Product Information

Product Description

Authorized North America Distributor Stamp

The ComBricks PROFIBUS PA segment coupler module enables seamless integration to PROFIBUS PA. The coupler powers the attached PA devices and forwards telegrams coming from the ComBricks backplane. With ProfiTrace OE and the oscilloscope, this product is extremely powerful for remote maintenance over Ethernet and the use of asset management tools. ComBricks comes with free CommDTM software!

The coupler module can be combined with other ComBricks modules for 3 primary applications:

1.Combined with a Type 3 Head station and used behind an existing coupler as a permanent monitoring tool
2. Combined with a Type 1 Head station and a PROFIBUS repeater card as a PROFIBUS DP/PA coupler
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.
  • PA monitor behind existing 3rd party Non-Ex PA couplers.
  • Very small dimensions.

The ComBricks backplane can handle 10 PA coupler modules or a mix of PA modules with other communication modules.

The integrated PA termination is automatically activated when the module works as a regular PA coupler. It is switched off in the monitoring mode.

Free 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 which 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 busmonitor and oscilloscope work simultaneously with the CommDTM.
