An RS 485 PROFIBUS repeater module with an integrated quality oscilloscope for 12 Mbps with diagnostic LEDs and a redundancy feature

The Anybus ComBricks is the first PROFIBUS-based automation system that unites repeaters and permanent monitoring in a web browser. With an evolving industry using more mixed architecture networks, users are able to integrate ComBricks into their PROFINET network via Osiris, allowing them to monitor everything from one single cross-platform.

The Anybus SCOPE Repeater is a 1 Channel RS 485 PROFIBUS diagnostic repeater module with an integrated quality oscilloscope for 12 Mbps with diagnostic LEDs and redundancy feature. Bus connection is utilised by screw terminals and additional DB9 connectors.

The repeater channel and the integrated oscilloscope are directly connected with the ProfiTrace OE core in the 1B/1C Head Station. Scope images and bus monitor data are directly available on the web server.

The advanced 12 Mbps core of the repeater module can be cascaded unlimitedly and has increased RS 485 strength. The data traffic is constantly monitored for glitches which are digitally filtered out. It has on-board switchable termination and is able to drive 31 devices.

Cascading units

With standard busparameters:

At baudrate       Normal mode[units]

19.2 kbps                                         7

45.45 kbps                                       42

93.75 kbps                                       7

187.5 kbps                                       7

500 kbps                                          17

1.5 Mbps                                          23

3 Mbps                                             19

6 Mbps                                             16

12 Mbps                                           15


Formula to calculate number of cascading units with adjusted Tslot :

Cascading units = (Tslot – maxTsdr) / (2 × Tdata_delay_time)

Tdata_delay_time  is described in protocol specifications on previous page.

Example 1.5 Mbps, normal mode:

Cascading units = (300-150) / (2×3.2) = 23
