8 Rockwell Automation Publication 440R-UM012E-EN-P - November 2018
Preface
Terminology
Publication AG-7.1 contains a glossary of terms and abbreviations that are
used by Rockwell Automation to describe industrial automation systems.
Specific terms and abbreviations that are used in this manual include:
• Normally Closed (N.C.) - An electrical contact whose normal state (for
example, no pressure or electrical potential applied) is in the closed
position.
• Normally Open (N.O.) - An electrical contact whose normal state (for
example, no pressure or electrical potential applied) is in the open
position.
• Reaction Time - Describes the time between the true states of one input
to the ON state of the output.
• Recovery Time - Describes the time that is required for the input to be
in the LO state before returning to the HI state.
• Response Time - Describes the time between the trigger of one input to
the OFF state of the output.
• Output Signal Switching Device (OSSD) - Typically a pair of solid-
state signals that are pulled up to the DC source supply. The signals are
tested for short circuits to the DC power supply, short circuits to the
DC common and shorts circuits between the two signals.
• Single Wire Safety (SWS) - A unique, safety-rated signal that is sent
over one wire to indicate a safety status. The SWS can be used in
Category 4, Performance Level e, per ISO 13849-1 and safety integrity
level (SIL) 3, per IEC 62061 and IEC 61508.
