1 Introducing the PSS 5000
1 Introducing the PSS 5000
Description of the PSS
5000
The PSS 5000 enables you to control and monitor forecourt devices and inte-
grate a commercial Point-Of-Sale (POS) system (built for dry-stock sales) in
a petrol station environment, or to automate an unmanned site that does not
have a POS.
The PSS 5000 offers generic interfaces to the various types of forecourt devic-
es and their associated business logic. And with its modular design, the PSS
5000 can be tailored to almost any existing or new petrol station fore-
court/POS system. The modular concept also gives scalability. When changes
to a forecourt occur, then the PSS 5000 system adapts readily by the addition
or change of modules.
The PSS 5000 also offers unprecedented connectivity, including TCP/IP (via
both Ethernet or serial interface) as well as web server access for remote mon-
itoring, remote control and diagnostics of the forecourt devices and their oper-
ation. Using these features, it is possible to monitor stock levels remotely and
enable easy generation of wet stock reports and optimize distribution. It is also
possible to gather information and make diagnostics on the equipment remote-
ly, which saves on traveling costs and makes regular, planned maintenance
easier – reducing downtime and keeping maintenance costs to a minimum.
The diversity of the equipment types on the forecourt, the protocols they use
and their software versions require (sometimes rather complex) real-time con-
trol of the serial communication and a fast response to minimize customers’
frustrations and impatience. This is often difficult to achieve with the operat-
ing systems used by POS systems, but the PSS 5000 is built to handle such re-
quirements.
PSS 5000 generally provides the functionality and interfaces needed to inte-
grate Point-Of-Sale solutions for supermarkets or shops into a petrol station
environment. This enables fast time-to-market for POS suppliers, who may
not have the necessary resources for these special tasks.

Overview of PSS 5000
applications
How a PSS 5000 is integrated into a petrol station forecourt and some of the
necessary considerations are described in the following topics:
•‘2.1 Basic Scenarios for the PSS 5000’ on page 5
•‘2.2 Application Solutions’ on page 7
•‘2.3 Features of the PSS 5000’ on page 8
2.1 Basic Scenarios for the PSS 5000
Situations for the PSS
5000
The PSS 5000 is a versatile tool that enables you to control many types of op-
erations taking place on the forecourt. The basic processes are covered by the
simple scenarios listed below:
• Attended, stand-alone system
• Unattended, stand-alone system
• Attended, integrated with a POS system
Attended, stand-alone A simple example of an attended, stand-alone system where the PSS 5000 pro-
vides wet stock control is shown below:
Note: The term stand-alone is used when a POS is not present in the system.
In this scenario, the PSS 5000 is used to provide transaction data to the Tank
Gauge System (TGS) so it can verify that all the wet stock movements are le-
gitimate.
The functionality of the attended, stand-alone site can be extended when a
head office application, such as Site Info, is introduced. This enables price
changes and similar services to be implemented remotely from the head office.

2 PSS 5000 Applications
Unattended, stand-alone A simple example of an unattended, stand-alone system for unattended self-
service is shown below:
Note: The term stand-alone is used when a POS is not present in the system.
In this scenario, the PSS 5000 is used to control the fuel pump and authoriza-
tion is controlled via a 3rd party payment solution for cards and/or bank notes.
Attended, with POS A simple example of an attended site, with 2 POS connections, is shown be-
low:
In this scenario, the PSS 5000 is used to control the fuel pumps and connect to
the Point-Of-Sale (POS) terminals. Payments for the transactions take place
via the POS terminals.

2 PSS 5000 Applications
Vehicle Tagging, either
attended or unattended
A simple example of an attended site that uses vehicle tagging is shown below:
In this scenario, the vehicle is identified using a vehicle inlet tag, which is read
by the nozzle reader. When a valid tag is presented, the PSS 5000 is able to
authorize the dispenser to start. If the connection between the vehicle tag and
nozzle reader is broken, then the dispenser stops the fuelling until the two are
reconnected. Payments for the transactions take place via the POS terminals.
2.2 Application Solutions
Combining the basic
scenarios
By combining the basic scenarios, it is possible to provide a solution for the
individual sites. The illustration below shows a combination of all the basic
scenarios, which better represents the set up of a retail petrol station forecourt:
In this scenario, the PSS 5000 controls the operations of the forecourt pumps,
price poles and payment terminals, and provides a generic interface to the
Tank Gauge System for a readout of inventory data and deliveries. The PSS
5000 also ensures that any price changes are shown correctly on both the
pumps and price poles.
Business hosts and service organizations are able to take advantage of the net-
work connection to the PSS 5000. They are able to monitor the status of the
sites, gathering diagnostics and stock movements. This helps them to perform
planned maintenance tasks, optimize wet stock deliveries, and upload new
software, which can provide new features or improve some of the current op-
erations.

Changes to the forecourt
environment
The modularity of the PSS 5000, with its hardware interface modules and as-
sociated application software, makes it easy for the PSS 5000 to match any
changes made to the forecourt devices. By simply changing the modules to
match the devices on the forecourt and updating the application software, the
PSS 5000 is able to move forward as the site grows and changes. Because the
PSS 5000 with its standardized interface to the POS is situated between the
forecourt devices and the POS, then these device additions/changes rarely re-
quire changes to the POS.
2.3 Features of the PSS 5000
