How can I communicate with my XL50?

There are two ways to communicate with the xl50 box;  You can use a db9 cable and connect to the serial port, or you can use a USB cable to use the inboard RS232- to USB adapter. If using the comport it is important to verify the configuration of the comport. When using a USB to serial, including the inboard one, it is also really important to make sure that the newest drivers are being used. 

It is important to remember that only a comport can only be used by a single software client at once, so if you need to user xxTerminal, you need to make sure to close xxNetServer and vice versa. 

If further assistance is required please refer to our built in how to documents or quickstart guide 

How do I communicate with the Tool?

Each node in the Tool String must have a unique Node Address. The baud settings need to be the same in all nodes for them to be able to communicate.  To be able to communicate, program and test a tool string you can use an XL-50 box to perform as a translator between the computer and the MWD toolstring. 

If the system baud rates are mismatched you can follow the instructions in our how-to or quick start manuals which will show how to match system baud rates using xxTerminal or xxNetMonitor.

What additional features are provided by the XXT “G2” capability?

The Second Generation xxMWD Firmware, known as xxMWD/G2 or “G2” for short, provides several new features, some of which are compatible with or similar to the qMWD/QDT/GE Version 2 firmware changes:

  • The new “Rotation Monitor” provides the ability to detect tool rotation and measure rotation speed. This process is proprietary to XXT and is designed to minimize additional sensor power consumption when possible.
  • The RPM Down-Linking/Signaling feature provides an alternative method of down-linking simple commands to the tool (non-QDT compatible).
  • The ability to invoke Repeated Synch Word and Repeated Survey Data transmissions can be used to overcome issues associated with lost-circulation conditions (QDT compatible).
  • Short-Flow-Off Telemetry Control can be used to temporarily inhibit survey data transmissions and/or inhibit or limit toolface/logging/steering data transmissions (QDT compatible).
  • Rotating During the Transmit-Delay Interval is another method to optionally inhibit Telemetry Transmissions or to skip survey data transmissions (non-QDT compatible).
  • Dynamic Data Sequences optionally allows changing the content of the telemetry data stream based on whether the tool is rotating (or not) and whether optional focused-gamma instrumentation capabilities indicate uniform gamma count rates while rotating (or not). (QDT compatible).
  • Two additional Toolface/Logging/Steering (Known as “T/L”) Sequence Definition Strings (TSq5 & TSq6) have been added for convenience and flexibility (non-QDT compatible).
  • Use of the QDT-defined ‘y’ format syntax in Sequence Definition Strings has been added for QDT-compatibility when available: This format is used to efficiently telemeter the Log-10 of wide-ranging parameters (such as resistivity) and is functionally equivalent to the XXT ‘x’ telemetry format (‘x’ telemetry format is not QDT compatible).
  • The Gamma High Limit (GaHL) parameter has been added for QDT-compatibility (per GE document OC-TIL-20925052, 08 January 2009). This new telemetry feature is also applicable to xxMPTx/Q V01.50 and xxMPRx/C/PCI V01.50.
  • New Gamma Logging enhancements include an independent Gamma Logging Interval (GaLogI) and an alternative file format gam2Log that increases the maximum data points by a factor of more than 3 (up to 53,144). This enhancement is also applicable to xxMPTx/Q V01.50.

How do I manage the behavior of Battery 2 in the Tool String?

Typically, the Downhole Tool begins by running off from Battery 1, then, as Battery 1 wears down and its voltage drops below a specified voltage threshold, Battery 2 is seamlessly switched in to continue to power the tool along with whatever capacity remains in Battery 1.  The two admin parameters to configure the battery management are listed below and can be set using xxMwdConfig under the battery section. 

  • BThr/BatW –QDT/GE Low Battery Voltage Threshold and Warning Flag
  • BatV/BEvT – Battery Voltage and Battery Voltage Evaluation Time

Additional Information about these parameters and otter battery configuration can be found on the XXT How to and quick start manuals

How do I configure xxSAPC and xxDRT to function as a WITS Server?

Both xxDRT and xxSAPC applications have WITS Server capabilities.  Any parameter within the XXT system can be WITS’d out of a Serial COM Port. Further documentation on how to configure the wits is available on the xxt how to and quickstart documents.

What’s the Depth Server?

Depth Server allows the operators to feed Depth WITS data into the Enteq system, Once Depth data is provided to the xxSAPC/xxDRT, it can serve that Depth data to other PC’s in the system using xxNETserver.

How do I provide logging data to third-party equipment?

