Using the 1715 I/O
Select the Mix of 1715 I/O
Required
1715 I/O simplifies the configuration choices for a ControlLogix® SIL 2 system.
All I/O modules in the 1715 family are approved for use up to SIL 2, but proper
firmware is required. The system can be configured with any combination of I/O
modules, either in simplex or duplex mode and the redundancy features are built
into the hardware so no cross wiring of outputs to inputs is needed any longer nor
is the requirement to have two separate I/O chassis for Fault Tolerance.
For hardware selection, refer Chapter 6 of
Redundant I/O System User Manual
Figure 5 - Typical Simplex Application
IMPORTANT
The 1715 uses dual adapters even with simplex I/O.
For SIL 2 safety applications, you must have the following:
• Firmware for the 1715-AENTR adapters, revision 2.001 or later
• Add-on Profile for the adapter, version 2.01.014 or later
• Add-on Profile for the I/O modules, version 3.01.014 or later
• Add-On Instructions when using a ControlLogix system, version 2.001 or
later
• A 1756-L7 ControlLogix controller
