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 1756-RM001 .

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 1, 2000
• IEC 61511
Approval requirements are based on the standards current at the time of
certification. See Appendix E , 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.
