The ComBricks PROFIBUS DP/PA coupler is the latest in innovations for the ComBricks family. This 21st century coupler leapfrogs the competition in features and footprint and enables seamless integration to PROFIBUS PA. The DP/PA coupler powers the attached PA devices and forwards telegrams coming from the ComBricks backplane. With the optional ProfiTrace OE and the oscilloscope, this doubles as an extremely powerful tool for remote maintenance over Ethernet. The coupler also enables the use of asset management tools with its free CommDTM software!

The DP/PA coupler module comes in two configurations:

  1. 1. Combined with a Type 1 Head station and a PROFIBUS repeater card as a PROFIBUS DP/PA coupler
  2. 2. Combined with a Type 3 Head station and a PROFIBUS repeater card as a PROFIBUS DP/PA coupler with monitoring

The PA segment coupler does not require configuration and operates the same way as regular ComBricks repeaters for PROFIBUS DP. The coupler has several advantages when compared to other existing couplers on the market:

  • Transparent on 9.6 kbps up to 1.5 Mbps.
  • Customizable PA voltage.
  • Can directly replace 3rd party Non-Ex PA couplers.
  • Very small footprint.

The DP/PA coupler can be expanded by adding additional PA and DP modules. The ComBricks backplane can any combination of 10 PA or DP modules. Just snap in the additional modules as needed!

The integrated PA termination is automatically activated.

CommDTM for ComBricks

The free ComBricks CommDTM provides FDT 1.2 based asset management tools such as FieldCare and PACTware a powerful Ethernet pass through to access PROFIBUS DP and PA devices that are connected behind ComBricks repeater modules.

The internal DP-V1 class 2 masters in the ComBricks Head Station are able to drive 2 out of 4 networks divided over the repeater modules. When a network connection is closed, the user can enter another network. The 2 active networks are managed by 1 or 2 PC Ethernet connections.

The CommDTM provides the same auto baudrate detection facilities as ProfiCaptain. It detects all busparameters before it goes online.

All ComBricks functions, like the integrated ProfiTrace bus monitor and oscilloscope work simultaneously with the CommDTM.
