Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the
Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales
office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-
wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all
persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or
application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements
associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the
examples and diagrams.

How To Use This Manual
Read and understand this manual before using the described
products. Consult your Rockwell Automation representative if you
have any questions or comments. This manual describes how to use
modules.
About the Specifications
and Dimensions in This
Manual
Product specifications and accessories can change at any time based
on improvements and other reasons. Consult with your Rockwell
Automation representative to confirm actual specifications of
purchased product. Dimensions and weights are nominal and are not
for use for manufacturing purposes, even when tolerances are shown.
Terminology
Refer to the table for the meaning of common terms.
This Term Means
Bus off Indicates a status of very high error-count occurrence on a communication cable. A bus off error is detected when the
internal error counter counts more errors than the predetermined threshold value. (The error counter returns to zero
when the master is started or restarted.)
Connection Logical communication channel for communication between nodes. Connections are maintained and controlled
between masters and slaves.
CRTL Connection reaction time limit.
DeviceNet safety An implementation of a safety protocol on a standard DeviceNet network.
EDS Acronym for electronic data sheet, a template that RSNetWorx for DeviceNet software uses to display the
configuration parameters, I/O data profile, and connection-type support for a given DeviceNet safety module. These
are text files used by RSNetWorx for DeviceNet software to identify products and commission them on a network.
L- Output return common.
M Sinking output common channel, output switches to the common voltage.
MTBF Acronym for mean time between failure, the average time between failure occurrences.
ODVA Acronym for Open DeviceNet Vendor Association, a nonprofit association of vendors established for the promotion of
DeviceNet networks.
P Sourcing output channel, output switches to the plus voltage.
PFD Acronym for probability of failure on demand, the average probability of a system to fail to perform its design function
on demand.
PFH Acronym for probability of failure per hour, the probability of a system to have a dangerous failure occur per hour.
Proof test Periodic test performed to detect failures in a safety-related system so that, if necessary, the system can be restored
to an as-new condition or as close as practical to this condition.
S+ Output return 24V.
SNN Acronym for safety network number, which uniquely identifies a network across all networks in the safety system.
You are responsible for assigning a unique number for each safety network or safety sub-net within a system.
Standard Devices or portions of devices that do not participate in the safety function.
