to prevent negative flow rates that could affect flow totals.

  12. Tag Naming, Memory Sampling and Alarm Delays Each channel can be assigned a name and if display by tagname was chosen under Basic Setting Mode – Environment settings then these tagnames should appear on the trends. Press DISP/ENTER to accept changes.

  13. Optional Math Channel Configuration DAQStations can be purchased with a powerful math capability (/M1 option). The math option is required to add offsets to measurement channels, calculate flow totals, as well as other logical and arithmetic operations. The example shown here is a typical equation used to calculate the flow total from an input channel. The example also includes a flow total reset at a predefined value.

  14. Optional TLOG Timer Configuration Whenever using a TLOG math statement – it is important to configure the timer associated with the channel. In this case a timer has been configured to allow for a TLOG.SUM(2) of a flow rate attached to input channel 2 that is flowing and totalizing at a per minute rate.

  15. Trend /Save Interval The DAQStation can create two types of data files – a Display Data file (default shown here) and an Event Data file (must be configured under Basic Setting Mode). The Display Data file is designed to simulate a paper trend and records the min/max for each point at a predefined interval (similar to a pen dragging up and down on a paper chart). The Save interval determines how often a new data file will be created. When recording, a progress bar at the top will show how far along a specific file is before complete.

  16. Setting Group Names, Channels, and Trip Lines Once the channels have been configured – they can be added to Groups (sets of points that are displayed together). A group can have up to 10 channels in it on a DX2000. Delete any channels that are not needed from the CH set. Trip lines can also be set on this screen. Press DISP/ENTER to accept changes.

  17. Optional Event Action Configuration The DAQStation has a powerful Event/Action system that allows specific events to trigger various actions. In this case an example event/action has been created to cause a math reset when internal bit switch S01 is triggered (see the optional Math Channel configuration where a flow total was configured with an alarm at 50000000 gallons). Press DISP/ENTER to accept changes.

  18. Saving the Configuration After making all these changes to the DAQStation configuration it is important to save the changes. Configuration can be saved to a compact flash card or to a USB memory stick (if the USB option was purchased).

  19. Recording and Trending Now that the DAQStation has been configured you can activate its recording and math functions (if unit has the math option). Press the Start button to begin recording and start math. Indicators at the top will show a count-down until the file is closed out as well as if the unit is recording and whether math is active. The Group name currently being viewed is in the top left and the tag names with digital values will appear on the right.

  20. Navigating Operator Menu Once the DAQStation is up and running, operators can navigate between different groups by pressing the right/left arrow keys or different modes of view by pressing the up down arrow keys. The full operator menu can be accessed by pressing the DISP/ENTER key.

  21. Function (Func) Key The DAQStation Func key can be used to execute various commands like Alarm Acknowledgements and Snap Shots. It is also a good idea to use the Func – Media eject whenever removing a USB or Compact Flash from the unit.

  22. Optional Web Interface If the DAQStation was configured for network used and the Web interface was activated and it has been connected to a network then entering its IP address into a Web Browser should allow the DAQStation to be remotely viewed. Be aware that navigating with the web interface will be reflected on the local DAQStation.
