Typical DeviceNet Configuration
A DeviceNet Network supports multiple Stack Light devices and allows them to
communicate with other network devices (up to 64).
The DeviceNet Stack Light operates on the network as a slave device. It does not initiate
communications except for a duplicate node address check on power-up. The master writes
data to, and receives data back from, the DeviceNet Stack Light.
The following DeviceNet configuration shows a variety of products operating as slaves to a
PLC-5 controller with a 1771-SDN DeviceNet Scanner Module.

Installing the Modules
The stack light modules are installed to the base by placing a sealing o-ring between the base
and the module, lining up the arrow on the bottom of the module with the line on the top of
the prior module or base, and twisting the top module clockwise to lock them into place.
IMPORTANT
For more information on different modules, refer to the Signal Solutions Selection Guide
(Publication 855-SG001*-EN-P) or the Industrial Controls Catalog.
The DeviceNet Base is compatible with all 24V DC 855T modules.
Connection to the Network
Wire the DeviceNet Stack Light to an operating network. If the device is an 855T-DSxxxx,
the wires should be connected to a terminal block. If the device is an 855T-DMxxxx or
855T-DLxxxx, it will be connected with the quick disconnect connector. The device is fully
powered by the network, therefore it is important that the device is located near a power
supply.
For more information on system installation, refer to the DeviceNet Media Design Installation
Guide (Publication DNET-UM072*-EN-P).

4-2 Operations
The following tables give a brief explanation of the individual parameters and their uses:
Parameter 1 — Autobaud Enable
When enabled, the stack light automatically communicates at the network baud rate detected
at power-on. When disabled, the baud rate must be set correctly by the user during node
commissioning. This parameter’s setting takes effect after a module reset or at power-on.
Note: Only valid when rotary switch is set between 3…9. The default value is Enabled.
Table 4.B
Value Function Value Function
0 Enabled 1 Disabled
Parameter 2 — Off-to-On Delay
The Off-to-On delay determines the amount of time for which an input signal must be fully
present before the stack light updates the I/O. It is a means of filtering for noise on input
lines. The value must be set in units of microseconds. The default is set to 0 s to ensure
proper filtering on noisy lines, but it can be reduced depending on the application. (Not Used)

Parameter 3 — On-to-Off Delay
The On-to-Off delay determines the amount of time for which an input signal must be fully
absent before the stack light updates the I/O. It is a means of filtering for noise on input lines.
The value must be set in units of microseconds. The default is set to 0 s to ensure proper
filtering on noisy lines, but it can be reduced depending on the application. (Not Used)

Parameter 4 — Fault State
This parameter tells the stack light what to do with the output in the case of a fault state. If
“Go to Fault Value” is selected, the device refers to the Fault Value parameter to determine
the state. If “Hold Last State” is selected, the output stays in the last state. The default value is
0 — Go to Fault Value.

Value Function Value Function
0 Go to Fault Value 1 Hold Last State
Parameter 5 — Idle State
This parameter tells the stack light what to do with the output in the case of an idle state (an
I/O connection exists, but the master is in program mode or idle state). If “Go to Idle Value”
is selected, the device refers to the Output Idle Value parameter to determine the state. If
“Hold Last State” is selected, the output stays in the last state. The default value is 0 — Go to
Idle Value.

Communication Faulted Request - long protocol message.
Troubleshooting
The 855T Control Tower Stack Light goes through a power-up sequence when power is
cycled. It first goes through an internal memory check; if it passes this stage each of the
outputs is powered for 200 ms. If this does not occur, there is an internal fault with the device
or the modules are not connected properly. Check the modules for a good connection and
cycle power. If fault still exists, return the 855T Control Tower Stack Light for repair.
After power-up the device tries to connect to the network. The data rate is selected through a
rotary switch; if the data rate is incorrect the device will fault. Disconnect the device, change
the switch setting, and reapply power. If the data rate is unknown, Autobaud may be selected
and the device will select the correct data rate. (Note that this option can only be used with a
running network. It cannot be used for node commissioning.) (Autobaud will not work if it is
disabled through the parameter setup.)
Publication 855T-UM001C-EN-P May 2005
Troubleshooting and Maintenance 5-3
Once the baud rate is set, the device issues a duplicate MAC ID check. If there is a duplicate
node on the network, the 855T Control Tower Stack Light will fault. Disconnect the device,
change the node address to an available one, and reapply power.
If the stack light or network resets when multiple outputs are turned on, it is likely due to
inadequate network power supply. This device has a high power consumption when used
with incandescent modules. Refer to the DeviceNet Media Design Installation Guide,
Publication DNET-UM072*-EN-P to make sure the power supply sizing and placement are
correct.
Bulb Burnout
Bulb Burnout is reflected in the Status Byte returned from the device. This feature only works
with incandescent modules or incandescent/sound combination modules. The current draw
of other module types is too low to sense correctly.
For burnout detection to work properly, the module type parameter must be configured by
the user. This can be done with the RSNetWorx for DeviceNet Software. If a module is
misconfigured, it may be reflected as a burnout in the Status Byte.
In order to clear the Status Byte, change the bulb and cycle power. If this does not clear the
fault, verify correct configuration of the module type parameter.

Off-Line Node Recovery
Chapter Objectives
Table 6.A
Section Page Section Page
Overview 6-1 Sample Recovery 6-2
Overview
The Bulletin 855T Stack Light is equipped with a function known as Off-Line Node
Recovery. Off-Line Node Recovery is used mainly to commission a device on a network.
When a new product is put on the network, it is at a default address of Node 63. If multiple
units are placed on a network without first using node commissioning to change the node
address a duplicate MAC ID error occurs. This means that more than one device is located at
the same node address and only one of them is allowed online. Off-Line Node Recovery now
allows you to recover the faulted devices and change the node address. This is a powerful tool
because multiple nodes can be put on the network on installation and recovered one at a time
without having to continually reset the network. The following section will walk through a
sample recovery.
Note: If the MAC ID is set through the rotary switches, Off-Line Node Recovery will not be
able to recover the faulted device because it cannot change the node address.
