Preface
Introduction
The ControlLogix/1715 SIL 2 system uses Standard ControlLogix processor
modules along with 1715 I/O modules. A SIL 2 system is formed by one or more
controllers, I/O modules, their power sources, communications networks, and
workstations. This tips guide helps to give a quick start for using the
ControlLogix/1715 SIL 2 controller and systems.
There is usually some confusion between GuardLogix® and ControlLogix SIL 2
since GuardLogix can be used in a SIL 2 system and it is based on ControlLogix.
In this guide we refer to ControlLogix only, NOT the red safety GuardLogix
controller, and it uses only 1715 I/O.
ControlLogix SIL 2 can be used with 1756 or 1794 IO as well. 1756 and1794 IO
are covered in the ControlLogix SIL 2 Safety Reference Manual (1756-rm001)
and are not discussed here. Note if you are using 1715 IO instead of 1756 or 1794
IO then the information on those IO platforms in the information in the Safety
Reference Manual does not apply.
