The Layer N SP-013 Digital Interface Smart Probe provides an easy way to integrate digital pulse inputs into the Layer
N Ecosystem. The SP-013 accepts digital pulse inputs through its M12 5-pin connector and Layer N Smart Interfaces
through its M12 8-pin connector. The optional M12.8-T-SPLIT Sensor Splitter can be used to access the Discrete I/O
pins on the M12 8-pin connector. The optional M12.5-S-M-FM and M12.8-S-M-FM mating connectors can be utilized
to easily connect wire leads to the SP-013 or sensor splitter. The SP-013 may be configured to monitor the on/off
state of the input signals, the pulse rate/ duty cycle of the primary input, or the pulse delay between the two signals.
The pulse totalizing function supports both standard counting and up/down counting. A mixed-mode configuration
option allows for the measurement of one digital pulse input and one process input which may be independently
configured as a 0-24 mA, 0-1.0 V
The Layer N SP-013 features 2 configurable discrete I/O pins. These can be used for a myriad of applications including

5.3.1.1 Pulse Measurements
Pulse measurements include Digital Input (DIN), Frequency (RATE), Pulse Width (WIDTH), Duty Cycle (DUTY),
Phase Delay Between Pulse Inputs (DELAY), Up Counter/Totalizer (COUNT), and Up/Down Counter/Totalizer
(UP/DOWN COUNT). All measurements are derived from signal transitions and an internal 32.768 kHz time
reference. The pulse input signal is read on the Pulse A input (pin 2) and the reset input signal is read on the
Reset input (pin 5). The third input on pin 4 changes its functionality depending on the pulse measurement
type and can be Enable, Direction, or Pulse. When the reset input is activated then the pulse input value is
zeroed for all pulse measurement types. When the third input pin is configured as an enable input and is
deactivated then the pulse input value is zeroed. Unless otherwise stated, the third input pin defaults to
Enable functionality which must be set HIGH to allow measurement.
The Digital Input (DIN) mode reports the binary value on the DIN pulse input pins. Note the DIN inputs
replace the functionality of the Pulse, Reset, and Enable inputs.
Two measurement modes are used when measuring Frequency (RATE). If the measured frequency is
greater than 100 Hz the total number of pulses/second is used to determine the frequency. If the measured
frequency is less than 100 Hz the time between rising edges is used to calculate the frequency.
Count/second if > 100 counts/second
frequency < 100 counts/second
The Pulse Width (WIDTH) setting measures the active portion of a periodic signal in msec. The pulse input
may be configured to be active high or active low to measure the positive or negative portion of the pulse
width. See the Input Configuration Diagrams section for details.

edges of PULSE_A and PULSE_B
The Up Counter/Totalizer (COUNT) mode counts the number of rising edges while the Enable input is active
until the Reset input is activated. The Enable Input (Pin 4) acts as a Stop/Start for the Up Counter when
pulled up to 3.3 V. If the Enable Input is Inactive, it will pause/stop the up counter until it is re-enabled. If
the Enable Input is Active, it will start the up-count. Activating the Reset input (Pin 5) will reset the counter
back to 0. The Reset and Enable inputs can be configured to be active high or active low by configuring the
Enable Input to Pull-Down (PD). See the Input Configuration Diagrams section for details.

The following table lists the available digital input configuration options available when in mixed mode.
Some options available in digital-only mode are not available in mixed mode. Descriptions and example
diagrams are provided starting in section 5.3.1.1 Pulse Measurements.
Important: Digital input signals (pulse inputs) must be referenced to ground when Mixed Mode is used.
Negative offsets at pulse inputs may cause interference and noisy/incorrect readings in
analog (mA/V) process input signals.
The table below shows the binary-weighted values for the 2-bit Digital Input (DIN) function in mixed
mode.
5.3.2.2 Process Inputs (Mixed Mode)
The following process input configuration options are available in mixed input mode: 4-20 mA current loop,
0-1.0 V voltage input, 0-2.0 V voltage input. Current loop readings are rounded to the nearest 0.1 mA and
voltage readings are rounded to the nearest 10 mV.
5.3.2.2.1 4-20 mA Device Connection
The Current Loop interface measures the current into the selected input by converting it to a
voltage measurement across a fixed 49.9-ohm resistor.

