FAST-Bi-1K5 – User’s Manual

an embedded Linux OS, that supervises all processes as communication, diagnostics
and local interface handling.
Remote communication is guaranteed by means of an Ethernet 10/100/1000
Mbit autosensing socket, present on the front panel of the PS. The power supply can be
also monitored and controlled via a navigation switch and a graphic high resolution
color display featuring user-friendly menus.
In addition to the standard Ethernet interface, it is possible to communicate with
the PS using the SFP-ports on the front panel. This interface allows the communication
using a proprietary packet structure with an update rate up to 100 kHz. These ports are
directly connected to the FPGA logic, so that the packet is elaborated directly by the
hardware logic.
This approach bypasses the software stratification that manages the packet. The
computational time is shorter and deterministic, leading to a high update rate of the
setpoint, and gaining flexibility and excellent rates for the digital control of the power
supply.
