In most situations, safety is best achieved by an inherently safe process design
whenever practicable. When this is not practicable, the residual risk shall be
identified and handled by one or more protective systems.
The overall safety requirements of a process are identified by carrying out hazard
and risk assessment, the identified safety requirements are allocated to safety
functions and related protection systems (protection layers). Depending on the
number of protection layers identified, and the risk reduction they provide, the need
for a Safety Instrumented System (SIS) may arise. For each identified safety
function the Safety Integrity Level (SIL) shall be identified.
The AC 800M HI is certified to handle safety functions with SIL2 and SIL3
requirements.
Important characteristics of the SIS are the response time during normal operation;
Demand Response Time (DRT), and the response time during internal faults; Fault
Detection and Reaction Time (FDRT) for single channel 1oo1D systems. For AC
800M HI this is the SIL2 configuration. These characteristics of the SIS relates to
the Process Safety Time (PST) of the process to be controlled. For definitions of
terms and abbreviations like DRT, FDRT and PST, see Terminology on page 28.
As the initiator and actuator response time varies for various devices, the SIS shall
be configured to guarantee a logic solver FDRT (see Figure 1 below) to meet the
process requirements according to the applicable industrial standards. In the 1oo2D
System structure (SIL3) first faults are controlled by the system architecture. This
means first faults are detected and reacted upon within the application interval time.
In the 1oo2D System Structure the FDRT is not used to comply with requirements
to detect faults within the Process Safety time.
