Preface
Definitions Publication AG-7.1 contains a glossary of terms and abbreviations used by
Rockwell Automation to describe industrial automation systems. Below is a list of
specific terms and abbreviations used in this manual.
• CCW – The Connected Components Workbench. This is a software
package that allows the user to configure a CR30, program a Micro800®
controller and configure a PanelView™ HMI.
• CR30 – Is the Cat. No. 440R-CR30-22BBB software configurable safety
relay, described in this user manual.
• HI – Logic state of being ON.
• LO – Logic state of being OFF.
• Logic Block – On the CCW grid, a logic block resides in any of the four
columns. A logic block is either: 1) a Safety Monitoring Function, 2) Logic
Level A, 3) Logic Level B, or 4) Safety Output Function.
• Logic Level A (LLA) – This column is used to perform logic processes on
a number of inputs to create a desired output state.
• Logic Level B (LLB) - This column is used to perform logic processes on a
number of inputs to create a desired output state.
• N.C. (Normally Closed) – An electrical contact whose normal state (i.e.,
no pressure or electrical potential applied) is in the closed position.
• N.O. (Normally Open) – An electrical contact whose normal state (i.e.,
no pressure or electrical potential applied) is in the open position.
• OSSD (Output Signal Switching Device) – This is typically a pair of
solid state signals that are pulled up to the DC source supply. The signals
are usually tested for short circuits to the DC power supply, short circuits
to the DC common and shorts circuits between the two signals.
• Reaction Time - Describes the time between the true states of one input
to the ON state of the output.
• Recovery Time - Describes the time 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.
• Safety Function – This describes the complete sensing of the action (e.g.
open a safety gate) to execution the final output device (e.g. turning off a
pair of contactors).
• Safety Monitoring Function (SMF) – This is the input block on the
Connected Components Workbench for the CR30.
• Safety Output Function (SOF) – This is the output block on the
Connected Components Workbench for the CR30.
• Single Wire Safety (SWS) – This is a unique, safety rated signal 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.
