Seamless high-speed integration to PROFIBUS PA
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 can integrate ComBricks into their PROFINET network via Osiris, allowing them to monitor everything from one single cross-platform.
The Anybus PROFIBUS PA link/coupler module enables seamless high-speed integration to PROFIBUS PA. It powers the attached PA devices and fully emulates them as DP devices on the backplane. Adjusted bus parameters are not required and therefore suitable for all DCS and PLC systems, even running on 12 Mbps.
The combined internal ProfiTrace and oscilloscope make this product extremely useful for remote maintenance over Ethernet. Jitter, noise, DC, DC voltage, bar graph and oscilloscope, it is all there and easy to access. The free CommDTM allows access to asset management tools over Ethernet.
ComBricks can carry 9 PA links and a RS 485 or Fibre Optic module. It can also be a customised mix of PA modules with other communication modules. The PA link provides a 500 mA current on a customisable bus voltage. The integrated PA termination is automatically activated when the module works as a power coupler. It is switched off in the monitoring mode.
It does not require configuration and operates the same way as regular ComBricks repeaters. In the web server, the behaviour on the PA side can be set, like retries (default 5) and the watchdog (default 3 seconds). This product can directly replace 3rd party Non-Ex PA couplers/links and can be used as a monitor behind existing 3rd party Non-Ex PA couplers.
