Overview
The SpeedTalker-DN (XP) continuously monitors rotating shaft speed, providing measured RPM and
the status of up to four alarm functions over DeviceNet.
Measurable speed ranges from 0.0 to 6,553.5 RPM. Each configurable alarm function has on/off,
overspeed/underspeed, speed threshold, delay time and minimum on-time settings.
All configuration is handled over DeviceNet with parameter settings stored in non-volatile memory. An
electronic data sheet file (EDS) is provided to aid configuration.
Speed measurement and alarm status are provided over the Poll I/O connection. Alarm status is also
provided over the COS I/O connection for applications requiring sensor-initiated underspeed and/or
overspeed notification (e.g. ‘zero-speed’ sensing).

Operation
2.1
Indicator LEDs
The Network Status and Module Status indicators are located inside the enclosure (remove round cover
to view them). They are provided to aid setup, diagnostics and troubleshooting. Their operation is
standard DeviceNet.

Speed measurement
SpeedTalker-DN (XP) detects alternating magnetic pulses from a shaft-mounted rotating Pulser Disk
or Pulser Wrap and converts the pulse frequency into measured speed (RPM) units. The RPM value is
given in the Measured Speed attribute of the Speed object and is also part of the Assembly object’s Data
attribute (Poll I/O connection). See the Device Profile for details.
The Measured Speed is governed by two configuration parameters:
Target Pulses/Rev (PPR)
Set this to the pulses per revolution of the Pulser Disk/Wrap used.
Note that the Target PPR is one-half the number of Pulser Disk/Wrap magnets.
Minimum measurable speed
Sets the minimum shaft speed (RPM) below which the measured RPM will be zero. This is particularly
useful in slower speed applications to reduce the time taken to detect zero RPM.

2.3
Alarm functions
Four configurable alarm functions (Alarm 4...1) are provided for detecting underspeed or overspeed
conditions. Each may be used individually or in any combination with the others. All have identical
capabilities and each works independently of the others.
The states (Alarmed/Not-Alarmed) of the four alarm functions are given in the low four bits of the
Alarm Status attribute of the Alarm object and is part of the Assembly object’s Data attribute (Poll I/O
connection).
Alarm Status is also available over the COS I/O connection for applications requiring sensor-initiated
underspeed and/or overspeed notification. See the Device Profile for details.
The following three configuration parameters apply to all four alarm functions:
Alarm 4...1 ON/OFF
The low four bits of this parameter selectively turn the alarm functions ON/OFF.
Alarm 4...1 Over/Under
The low four bits of this parameter set alarm overspeed/underspeed functionality for the alarm functions.
When set for overspeed, a function becomes alarmed when measured speed is greater than the
Overspeed Alarmed trip-point and becomes not-alarmed when it is less than the Not-Alarmed trip-point.
When set for underspeed, a function becomes alarmed when measured speed is less than the Underspeed
Alarmed trip-point and becomes not-alarmed when it is greater than the Not-Alarmed trip-point.
Alarm threshold hysteresis
Works with each function’s Alarm Threshold and Over/Under setting to determine the RPM trip-point
for exiting the Alarmed state. It has no effect on the RPM trip-point for entering the Alarmed state.
Over/Underspeed Alarmed trip-point:
Alarm Threshold
Overspeed Not-Alarmed trip-point:
(1 - %Hysteresis/100) * Alarm Threshold
Underspeed Not-Alarmed trip-point:
(1 + %Hysteresis/100) * Alarm Threshold
Example
for %Hysteresis = 1%, Alarm Threshold = 100.0 RPM, Overspeed:
Alarmed trip-point = 100 RPM, Not-Alarmed trip-point = 99.0 RPM
Each alarm function has the following configuration parameters:
Alarm threshold
Sets the RPM trip-point for entering the Alarmed state. Also works with the Alarm threshold hysteresis
and the function’s Over/Under setting to determine the RPM trip-point for exiting the Alarmed state.
Over/Underspeed Alarmed trip-point:
Alarm Threshold
Overspeed Not-Alarmed trip-point:
(1 - %Hysteresis/100) * Alarm Threshold
Underspeed Not-Alarmed trip-point:
(1 + %Hysteresis/100) * Alarm Threshold
Alarm ON delay
Sets the time that measured speed must be continuously at alarm levels before the function enters
the Alarmed state. This setting is useful for avoiding nuisance alarms resulting from transient speed
excursions into alarm levels.
Alarm ON minimum time
Sets the minimum time a function stays Alarmed once it has entered the Alarmed state.

