1-3.7. System Workflow - Example
The following scenario illustrates an operational workflow for self-service at the Home Base
Station:
1-3.7.1. Refueling Scenario with FuelPoint PLUS
A motorist stops for fuel at the station. His authorization device for the fueling transaction is a
vehicle identification unit (FuelPoint PLUS) mounted in his car. The client lifts the nozzle and
inserts it in the car fuel inlet.
The FuelPoint PLUS information is automatically read and sent to the Site Controller (CFN
PLUS) for authentication and approval. Upon approval, the fueling transaction starts; when the
refueling is completed, the motorist replaces the nozzle back to the pump. At the end of the
process the transaction data is kept internally and transferred to the FHO for future billing.

1-4.1. Main Components
Following is a short description of the CFN PLUS main sub units (see
Figure 1-4
)
Orpak Controller Unit (OrCU)
Orpak Controller Unit (OrCU) is a complete forecourt controller
with its own embedded operating system. The unit consists of an
embedded hardware platform with a solid-state Flash hard disk,
Real Time Clock (RTC) with backup, and surge suppressors for
transient and noise immunity.
OrCU features two separate and isolated networks (TCP/IP over
Ethernet). One network links the CFN PLUS system components.
The second network is intended for external remote
communication (Head Office, 3
rd
party systems). This network is protected by SSL security. OrCU
includes a built-in server for Web access through an Internet browser (Explorer).
8-Port CommVerter
The 8-Port CommVerter consists of a communication board for
all CFN PLUS electronic units and for the peripheral equipment
interface.
The CommVerter includes two MPI-C cards for interface to the
mechanical pumps, an Ethernet Switch, RS/485 ports and one
RS/232 port. For electronic pump, a different interface card is
installed. See Chapter 3 for more details.
The CommVerter communicates with the Site Controller (OrCU) via a LAN (Ethernet) link.
