Firmware
To use 1715 modules in a ControlLogix SIL 2 system, you must use firmware that
has been designed for SIL 2 use.
Duplex Configurations
For duplex configurations, a SIL 2 fault-tolerant architecture has dual-input, dual
adapter, and dual output modules. The input and output modules operate in
1oo2D (1 out of 2) under no fault conditions and degrade to 1oo1D (1 out of 1)
upon detection of the first fault in either module. The modules fail-safe if faults
occur on both modules. The adapters operate in 1oo2D under no-fault
conditions and degrade to 1oo1D upon detection of the first fault. A duplex
system could therefore be 1oo2D reverting to 1oo1D on the first detected fault
and reverting to fail-safe when both modules have a fault. Fail-safe is defined as
the ‘de-energized’ or ‘off ’ state. A Simplex Input or Output module is SIL 2
capable. Configuring them in a Duplex configuration adds availability but doesn't
add to the safety capability