Depending on the configuration and resources of the PC you’re using to run the XXT xxMWD/PCTM Program Suite, there are several possible ways for you to connect to 3rd Party equipment for the purpose of providing logging data.  Some of the things to consider are:

  • How many COM Ports do you have on your PC?
  • Do you have an XL50?
  • What kind of cables do you want to use to interconnect things?

XXT has a How-To document that presents three possible methods for interconnecting your PC to third-party equipment and software.

What licenses are required to run the various xxMWD/PCTM Program Suite applications?

An XXT License can reside in an XL50 or in an MPRx.  As long as a valid and sufficient license is detected anywhere in the system/network, any applications requiring such a license can be run. Keep in mind that the license needs to be accessible over the network. For example, if the MPRx in your Laversab 4100 DRT contains your “D” license, but your Wireless Connection to the 4100 is not functioning correctly, any applications you may be running on your Safe Area PC (SAPC) are not able to see the license, and thus are not be able to run.

No XXT License is required to run the following xxMWD/PCTM Program Suite applications:

  • vmIndicator/PCTM
  • vmAnalyzer/PCTM
  • xxMemIO/PCTM
  • xxDirKTutility/PCTM
  • xxPCNodeInfo/PCTM
  • xxNETserver/PCTM
  • xxNETmonitor/PCTM
  • xxMWDWaveformAnalyzer/PCTM

An XXT “B” or “D” License is required to run the following xxMWD/PCTM Program Suite applications:

  • xxMWDconfig/PCTM
  • xxRollTest/PCTM
  • xxToolTest/PCTM
  • xxTFOutility/PCTM

An XXT “D” License is required to run the following xxMWD/PCTM Program Suite applications:

  • xxDRT/PCTM

How do I configure and use the Gamma functionality of the XXT DIM?

When considering Gamma, it’s important to keep in mind that the following three Gamma-related activities are distinct and can operate largely independently of each other:

  • Gamma Measurement/Acquisition (updating of the system parameter “Gamma”)
  • Gamma Logging (downhole logging of Gamma Data)
  • Gamma Telemetering (timing and resolution of the Gamma value telemetered)

There is a collection of parameters that address each of the above aspects, and in some cases, there are interdependencies between various parameters. XXT has a How-To document that explains how to configure and use the Gamma capabilities of the XXT DIM:

How To Configure the Gamma Parameters of the XXT DIM

It is available for viewing by clicking the document name above.  How-To documents are also always available to you via the menu bar in any XXT PC Suite application via the Help > How-To Notes menu item.

How do I download the configuration that’s stored in my Tool into a file for analysis?

When troubleshooting a problem where a Tool doesn’t seem to be behaving correctly, it is very important to review the configuration that’s actually stored in the Tool itself, as opposed to simply reviewing the configuration file that is believed to have been used to configure the Tool.  To do this:

  • Connect the Tool to your PC via an XL50
  • Confirm that all Tool Nodes are communicating by issuing a [##]asw?  command
  • Open xxMWDconfig and wait for it to initialize
  • Click the teal-colored Download box on the xxMWDconfig screen, follow the prompts
  • This causes the Configuration stored in the Tool to populate the fields of the various xxMWDconfig parameter groups.
  • From the xxMWDconfig Menu Bar, click File > Save As and select a file name and path that suits you.
  • The Tool’s configuration can now be reviewed from within xxMWDconfig, or by looking at the config file (.cfg extension) that you saved off.

When contacting XXT for help with a problem, please supply us with the Configuration File which you have downloaded from the Tool.

How can I display parameter names and values I’m interested in on xxSAPC/xxDRT?

xxSAPC and xxDRT have an area of the screen just to the right of the Compass Rose called Data Tabs. There can be up to four user configurable Tabbed screens which can be populated with any parameters of interest to the user. Just right-click in the Data Tabs field and select Setup Data Tabs.

What’s the difference between Gravity Toolface (gTFA), Magnetic Toolface (mTFA), and Automatic Toolface (aTFA)?

The Toolface Angle, as computed using the signals from the Directional Sensor’s Magnetometers is referred to as Magnetic Toolface or mTFA. The Toolface Angle, as computed using the signals from the Directional Sensor’s Accelerometers is referred to as Gravity Toolface or gTFA. Whether mTFA or gTFA is the more useful of the two TFA types is determined by the measured Inclination of the Tool.  When the Tool’s Inclination (Inc) is less than the Inclination Threshold (IncT), then mTFA is more useful, otherwise gTFA is more useful. IncT is configured in the Telemetry Settings group of Configuration Parameters. When aTFA appears in the Toolface/Logging (Steering) Sequence String, it means that the TFA that’s being sent is either gTFA or mTFA, depending on whether Inc is greater that IncT or not, respectively, and can select between them dynamically on the fly, automatically giving the driller the most useful TFA.
