Diagnostics (control)
Overview display
Control display
Detail display
Support display
P&I oriented
Performance/ availability
Key process values (normal operation)
e.g. group control
Level 4 Functional aspects
• Topology-oriented and task-oriented plant hierarchy (level 1 - level 3)
• Significance of level 2, more displays, mainly used for monitoring but also for controlling
• Several detailed views on the same plant section, mainly used temporarily for start-up, diagnostics etc.

Effective alarm management with SIMATIC PCS 7 alarm system
Alarm management design supports operators when handling abnormal situations
Alarm management
• Alarm processing and filtering • Smart alarm hiding • Prioritized alarms depending on urgency
• Alarm-related help texts • Operator guidance (loop-in alarm) • Process oriented representation of alarms

Flexible Modular Redundancy ™
Flexible Redundancy at all levels • Scalable for different applications
(ESD, HIPPS, F&G etc.) • Controller redundancy for availability
.. not required for safety • Physical separation to combat
common cause • Flexibility to accommodate different
SIF architectures so … • Field device redundancy can be
designed to achieve safety and availability goals
• I/O redundancy independent of CPU