5.3.3 Discrete Input/Output (DIO)
Figure 19: SYNC interface discrete I/O input configuration
Figure 20: Digital/Discrete I/O circuitry
The Layer N SP-013 features 2 configurable discrete I/O pins. These can be used for a myriad of applications
including driving relays, physical alarms, or sensing dry contacts like door switches. The user may configure
the polarity of the inputs (active HIGH or active LOW) or Disable the DIO to utilize the outputs (ON/OFF,
PWM, SERVO).
The Discrete I/O input shares the output circuitry. The internal process drives the output control signal to
turn on the output driver which will force the output low. When the state of the DIO input signal is to be
read the processor applies 3.3 V
to the Input Bias signal and reads the level detected at the Input Sense. If
DC
the output is inactive an external signal may be used to force the input level low. A diode protects external
positive voltages, allowing the output driver to activate loads greater than the internal 3.3 V
DC
.

Page 19
5.3.3.1 Setting DIO as an Input
Figure 21: SYNC interface outputs tab
Figure 22: SYNC interface Digital_IO
To use a DIO pin as an input, make sure it is set to Active Low (default) in the Output Tab in SYNC.
Then, in the Input Tab, select a Type from the drop-down which includes DIO. Each DIO pin has an internal
pull-up, but to save power, the internal pull-up is only active when the unit takes a reading.
5.3.4 Advanced Scaling Options
The Layer N SP-013 allows for advanced scaling options on process and pulse inputs only. The Advanced
Scaling checkbox can be selected to expand additional configuration options. A gain and/or offset can be
applied to the input reading and the displayed unit can be changed.
To apply a gain or offset to the input, expand the Scaling menu and ensure that Apply Scaling is checked.
There, the gain and offset values can be adjusted. Both positive and negative values may be entered as well
as decimal numbers. The equation for the scaled input value is given below.
The displayed units can be changed by entering a new value in the Unit field and clicking Apply Settings.
This field is limited to a maximum of 4 characters. Note that changing the Unit field does not change the
base unit type, only the display name. The Lock checkbox must be selected to use the user-defined Unit
field. Unchecking the Lock checkbox and clicking Apply Settings will revert the unit display back to the
default setting.

Figure 23: Advanced Scaling Example
The screenshot above shows an example application for advanced scaling with changed units. A fan tachometer
with a 500 Hz signal is connected to the Pulse Rate input. The fan outputs 2 pulses per revolution, so to convert
to rotations per minute (RPM) the reading must be divided by 2 which is accomplished by setting the Gain to
0.5. The units can then be renamed to RPM and will display as such.

5.4 Output Configuration
Option
Value
Description
LOW
When the output is inactive, it is in a high impedance state.
HIGH
When the output is active, it is in a high impedance state.
Figure 24: SYNC interface SP-013 DIO_0 and DIO_1 set to Disable
Figure 25: SYNC interface Output Configuration
The SP-013 offers two discrete outputs that share circuitry with the discrete inputs. If an output is to be used then
the corresponding input pin must be set to Disable. See section 5.3.1 Discrete Input/Output (DIO) for more
information.
There are three types of output options – On/Off, Pulse-Width Modulation (PWM), or Servo. See section 5.4.1 for
more information on each type.
Outputs may be configured as either Active High or Active Low. When configured as Active High the output conducts
normally and becomes high impedance when activated. When configured as Active Low the Open-Drain output is
high impedance normally and will conduct when activated.
Active
An output may be controlled in one of three ways – a scaled mapping to an input, an on/off control from an input
setpoint, or as an input alarm. Sections 5.4.2 through 5.4.4 describe these output control methods.

