Hello Roeland; Not only is it mandatory to have an option board to use Profibus on your analyser, you must also decide whther that option board will open communications to Profibus-DP or Profibus-PA. Have a look at the following document; OXYMAT 6 - Interface PROFIBUS DP/PA https://support.industry.siemens.com/cs/fr/en/view/7618463 TheA5E00015899Exi optional module allows intrinsically safe coupling to PROFIBUS-PA. TheA5E00034504 optional module allows non-intrinsically safe coupling to PROFIBUS-PA. TheA5E00019145 optional module allows coupling to PROFIBUS-DP. If you need further information on the variants of Profibus, you can search here on the forum (use the Search Box at the top right of this page) or on Profibus.com/download. But the basic difference is this: - Profibus-DP is designed for fast master-slave cyclic exchanges. Once the parameters of the communications are established, you receive continuoulsy the same process data and diagnostics from the slave. -Profibus-PA is slower, designed to integrate instrumentation in the PLC; you can not only receive the process data from the instrument, but you can also configure, calibrate and parametrise it , using an add-on software known as PDM (search on the forum for more info). Hope this helps, Daniel Chartier |
