1715 Redundant I/O System in SIL 2 Safety Applications
Chapter 6
• Using ControlLogix controllers in SIL 2 Applications Safety Reference
Manual, publication
for detailed requirements for
installing, programming, and operating a SIL 2 ControlLogix-based safety
system.
• For specifications and certifications relating to a 1715 Redundant I/O
system, refer to the 1715 Redundant I/O System Technical Specifications,
publicatio
.
These 1715 devices can be included in a SIL 2 system.
See the latest certifications for software and firmware a
See the TÜV website at
for SIL 2 certification listings.
All I/O modules include line monitoring capability. We recommend that line
monitoring be used for safety-related I/O. Safety-related I/O refers to an
annunciator being available to an input or output attached to a field device. For
energize-to-action (normally de-energized) I/O, you must enable line
monitoring.