There are three types of output options – On/Off, Pulse-Width Modulation (PWM), or Servo. This section
describes these output options.
5.4.1.1 ON/OFF Output Type
The ON/OFF output mode switches the output to be a binary ON or OFF. Depending on if the output is
configured as Active Low or Active High, the ON/OFF mode can correspond to different polarities.
5.4.1.2 Pulse-Width Modulation (PWM) Output Type
Pulse-Width Modulation (PWM) controls the amount of power given to a device by cycling the on/off
phases of a digital signal. PWM consists of a duty cycle and frequency. The Duty Cycle measures the amount
of time a signal is in the ON state as a percentage. The frequency controls how fast the PWM cycle is
repeated. Users can select between the following settings:
Rate
Signal Type
5.4.1.3 SERVO Output Type
The SERVO output allows driving servo motors that control position. A Servo output is a special case of the
PWM output, where the ON time varies between 1.0 msec and 2.0 msec or between 0.5 msec and 2.5 msec,
with the lower bound representing 0 degrees and the upper bound representing 180 degrees of angular
travel. The typical non-critical frequency is 50 or 100 Hz. Servo outputs are always active high.
Rate
with a 100 Hz frequency and active HIGH
outputs. The duty cycle has been set to 20%.

Page 23
Example: For the percent of angular travel, if the pulse width range is set to a range of 1.0-2.0 msec, then
Figure 29: Sensor output mapping configuration example
100% Angular Travel = 2.0 msec
50 Hz
Figure 28: SERVO output example
1.0 msec = 0°
1.5 msec = 90°
2.0 msec = 180°
selecting 50% of angular travel represents 1.5 msec or 90 degrees of travel.
5.4.2 Sensor Output Mapping
The SP-013 allows mapping a scaled copy of any of the input values to any of the outputs. To set a mapped
output, it must not be associated with any alarm or ON/OFF control module. Two user-defined values,
Scaling Minimum and Scaling Maximum, define the sensor range that is mapped to the output. A Factory
Reset sets the Input Minimum to 0 and the Input Maximum to 100.
The scaling equations for direct and reverse output percentages are given below.
Example: The figures below and above display a PWM output direct-mapped to a Rate input. The minimum
expected input rate is 25 Hz and the maximum expected rate is 150 Hz. A value of 50 Hz read at the input is
then mapped to a PWM output with an 80% duty cycle.

5.4.3 ON/OFF Control Module
Figure 30: Sensor output mapping diagram
Figure 31: SYNC interface ON/OFF control module functions
To configure an ON/OFF control module on a device, first ensure that the desired output pin is not
associated with any input alarms and that it is set as No Mapping in the Output Mapping menu in the
Outputs tab. The ON/OFF control module can be used with any selected output type including ON/OFF,
PWM, and SERVO. When enabled in PWM mode, ON corresponds to 100% duty cycle. When enabled in
SERVO mode, ON corresponds to 100% angular travel.
In the Outputs Tab in SYNC click on the icon located to the right of the available outputs. Clicking the
icon will open the Define ON/OFF Control dialog box as seen below.
The Enable Control checkbox enables the ON/OFF control module. If this box is unchecked, the output will
be disabled but the module with all its settings will remain available to be enabled at a later time.
The Inputs dropdown lists the available input sources and will depend on how the device is configured in
the Inputs tab.
The Setpoint field sets the threshold for activating the ON/OFF control module. The unit of the Setpoint
field will be the same as the unit of the chosen Input.
The Control Actions dropdown has options for direct or reverse control. In direct mode, once the Setpoint
value is reached then the output will be set to ON. In reverse mode, once the Setpoint value is reached then
24 | M5751
Page 25
the output will be set to OFF.
Figure 32: SYNC alarm configuration interface
The DeadBand field together with the direct or reverse control action configures a deadband range around the
Setpoint where the ON/OFF control does not toggle. The unit of the DeadBand field will be the same as the unit
of the chosen Input.
• Example 1: the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with direct control
action. The output will activate if the input rises above 60 Hz. Conversely, the output will become
inactive if the input falls below 50 Hz.
• Example 2: the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with reverse
control action. The output will activate if the input falls below 40 Hz. Conversely, the output will become
inactive if the input rises above 50 Hz.
The Save button saves and applies the configurations settings to the ON/OFF control module. The Delete button
only appears for a previously saved ON/OFF control module and it removes the module and allows other output
types to be configured such as an alarm or mapping.
5.4.4 Setting an Alarm
Alarms are set by clicking the icon in SYNC on the desired input signal found in the Input Tab.
Configure the Condition that triggers the alarm by selecting an option from the drop down such as Above or
Below. The Threshold field(s) will change to display whatever is appropriate for the option chosen such as a High
Threshold for an Above condition or a Low Threshold for a Below condition. A Duration can be set for the trigger
as well where the condition must be met for a certain amount of time before the alarm flags.
Under the Action menu, the option to transmit or not transmit a notification can be set. The option to enable an
output can also be set. The output chosen must not be currently used in a sensor mapping or ON/OFF control
module. The data transmission interval may also be changed upon triggering an alarm, e.g. increate the rate of
transmission if an excessive value is detected.
The Recovery menu allows the option to clear the alarm after a certain Duration once the trigger condition is no
longer met. The transmission interval can also be reset to the normal system setting once the alarm is cleared.

