Chapter 7 1715 Redundant I/O System in SIL 2 Safety Applications
See the latest certifications for software and firmware at
. See the TÜV website at
for SIL 2 certification listings.
All I/O modules include line monitoring capability. We recommend that you
use line monitoring for safety-related I/O. Safety-related I/O refers to an
annunciator being available to an input or output that is attached to a field
device. For energize-to-action (normally de-energized) I/O, you must enable
line monitoring.
Typical Configurations
The 1715 system supports single module configurations, where it is acceptable
to either stop the system or allow the signals corresponding to that module to
change to their default fail-safe state. It also supports fault-tolerant I/O
configurations where the system is required to continue operating in the event
of a fault.
Fault tolerant systems have redundant modules that let the system continue
operation in the presence of a fault. The system fails safe if another fault
occurs.
All configurations can be used for safety-related applications. Choose the
appropriate configurations that are based on the fault tolerance requirements
of your application.

For revision 3.001 and later, the 1715 I/O module firmware displayed is the revision that is installed on the I/O module.
For earlier revisions 1715 I/O module firmware is displayed as the same level of the firmware of the 1715-AENTR module
regardless of the actual firmware level in the 1715 I/O module.
