Profibus DP to PA Coupler(Converter)

Profibus DP to PA Coupler (Converter)

Profibus DP/PA coupler is conversion device between fieldbus PROFIBUS DP and PROFIBUS PA, which can convert and transfer data between this device.The module can be used independently, but also can be used with the fieldbus distributor with redundant structure of ring network on ROFIBUS PA segment

Shows the different methods for connecting the modules, and the optical ranges of port

Transmission rate of Profibus DP/PA Coupler

The coupler support the transmission speeds (transmission rates) defined in the EN 50170 standard:45.45Kbps,93.75Kbps,187.5Kbps,500 Kbps.The transmission rate is set automatically as soon as the receives a frame. The setting or adjustment is dependent on the transmission rate..

Segment monitoring at the RS 485 port

Each receiver monitors the RS 485 bus segment connected to it for faulty frames or continuously busy networks. If faulty frames are received by the receiver, or if the network is busy for longer than the maximum permitted send time, forwarding of the received signals is blocked until frames can be received again correctly
