Intelligent linking devices

As the AC 800F possesses the high-speed connec

tion of both PROFIBUS (PROFIBUS DP) and FOUN

DATION Fieldbus (FF-HSE), the slower buses of the

two fieldbus technologies (PROFIBUS PA and FF-H1)

can be connected using intelligent linking devices.

These devices allow to connect several slow buses

to one fast bus, with the advantage that a lot more

field devices can be connected to an AC 800F sta

tion than when the slow fieldbuses are connected directly.

LD 800P PRoFIbuS DP/PA Linking Device

LD 800P is needed to connect PROFIBUS DP to

PROFIBUS PA. The LD 800P Linking Device converts

the physical bus characteristics of the RS 485 inter

face for the PROFIBUS DP into PROFIBUS PA physi

cal bus characteristics according to IEC 61158- ,

enables connected PROFIBUS PA devices to be

supplied with power via the bus, and additionally

allows use in intrinisically safe areas.
