Process bus
Devices with a process bus interface allow direct communication with SICAM HV mod-
ules. The process bus interface is equipped with an Ethernet module.
PROFIBUS
PROcess FIeld BUS, the German process and field bus standard, as specified in the
standard EN 50170, Volume 2, PROFIBUS. It defines the functional, electrical, and
mechanical properties for a bit-serial field bus.
PROFIBUS address
Within a PROFIBUS network a unique PROFIBUS address has to be assigned to