To create a new alarm, click the plus icon and a new alarm will be added. To remove an alarm once it is
created, select the alarm in question on the left side of the alarm panel and click the delete icon .
6 Pairing a Sensing Device to a Layer N Gateway
Refer to either the Wired or Wireless instructions to pair a Layer N Smart Probe & Interface to a Layer N Gateway.
Before continuing to the pairing instructions, ensure the following prerequisites are met:
• Ensure that the Layer N Gateway has been properly setup, powered on, and in close physical proximity.
• (For Wired pairing) Ensure the user has access to a PC and the internal Gateway UI (refer to the Layer N Gateway
manual for instructions on how to access the internal Gateway UI).
6.1 Wireless Pairing
Pairing a wireless Smart Interface (IF-006) with probe attached is made easy with a one-button pairing system
between the IF-006 and the Layer N Gateway.
Step 1: When the Smart Probe and relevant accessories have been securely connected to the IF-006, push the
pairing button once on the IF-006. The LED status indicator will blink green indicating the device is in
Pairing Mode.
Step 2: Quickly push the pairing button on the Layer N Gateway. The LED on the Gateway will blink green indicating
the Gateway is in Pairing Mode.
When the IF-006 or Smart Sensor has been successfully paired to the Layer N Gateway, the LED will stop blinking on
both devices. Readings for the newly added device will then appear on the Layer Cloud or OEG interface.
6.2 Wired Pairing
Wired Smart Probes connected directly to a Layer N Gateway with an IF-001 cable or IF-002 will need to be added to
the Gateway Internal User Interface.
The Connected Devices tab is the default page set once you are signed in to the internal gateway UI. From here, you
can add devices to your gateway to have them appear in your Layer N Cloud account.
Figure 33: Gateway Internal User Interface
To add a device to your gateway from the internal gateway web UI, begin by clicking the button at the top
right of the web page. Fill out the Add Device menu with the parameters of the Smart Probe connection.

The following Appendix provides the registers and list index for the Layer N SP-013 Digital Input Smart Probe. This
information is intended to aid users who will be making configurations and adjustments to their Layer N SP-013 Digital
Input Smart Probe through the Command Line Interface or other custom interfaces.
Smart Probe devices share a common platform architecture that provides extensive monitoring and control
capabilities through a set of platform generic registers. These registers may be accessed using I2C based commands
directly to the Smart Probe devices or through a set of Modbus-based registers when using Omega Interface devices.
When powered on or after a device reset each Smart Sensor-based device will enumerate 1 or more sensor instances
which are described by the device-specific Sensor Descriptors which include configuration options, measurement type,
and units of measure for the corresponding sensor values. Additional sensor information is provided in sensor-specific
IPSO object descriptions which include extended measurement type, precision, and tracking of minimum/maximum
readings.
Each enumerated Sensor has a Descriptor Base address location and a Sensor IPSO /Configuration structure address
location based on the sensor mix selected.

