Future proofing your network to……keep up with bandwidth demand
One challenge of integrating both horizontally and vertically is the increased bandwidthrequirement.
One example, best in class companies already incorporate voice and video on their industrialnetworks adding to the bandwidth demand.
New Network designs and upgradesneed to provide the necessarybandwidth for those demands:
à 1/10 Gbit/s ports on plant switches

Future proofing your network by……using Hardware that allows changes
Today’s applications change more often than in the past. In fact interfaces typically change asthe network architectures evolve.
Modular switches allows quick andcost effective changes to interfaces(copper, fiber etc)
à Reducing Total Cost of Ownership

Wireless in Industry – A success factor
Wear & tearon materials
Challenges and Solutions
Lack ofMobility
Poorexpansion
options
Commissioning
Trailing Cables, Power Rail Booster or Slip rings are subject to Wear & Tear
àWireless LAN offers a solution free of Wear & Tear
Commissioning Time and Cabling especially is very expensive
àWireless LAN offers a cost-effective solution
Many hard-wired systems on the market offer poor expandability options
à Adding more nodes to a Wireless systems is simple
Cabled or Track-based solutions don’t offer the flexibility and mobility, demandingapplications call for today and therefore limit the design
àWireless LAN systems offer maximum flexibility and mobility

Things to consider when using Wireless
IWLAN from Siemens……reliable, rugged and secure
Don’t try to use Wireless for every application, use it for the right applications
Wireless requires planning, consider contacting experts that will help you gettingstarted
Even Safety can be implemented, but the more demanding the application, the moreimportant the planning and execution becomes
Site surveys are a normal preparation step in more complex applications

Main Trends Impacting the Vulnerability ofAutomation Plants
§ Horizontal and Vertical Integration at all network levels§ Connection of automation networks with IT-Networks
and Internet for remote maintenance§ Increased use of open standards and PC-based
systems
§ Possible Threats increased due to these trends:§ Access violation through unauthorized persons§ Espionage and manipulation of data§ Damages and data loss caused by malware
à A risk assessment can help to identify potentialrisks

Industrial SecurityThe Defense in Depth Concept
Plant security§ Access blocked for unauthorized persons§ Physical prevention of access to critical
components
Network security§ Controlled interfaces between office and plant
network e.g. via firewalls§ Further segmentation of plant network
System integrity§ Antivirus and whitelisting software§ Maintenance and update processes§ User authentication for plant or machine
operators§ Integrated access protection mechanisms in
automation components
Security solutions in an industrial context must take account of all protection levels
