Abstract:  With the evolution of data communications in process control, network problems have taken on new importance to process engineers. The data connections from DCS and PLC systems to the plant network are vital to production, yet can be an invitation to problems. This award winning paper looks at several real-life network disasters and discusses strategies for avoiding them. Solutions, including the use of packet filter firewalls and VLANs (Virtual Local Area Networks), are discussed. A case history from a pulp and paper mill illustrates how a firewall/VLAN combination can be implemented to protect process systems from business system impacts.
