Safety Manager basic architectures
Safety Manager can be configured for a number of architectures, each with its
own characteristics and typical Safety Instrumented Functions. Table 2 on page 9
provides an overview of the available architectures.

Dual Modular Redundant (DMR) architecture
Typical applications of a DMR architecture are:
• Burner Management System
• Batch processing
• Machine protection
The Dual Modular Redundant (DMR) architecture provides 1oo2 voting in a
non-redundant system. The DMR architecture with 1oo2 voting is based on
dual-processor technology, and is characterized by a high level of self tests,
diagnostics and fault tolerance.
