1715 Redundant I/O System in SIL 2 Safety
Applications
This chapter provides information on using 1715 I/O modules in a low demand
SIL CL (claim limit) 2 system, such as a ControlLogix®-based SIL 2 system. For
SIL 2 safety application requirements specific to installing, programming, and
operating a ControlLogix application, refer to the Using ControlLogix in SIL 2
Applications Safety Reference Manual, publication
.
SIL 2 Safety Application
Requirements
To use the 1715 Redundant I/O system in SIL 2 safety applications, you must
have revision 2.001 or later, of the adapter firmware, the latest Add-on Profiles,
and the 1715 SIL 2 Add-On Instructions.

IMPORTANT
The TÜV Rheinland Group has approved the 1715 Redundant I/O
System for use in safety-related applications up to and including
SIL 2 according to these standards:
• IEC 61508, edition 2.0
• IEC 61511
Approval requirements are based on the standards current at the
time of certification. See
, PFD and PFH Calculations
for a SIL 2 System.
ATTENTION:
Personnel responsible for the application of safety-related
programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in
using the system.
