Introduction

Non-redundant IO configurations can be used in systems with a non-redundant Controller as well as in systems with redundant Controller. Fully non-redundant systems are typically used for safety applications where redundancy is part of the process. In a Safety Manager setup with a redundant Controller, and (partly) nonredundant IO, both Control Processors alternately assume responsibility for the non-redundant IO interfaces. This ensures both Control Processors can always access the IO interfaces correctly. Safety Manager configurations with a redundant Controller and non-redundant IO interfaces are typically used for safety critical applications with increased demands for system availability, for example because of redundancy in plant equipment. The combination of redundant and non-redundant IO interfaces is extremely powerful. Process safeguarding functions requiring optimal availability are controlled through the redundant IO interfaces, and less demanding safety functions through the non-redundant IO interfaces.
