The Basissegmentkoppler by Pepperl + Fuchs is the successor of SK1 and SK2, a Profibus PA segment transparent to Profibus DP. With it, the Profibus PA devices appear as DP devices in the control system and can be configured and diagnosed there without additional tools. This transparency creates the base segment coupler entirely without own configuration. This simplicity enables efficient extraction of big data to optimize process management.
At the same time, the transmission rate and timing of the two bus systems are decoupled from each other. Communication with the control technology benefits from instantaneous responses of all subscribers in the Profibus PA segment at a transmission rate of up to 1,5 Mbps to Profibus DP.
The base segment coupler from the Field Connex series supports a high segment number per cabinet with only 20 mm housing width and very low power dissipation. The high packing density minimizes requirements for enclosed space.
Test taps enable the connection of mobile diagnostic devices for the physical layer, such as the Field Connex fieldbus diagnostic handheld. The connection is made without tools and without changing the installation. A plus, because the review is done without further intervention "as built" and the documentation is generated automatically. In combination with the high-power trunk, an intrinsically safe power supply of the instrumentation for a large number of terminals is possible, even if they are connected via long cable runs.
