Zero Pressure Accumulation (ZPA) via AS-Interface

Bihl+Wiedemann offers the possibility to implement a simple and cost-effective ZPA solution via AS-Interface without PLC programming effort and independent of the control and drive solutions used in the system. The ZPA logic for this runs in the ASi-5/ASi-3 fieldbus gateways, which are currently available for many common fieldbuses, and can be activated via a license (Art. No. BW4921). The easy to understand and comfortable configuration and parameterization is done via the software suites ASi Control Tools360 and ASIMON360.
