Publication 1752-IN001C-EN-P - January 2009
Before You Begin
Before you install the controller, set its DeviceNet node address and communication
rate.
Set the Node Address
Use a small screwdriver to set the DeviceNet node address by using the two rotary
switches on the front panel of the controller. Use care not to scratch the switches.
Values from 00…63 are valid. The default setting is 63.
Follow these steps to set the node address.
1. Set the tens digit of the node address (decimal) by turning the left rotary
switch.
2. Set the ones digit by turning the right rotary switch.
3. To set the node address by using RSNetWorx for DeviceNet software, set the
rotary switches to a value from 64…99.
Setting the Communication Rate
The default communication rate for a DeviceNet network is 125 Kbps.
If you choose to use a different communication rate, the length of the trunkline and
types of cable determine which communication rates your application can support.
IMPORTANT Turn off power to the controller before setting the node address or communication rate
via the switches.
Do not change the switch settings while the power supply is on. The controller will detect
this as a change in the configuration and will switch to the ABORT mode.
IMPORTANT A node address duplication error will occur if the same node address is set for more than
one node.

and the 1752-L24BBBE controller has two latches on the bottom of the controller.
Grounding the SmartGuard 600 Controller
You must provide an acceptable grounding path for each device in your
application. Functionally ground the controller through its V0/G0 power
connection.
In addition, if you are using the 1752-L24BBBE controller, you should connect the
Ethernet ground terminal to an acceptable ground.
ATTENTION This product is grounded through the DIN rail to chassis ground. Use zinc plated
yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail
materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor
conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting
surface approximately every 200 mm (7.8 in.) and use end anchors appropriately.

Refer to the Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1, for additional information.
Connecting a Power Supply
Power for the controller is provided via an external 24V DC power source. The
output hold time must be 20 ms or longer.
To comply with the CE Low Voltage Directive (LVD), DeviceNet connections and
I/O must be powered by a DC source compliant with safety extra low voltage
(SELV) or protected extra low voltage (PELV).
To comply with UL restrictions, DeviceNet connections and I/O must be powered
by DC sources whose secondary circuits are isolated from the primary circuit by
double insulation or reinforced insulation. The DC power supply must satisfy the
requirements for Class 2 circuits or limited voltage/current circuits defined in
UL 508.
The SmartGuard controller has three V/G terminal pairs that require a power
connection. There are two V0/G0 pairs, but because they are internally connected,
you need to only connect one V0/G0 pair. You can use the other pair to distribute
power to other devices.

Alphanumeric Status Display
The controller’s alphanumeric display provides information about the module’s
status. Under normal operating conditions, the display shows the node address of
the module, 00…63 in decimal format. If the controller is operating in a standalone
configuration (not networked), the display shows ‘nd’. The display flashes when
the controller is self-testing, configuring, or in Idle mode. If a fault exists, the
display alternates between the error code and the node address where the error
occurred. If a fatal error has occurred, the display shows the error code only.
When the service switch is pressed, the display shows the controller’s
safety-configuration signature two digits at a time. The configuration signature can
also be viewed on the Safety tab of the Controller Properties dialog box in
RSNetWorx for DeviceNet software. You can use the configuration signature to
verify that the program and configuration of the controller has not been changed.
When the IP address display switch is pressed for 1 second or longer, the display
shows the EtherNet/IP address that is set. The error code ‘n4’ is displayed if an error
occurs in the EtherNet/IP configuration.
