5.3.2.1 Digital Inputs (Mixed Mode)

The following table lists the available digital input configuration options available. Descriptions and example diagrams are provided in the next subsection:

The table below shows the binary-weighted values for the 2-bit Digital Input (DIN) function.

5.3.2.1.1 Pulse Measurements

Pulse measurements include Digital Input (DIN), Frequency (RATE), Pulse Width (WIDTH), Duty Cycle (DUTY), and Up Counter/Totalizer (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). When the reset input is activated then the pulse input value is zeroed for all pulse measurement types.

12 | M 5 7 5 2

Page 13

The Digital Input (DIN) mode reports the binary value on the DIN pulse input pins. Note the DIN

Frequency (RATE) = Total Count/second if > 100 counts/second

Frequency (RATE) = 1/pulse period if frequency < 100 counts/second

inputs replace the functionality of the Pulse and Reset 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.

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 below for details.

The Duty Cycle (DUTY) setting measures the percentage of time a pulse is active (high) over the total period of the signal. The duty cycle measurement allows reading the input from PWM control signals.

5.3.3 Discrete Input/Output (DIO)

The Omega Link SP-014 features 2 configurable discrete I/O pins; DIO_0 and DIO_1. 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 DIOs to utilize the outputs (ON/OFF, PWM, SERVO).

16 | M 5 7 5 2

Page 17

The Discrete I/O input shares the output circuitry. The internal process drives the output control signal to turn

Figure 18: Digital/Discrete I/O circuitry

Figure 19: SYNC interface outputs tab

Figure 20: SYNC interface Digital_IO

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 VDC to the Input Bias signal and reads the level detected at the Input Sense. If 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 VDC.

5.3.3.1 Setting DIO as an Input

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

Figure 21: Advanced Scaling Example

The Omega Link SP-014 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.

The screenshot above shows an example application for advanced scaling with renamed 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.

Description

Active

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 22: SYNC interface SP-014 DIO_0 and DIO_1 set to Disable

Figure 23: SYNC interface Output Configuration

The SP-014 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 5.3.3 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.

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.

20 % Duty Cycle

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:

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.

Page 21

Example: For the percent of angular travel, if the pulse width range is set to a range of 1.0-2.0 msec, then an

Figure 27: Sensor output mapping configuration example

100% Angular Travel = 2.0 msec

50 Hz

Figure 26: SERVO output example

1.0 msec = 0°

1.5 msec = 90°

2.0 msec = 180°

100% Angular Travel = 2.0 msec

output of 50% of angular travel represents 1.5 msec or 90 degrees of travel.

5.4.2 Sensor Output Mapping

The SP-014 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 28: Sensor output mapping diagram

Figure 29: 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 the

22 | M 5 7 5 2

Page 23

output will be set to OFF.

Figure 30: 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, Below, Outside the Range, or Within the Range. 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 (in Seconds) 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.

23 | M 5 7 5 2

Page 24

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 an Omega Link Gateway

Refer to either the Wired or Wireless instructions to pair an Omega Link Smart Probe & Interface to an Omega Link Gateway. Before continuing to the pairing instructions, ensure the following prerequisites are met:

• Ensure that the Omega Link 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 Omega Link

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 Omega Link 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 Omega Link 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 Omega Link Gateway, the LED will stop blinking on both devices. Readings for the newly added device will then appear on the Omega Link Cloud or OEG interface.

6.2 Wired Pairing

Wired Smart Probes connected directly to an Omega Link 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 Omega Link Cloud account.

Figure 31: 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.

Sensor Reading

The following Appendix provides the registers and list index for the Omega Link SP-014 Process Monitoring Smart Probe. This information is intended to aid users who will be making configurations and adjustments to their Omega Link SP-014 Process Monitoring 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.

7.1 Sensor Interface

Each enumerated Sensor has a Descriptor Base address location and a Sensor IPSO / Configuration structure address location based on the sensor mix selected.

7.1.1 Sensor Values

** The Pulse Delay and Up/Down counter are not available in the Mixed Mode configuration.

Sensors use float values which represent the measured value in the indicated units of measure.

Each sensor has a name. The default names for the outputs are created based on the value being measured. The default names may be overwritten, such as Room_Temp or Oven_Temp. Names are restricted to 16 characters.

The Sensor names are retained until a factory reset occurs. It is strongly recommended that:

1) Spaces within the name should be replaced with the ‘_’ character.

2) All sensor names on a particular device are unique – if duplicate functions are supported append a ‘_x’ string, where x represents the instance. For example, Temperature_1 and Temperature_2 could be used if 2 temperature devices are present.

7.2 Process Interface

The Process Input interface provides single-ended voltage and current loop inputs. The Sensor Configuration and Sensor Device fields may be written to provide control of the overall function of the channel and the signal types used.

Outputs share a common structure which consists of 3 fields mapped to a 16-bit unsigned integer, accessible in the Smart Sensor register map.

Refer to the specific output type for further information.

7.5.1 Scaling Minimum / Maximum Values

When Input Mapping is used the user may specify the input signal range through the Input Minimum and Input Maximum parameters. There is one pair of registers for each of the 4 possible outputs.

When either the Low Scale or High Scale value changes, an internal calculation is performed to calculate the linear transformation to be applied to the sensor reading.

7.5.2 Output Values

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%. (see Sensor Scaling).

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.

The Output names are retained until a factory reset occurs. It is strongly recommended that:

3) Spaces within the name should be replaced with the ‘_’ character.

4) 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.

7.6 Digital Output Configuration

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 nonconfigurable. The highlighted entries show typical default configurations.

7.6.1 Rate

PWM Rate

Name

Description

100 Hz

PWM signal has constant 100 Hertz frequency (10msec repetition rate) with 0 – 100 % duty cycle

10 Hz

PWM signal has constant 10 Hertz frequency (100msec repetition rate) with 0 – 100 % duty cycle

1 Hz

PWM signal has constant 1 Hertz frequency (1-second repetition rate) with 0 – 100 % duty cycle

0.1 Hz

PWM signal has constant 0.1 Hertz frequency (10second repetition rate) with 0 – 100 % duty cycle

PWM Rate

Name

Description

100 Hz

PWM signal has constant 100 Hertz frequency (10 msec repetition rate)

50 Hz

PWM signal has constant 50 Hertz frequency (20 msec repetition rate)

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

7.6.1.1 PWM Rate

The SP-014 supports the following PWM frequencies:

7.6.1.2 SERVO Rate

Smart Sensor probes support the following SERVO frequencies:

7.6.2 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.

7.6.3 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 a high impedance when active. When set to 0 (Active Low), the output will be low impedance to ground (~ 0.0 volts) when active. The Factory reset value is 0 (Active Low).

7.6.4 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.

7.6.5 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.