Setup
3.1
Mechanical installation
The SpeedTalker-DN (XP) may be mounted on rigid conduit or with the mounting bracket assembly
(provided).
The gap (A) between the sensing head and the Pulser Disk/Wrap must be 1/16 to 1/4 inch.
The center line of the magnets (B) must allign with the center of the sensing head as the Pulser Disk/
Wrap rotates.
After mounting, remove the round cover and pull network cable through the conduit port into the
enclosure.

Wiring, power-up and getting on-line
After mounting and pulling DeviceNet cable into the enclosure, remove the connector plug from
its socket and connect the color-coded DeviceNet cable wires to the corresponding connector
plug terminals.

Connector terminals and Indicator LEDs
Re-install the connector plug.
If the network is powered, the LEDs will sequence through a brief test:
Network Status OFF, Module Status GREEN-RED-GREEN, Network Status GREEN-REDOFF.
If there are no MAC ID or Baud Rate conflicts on the network, the Network Status LED should
then flash GREEN indicating the node is on-line but not connected.
Set MAC ID, Baud Rate (DeviceNet Commissioning Tool required)
Once on-line, scan the network to find the SpeedTalker-DN (XP). Once found, you may change
the MAC ID and/or Baud Rate. The factory defaults are MAC ID 63 and Baud Rate 125k.
MAC ID changes take effect immediately, initiating a reset sequence similar to that of power-on.
Baud Rate changes don’t take effect until SpeedTalker-DN (XP) power is cycled off/on.
Configure SpeedTalker parameters (DeviceNet Configuration Tool required)
Register the SpeedTalker-DN (XP) EDS file with your DeviceNet Configuration Tool. Your
DeviceNet Configuration Tool uses this file to create a user-friendly interface to the configuration
parameters.
Speed configuration parameters:
2.1
Target Pulses/Rev (PPR)
Enter the PPR for the Pulser Disk/Wrap used.
Note: The PPR is one-half the number of Pulser Disk/Wrap magnets.
2.2
Minimum measurable speed
Enter the minimum shaft speed (RPM) below which you want the measured RPM to be
zero.
Speed parameters may be changed in either order. Changes take effect immediately.
Alarm configuration parameters:
Set the configuration parameters for any/all desired Alarm functions.
Alarm parameters may be changed in any order. Changes take effect immediately.

Configure Scanner (DeviceNet Configuration Tool required)
Add the SpeedTalker to the Scanner’s scanlist:
Select the SpeedTalker-DN (XP) from the Scanner’s list of available devices and add it to the
scanlist.
Select and map the SpeedTalker Inputs:
2.1
Select the desired SpeedTalker-DN (XP) input (Poll or COS) from the Scanner’s list of
available inputs.
The Poll connection produces the Assembly Object’s data attribute value (Class ID = 4,
Instance = 101, Attribute = 3).
The COS connection produces the Alarm Object’s Alarm Status attribute value (Class ID
= 101, Instance = 1, Attribute = 16).
2.2
Map the selected input to the desired Scanner memory locations.
For the Poll connection, set the byte offset and bit length to map the desired Data
Component (Speed Value, Alarm Status or both) from the I/O Assembly. See 4.2 I/O
Data Format for details.
For Speed Value only, set the byte offset to 0 and bit length to 16.
For Alarm Status only, set the byte offset to 2 and bit length to 8.
For both, set the byte offset to 0 and bit length to 24.