Outputs use float values which represent the percentage of full scale. If the output is not mapped, the value
written (0 – 100%) is identical to the value that is read back. If the output is mapped, the scaling values are
used to transform the minimum input value to 0% and the maximum input value to 100%.
Output Name
7.4.3 Output Names
Each output has a name. The default names for the outputs are Output_0 through Output_3. The default
names may be overwritten, such as ‘Stack_Lite’ or ‘Control_Valve’. Names are restricted to 16 characters.
Output Name
The Output names are retained until a factory reset occurs. It is strongly recommended that:
1) Spaces within the name should be replaced with the ‘_’ character.
Size Description
Size Description
2) All output names on a particular device are unique – if duplicate functions are supported append a ‘_x’
string, where x represents the instance. For example, Stack_Lite_1 and Stack_Lite_2 could be used if 2
stack lights are being connected.

Description
PWM signal has constant 100 Hertz frequency (10 msec repetition
rate) with 0 – 100 % duty cycle
PWM signal has constant 10 Hertz frequency (100 msec repetition
rate) with 0 – 100 % duty cycle
PWM signal has constant 1 Hertz frequency (1-second repetition
rate) with 0 – 100 % duty cycle
PWM signal has constant 0.1 Hertz frequency (10-second
repetition rate) with 0 – 100 % duty cycle
Two output signals are available which may be configured for ON/OFF, PWM, or SERVO outputs through the Output
Configuration registers (0x0124 and 0x0126). The remaining outputs are assigned as phantom devices which are
non-configurable. The highlighted entries show typical default configurations.

The Rate determines the repetition rate, or frequency, of the Digital Output. For On/Off outputs the rate
field is ignored.

PWM signal has a constant 50 Hertz frequency (20 msec repetition
rate)
Smart Sensor probes support the following SERVO frequencies:
0 100 Hz
4 50 Hz
7.5.2 Output Type
Smart Sensor probes support NULL (0), ON/OFF (1), PWM (2), and SERVO (3) outputs. When set to NULL the
output signal will be left in a high impedance state. When set to ON/OFF the Rate and Servo Range controls
have no effect. When the SERVO type is selected the Duty-Cycle is restricted so the output signal is either
0.5 – 2.5 msec or 1.0 to 2.0 msec based on the Servo Range bit.
7.5.3 Active State
Smart Sensor digital outputs may be configured as Active HIGH or Active LOW. When set to 1 (Active High),
the output will be high impedance when active. When set to 0 (Active Low), the output will be low
impedance (~ 0.0 volts) when active. The Factory reset value is 0 (Low).
7.5.4 Mapping Enabled
The read-only Mapping Enabled bit indicates that the output may be optionally directly mapped to a sensor
input based on the Sensor Mapping field. If the Mapping Enabled bit is clear no mapping is supported, and
the Sensor Mapping field is ignored.
7.5.5 Sensor Mapping
The Sensor Mapping value may select ‘no mapping’ or of any Sensor. If no mapping is selected the output
may be directly controlled by writing a value from 0 – 100 % to the internal Output Value. If a Sensor is
selected and the hardware supports the mapping the output will track the selected sensor value, scaled by
the Input Minimum and Input Maximum values.
If Sensor Mapping is enabled for PWM outputs the scaling values are used such that a signal input at or
below the Scaling Low-value results in a 0% output and a signal input at or above the Scaling High-value
results in a 100% PWM duty cycle.
If Sensor Mapping is enabled for SERVO outputs the scaling values are used such that a signal input at or
below the Scaling Low-value results in a minimum (0.5 or 1.0 msec) pulse width and a signal input at or
above the Scaling High-value results in a maximum (2.0 or 2.5 msec) pulse width.
