3.2.1 Description
The programmable fieldbus controller 750-806 (short: PFC) combines the
LON interface connection with that of a programmable logic control (PLC).
The application program is created with WAGO-I/O-PRO 32 in accordance
with IEC 61131-3.
According to the IEC 61131-3 programming, data processing occurs locally in
the PFC. The link results created in this manner can be put out directly to the
actuators or transmitted to the higher ranking control system via the bus.
The data is transmitted with network variables.
