VEGA DTM Collection

The VEGA DTM Collection is the adjustment software for all communication-capable VEGA instruments. The software package consists of PACTware, the VEGA DTMs, the VEGA DataViewer as well as various standard communication DTMs.

A Bluetooth driver also enables wireless communication with Bluetooth-capable VEGA instruments like the display and adjustment module PLICSCOM. A VEGA Bluetooth USB adapter is available for PCs without an integrated Bluetooth module.

The full version DTM collection is now free for everyone

Simplicity for the user – that’s an important guiding principle at VEGA. It also applies to the many tools that are available for operating sensors and other devices. From October 2023, the range of capabilities will be considerably expanded.
Examples of setup and commissioning

Components of the VEGA DTM Collection


The DTM (Device Type Manager) is the actual adjustment module of the sensors and field components. It contains all device-specific data and functions of a sensor type and provides all graphic elements and dialogues needed for adjustment. A DTM is not a stand-alone, executable software – it can only be used with a supporting programme like PACTware.


PACTware is a manufacturer and fieldbus independent software for operation and adjustment of all types of field instruments. The DTMs of the corresponding field device manufacturers are integrated into this open and freely available supporting programme via interface specification FDT 1.21/2.0/3.0.



FDT (Field Device Tool) is a standardised software interface that describes the interaction between the DTM and the frame application. FDT regulates the exchange of data.


VEGA DataViewer

VEGA DataViewer is a very helpful tool for analysing, displaying, managing and archiving DTM data.
VEGA Data Viewer is installed locally on the device and can also be linked to myVEGA.
The data can be conveniently stored there and accessed at any time – from any adjustment device.



  • Project assistant
  • Security
  • Diagnosis
  • Local storage
  • Backup & restore

Setup and commissioning

  • Application
  • Min./Max. adjustment
  • Linearisation
  • Current output


Backup files can be saved locally on the end device and treated like any other file – they can be copied, archived and sent, for example.


  • Service recordings
  • Contact to customer service

Project assistant

The project assistant automatically identifies the connected instruments and integrates them into the PACTware project. All that’s required is an online connection to the corresponding instruments.


To protect against unauthorised changes to the set parameters, a sensor can be locked via a PIN. The lock applies to the display and adjustment module, DTM adjustment and fieldbuses.

With the “PINs and Codes” service provided by myVEGA, access codes and instrument codes can also be stored securely. Access from any adjustment device is convenient and possible at any time. 


  • Sensor status
  • Measured value status
  • Status of additional measured values (electronics or measuring cell temperature)
  • HART communication status messages
  • Drag pointer with maximum and minimum measured value, including time
  • Status signals according to NE 107 and VDI/VDE 2650
  • Instrument documentation as PDF – for saving or printing

Local storage

  • Measured value memory:
    The measured value memory in the instrument stores the measured values over a certain period of time and can be read out at a later time.
  • Event memory:
    The event memory saves all events that have occurred in the sensor, such as error messages or parameter changes. These events can be read out from the sensor at any time with date and time stamp, providing an overview of the instrument status.

Backup & restore

With the function “Backup & Restore”, all important VEGA sensor data can be saved and restored over an unlimited period of time. The data can be called up and – if the user so chooses – reinstalled, which brings more efficiency to automated processes. 

Functions of the VEGA DTMs

Application description

Under “Application”, the sensor is adapted to the particular ambient conditions the measuring task is operating under. In dependence on the entries made in this window, certain parameters are automatically set to enable optimal measurement. It is therefore advisable to select the setting that best suits the conditions the sensor will face.

  • Medium type: “Liquid” or “Bulk solid”
  • Medium: Depending on what the user selects under “Medium type”, a number of appropriate media are listed that the user can choose from.
  • Application: Select the appropriate one from among various typical applications
  • Vessel height/Measuring range: The vessel height or, in the case of applications not inside a vessel, the range in which the measured product moves (measuring range) is entered here.

Min./Max. adjustment

Distance measuring devices determine the distance to the medium surface, not the actual filling level in a container. In order to indicate the filling level, the measured distance must be assigned to the height of the medium as a percentage value. This calibration is then used to calculate the filling level.


Linearisation is necessary for all tanks where the tank volume does not increase linearly with the level, for example, in a horizontal round tank. The linearisation curve indicates the relationship between the percentage filling level and the container volume.

The following linearisation curves are available:

  • Linear, horizontal round tank, spherical tank
  • Flow devices: Palmer-Bowlus Flume, Venturi flume, trapezoidal weir, rectangular spillway, V-notch, triangular spillway

A linearisation assistant supports the calculation of complex tank geometries. 


If the volume is not to be displayed in percent but, for example, in litres or kilograms, an additional “scaling” is required.


Current output

The current output of a sensor is used to transfer the measured values to an evaluation system, e.g. to a PLC, a process control system, a measured value display or a controller.
In the case of a sensor in two-wire design, the sensor supply and the measured value transmission are carried out via a common two-wire cable. 


The menu language, the displayed measured variable and the appearance of the measured value are selected in the “Display” window.

Setup and commissioning

Saving instrument data

VEGA offers the option of managing the data locally on an end device or saving it in myVEGA via a personal account. Saving in myVEGA provides the advantage that the data is available to the user on all end devices and at any time via the VEGA website.


The “Create backup” function makes it possible to export the current DTM instance data to a file (the backup).

This file is used for data backup and can later be imported into a DTM of the same type to restore the instrument data.


Instrument documentation or the results of an instrument test can be conveniently created as a PDF file – flexibly via any operating device. The data is managed in the area “Documentation.”

Instrument memory

The measured value memory in the instrument saves the measured values over a certain period of time. It can also be read out from the instrument at a later time.

The event memory saves all events that have occurred in the sensor, such as error messages or parameter changes that have been made. These events can be read out from the sensor at any time with date and time stamp, providing a good overview of the instrument status. 


Service recording

Using the “Service recording” function, the DTM generates a complete set of diagnostic and analysis files – basically a record of measured values and echo curves.

The files are suitable for individual archiving and use in an external viewer. They are also helpful when support from a VEGA service technician is needed.

(1) A backup of all instrument data can be created via PACTware/DTM as well as the VEGA Tools app. 

(2) The backup files and documents are first saved locally on the device.

(3) Anyone who is logged into myVEGA on the respective end device can easily send the backup data to myVEGA.
