1-4.1. Main Components
Following is a short description of the CFN PLUS main sub units (see Figure 1-3 and 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 back up,
along with 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 trough 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.
