Potential Security Problems with OPC OPC Server OPC Client OPC Client OPC Client OPC Client OPC Server Plant LAN DeltaV Control Network

What Is Xi?
Like OPC,
Xi is a client server for data exchange between level 2 (control system level) and Level 3 (business / MES level)
Xi supports the same servers OPC DA, HDA and AE
Unlike OPC,
XI is a secure means for real-time and historical data transfer between DeltaV and 3 rd party systems and applications
Firewall friendly using HTTP/HTTPS
Uses secure Web services (via WCF - Microsoft Windows Communication Foundation)
Easy to implement interface

Increased Communication Robustness Xi Server Xi Client Xi Client Xi Client Xi Client Xi Server Plant LAN DeltaV Control Network Jan‘10 If client communications are lost, the Xi interface will retain the current state of the connection and allow the client to re-establish communications without losing configuration Firewall

Unified Interface for All Xi Server Data Xi Server - DA Interface Xi Server - HDA Interface Xi Server - A&E Interface Xi Client Xi Client Xi Client Xi Client Xi Server Plant LAN DeltaV Control Network Jan‘10 Xi client application can access Xi Data Access, Xi Alarms & Events and Xi Historical Data Access data via one Xi interface Firewall

OPC Servers Remain Available OPC DA Server OPC Client OPC Client OPC Client OPC HDA Server OPC A&E Server OPC Client OPC Server Plant LAN DeltaV Control Network DeltaV OPC Servers will remain to provide a migration path and to maintain legacy OPC client communications

Xi and OPC Clients and Servers in the Same System OPC Client OPC Server Plant LAN DeltaV Control Network Jan‘10 Xi Client Xi Client DeltaV Xi and OPC clients and servers can be used simultaneously in the same system with 3 rd party Xi and OPC clients and servers Xi Server OPC Server OPC Client Xi Client OPC Client Xi Client
