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.

Overview 15

Safety Inputs

The controller has 16 local safety inputs, which support the features

described below.

• Input circuit diagnosis — Test pulse sources can be used to

monitor internal circuits, external devices, and external wiring.

• Input on- and off-delays — You can set input time filters of

0…126 ms in multiples of the controller cycle time. Setting input

on- and off-delays helps reduce the influence of chattering and

external noise.

• Dual Channel mode — You can set Dual Channel mode for pairs

of related local inputs. When Dual Channel mode is set, time

discrepancies in changes in data or input signals between two

paired, local inputs can be evaluated.

Safety Outputs

The controller has eight local safety outputs, which support the

features described below.

• Output circuit diagnosis — Test pulses can be used to diagnose

the controller’s internal circuits, external devices, and external

wiring.

• Overcurrent detection and protection — To protect the circuit,

an output is blocked when an overcurrent is detected.

• Dual Channel mode — Both of two paired outputs can be set

into a safety state without depending on the user program when

an error occurs in either of the two paired local outputs.

Test Pulse Sources

Four independent test outputs are normally used in combination with

safety inputs. They can also be set for use as standard signal output

terminals. The test pulse outputs support the following features.

• Overcurrent detection and protection — To protect the circuit,

an output is blocked when an overcurrent is detected.

• Current monitoring for muting lamp — Disconnection can be

detected for the T3 terminal only.

Communications

The controller can act as a DeviceNet safety master or slave, as a

DeviceNet standard slave, or as a standalone controller when

DeviceNet communications are disabled. A single controller can

Publication 1752-UM001A-EN-P - October 2006

16 Overview

function simultaneously as a safety master, safety slave, and standard

slave.

Explicit messages can be used to read controller status information.

Explicit messages set from the configuration software can be sent from

the user program.

The USB port can be used to program the SmartGuard controller and

to configure devices on the DeviceNet network. The SmartGuard

provides some limited pass-through capability from USB to DeviceNet,

for programming and configuration purposes. When used in

Standalone mode, the controller communicates with the configuration

software via USB communications.

Configuration and Programming

Use RSNetWorx for DeviceNet software to configure, program, and

monitor the status of the controller. With RSNetWorx for DeviceNet

software, you can configure the controller using the SmartGuard

controller’s USB port or via the DeviceNet network.

The logic editor is launched from within RSNetWorx for DeviceNet

software. Basic logic operations, such as AND and OR, and function

blocks, such as ESTOP and light curtain, are supported. A maximum

of 256 logic functions and function blocks can be used in a maximum

of 32 programming pages. You can password-protect both

configuration data and project files.

Status and Error Monitoring

The controller’s internal status information and I/O data can be

monitored online using RSNetWorx for DeviceNet software with either

a USB or DeviceNet network connection.

The LED indicators and alphanumeric display on the controller

provide status and error information. When the service switch on the

front of the controller is pressed, the alphanumeric display shows the

controller’s safety configuration signature two digits at a time for a

total of ten pairs of numbers.

Errors detected by the controller are recorded in an error history log,

along with the total operating time at the time the error was detected.

Overview 17

Safety Concept of the

Controller

The SmartGuard 600 controller is certified for use in safety

applications up to and including Safety Integrity Level (SIL) 3,

according to IEC 61508, and Category (CAT) 4, according to EN 954-1,

in which the de-energized state is the safety state. Safety application

requirements include evaluating the probability of failure rates (PFD

and PFH), system reaction-time calculations, and functional

verification tests that fulfill SIL 3 criteria. You must read, understand,

and fulfill these requirements prior to operating a SmartGuard 600

controller-based SIL 3 or CAT 4 safety system.

The controller uses the following mechanisms to support the integrity

of safety data.

• Safety network number (SNN) — A unique number that

identifies the safety network. Each DeviceNet sub-network that

contains safety nodes must have one unique SNN.

• Configuration signature — The combination of an ID number,

date, and time that uniquely identifies a specific configuration

for a safety device.

• Configuration lock (or safety-lock) — After the configuration

data has been downloaded and verified, you can lock the

controller’s configuration to prevent it from being modified.

• Password protection — The controller’s configuration can be

protected by the use of an optional password. If you set a

password, download, locking, unlocking, resetting, and

changing the status of the controller requires a password to

perform.

Additional Resources

Refer to the SmartGuard Controllers Safety Reference Manual,

publication 1752-RM001, for information on SIL 3 and CAT 4 safety

system requirements, including functional verification test intervals,

system reaction time, and PFD/PFH values.

ATTENTION

Environment and Enclosure

This equipment is intended for use in Pollution Degree 2 Industrial environment, in Overvoltage Category II

applications (as defined in IEC publication 60664-1), at altitudes up to 2000 m (6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.

Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility

in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as open type equipment. It must be mounted within an enclosure that is suitably

designed for those specific environmental conditions that will be present and appropriately designed to

prevent personal injury resulting from accessibility to live parts. The enclosure must have suitable

flame-retardant properties to prevent or minimize the spread of flame, complying with flame spread rating or

5VA, V2, V1, V0 (or equivalent) if non-metallic. The interior of the enclosure must be accessible only by the

use of a tool. Subsequent sections of this publication may contain additional information regarding specific

enclosure type ratings that are required to comply with certain product safety certifications.

In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, Alllen-Bradley publication 1770-4.1.
