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 2.0
• IEC 61511
Approval requirements are based on the standards current at the
time of certification. See
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.
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.
