Hello Mazen; Most of your answer is spot on correct, but I must point out that Profibus PA does not use RS-485 to exchange data. It uses MBP (Manchester coded, bus powered) protocol, under specs for the FISCO model which are the same as used by Foudation Fieldbus. This why a DP/PA coupler (or DP/PA link) is required to communicate with PA instruments fromthe Profibus-DP network. You will find more information and links in the following discussion: /tf/WW/en/Posts/66310 Hope this helps, Daniel Chartier |

New question published by baban is split to a separate thread with the subject Parameters required to connect a drive to plc. Best regards |
