Install the AADvance System Chapter 5
System Security Serial networks are closed and local and have limited protocol functionality, so
they are immune to any external attack apart from local deliberate sabotage.
The AADvance system, however, with its workstations and DCS interfaces,
uses Ethernet networks which are frequently part of a larger corporate network
and can expose the system to accidental or malicious infection or attack.
These steps help prevent such issues:
• Network and workstation security must be used when installing and
setting up the system. As a minimum set up the following security
measures:
• AADvance must not be on a network with open unsecured access to
the Internet.
• The Firewall must be active on the Workstation, preventing access to
the relevant Ethernet ports on each communication interface. Anti-
virus software must be installed and be kept updated.
• The workstation must be password protected. If the workstation is a
laptop, it must be kept locked when not in use.
• If the workstation uses a hardware license USB dongle it must be kept
secure, without it the workstation will not run.
• The application must be password protected.
• Removable media, such as USB storage devices and CDs, must be
virus checked before use in the system.
Connecting Field Wiring Connect the field wiring to the screw terminal blocks on the termination
assemblies.
Use conductor wire with a cross section of 16 AWG. The stripping length
should be 6mm (1/4 in.) and a conductor temperature rating of 85 ºC. Apply a
tightening torque of 0.5 Nm (0.37 ft. lb.) to the terminal screws.
IMPORTANT Firewalls have been known to change the operation of the AADvance
