A modulating input is a physical input. You can configure Modulating Input blocks and use them while creating application logic.
To add and configure a Modulating Input block:
While using a LonSpyder Controller, the following fields are displayed.
| Name | Description |
| Point Name | Type a name of the function block or use the default names provided by the tool. |
| Point Type | Modulating Input is the default selection. You can select Constant, Modulating Input, Binary Input or Software Input if you want to change the input type. |
| Type | Displays the list of sensors that can be connected. Select a sensor type.
|
| Data Category | Displays the unit of measurement for the Type. This is enabled when Custom Resistive or Custom Voltage is selected in the Type field. |
| Data Type | Displays the engineering unit based on the Data Category. |
| Input State | Use this to edit sensor characteristics. The Input State is editable only
when a custom sensor (Custom Resistive or Custom Voltage)
is selected in the Type field. You can enter values for:
|
| Sensor Limits | Click the Sensor Limits button to view and set the upper
and lower limits.
Sensor Readings Outside Limit

| OK | Saves the entered information and closes the dialog box. |
| Cancel | Closes the dialog box. Any information entered is lost. |
Note: For Spyder Micro models: PVL4024NS, PVL4022AS, PUL4024S and PUL1012S, if you select Pulse_Meter or Counter as the sensor type, a default pin UI1 is assigned. If the pin is not available, or is currently assigned to another point, the tool creates the point as an invalid point.
When the modulating input is configured to type Counter in a Spyder Lon Micro, Spyder Bacnet Micro, or Spyder Lon Relay, it reads the number of counts received in the last second. For example, if a 10Hz signal is connected to the input, the input reads 10 counts each second. Another example, suppose a 0.5Hz signal is connected to the input, the input reads a 0 in the 1st second, a 1 in the 2nd second, a 0 in the 3rd second, a 1 in the 4th second, and so on. The maximum frequency of the signal allowed is 15Hz that is, maximum counts per second that can be wired to the input is 15 per second. The user can connect this to the function block logic and accumulate counts.When the pulses stop coming in, the power gradually decreases and goes to 0 in about 11 minutes. The maximum measured rate is 54000 pulses per hour. The calculated output of a pulse meter input is in pulses per hour. You can connect this to the function block logic (multiply by scale factor) to compute power. For example, if the pulse meter is at 3600 pulses per hour and this is multiplied with a scale factor of 10 Watt-Hours/Pulse, the current power is 3600 x 10 = 36000 Watts or 36 KW.
Note: The modulating input types Counter and Pulse_Meter can be configured to be Normally Open or Normally Close. This reverses the TRUE/FALSE logic.
Note: You can configure Custom Sensor properties only if Data Type selected is Custom Sensor. On selecting Custom Sensor as Data Type, the Custom Sensor Configuration button appears. Click this button and specify the following:
Sensor Type
Specification Unit (The Data Type option you have selected decides the Specification Unit options that will be available)
Input and Output Values for points 1 through 10.
The lowest and highest Input values are displayed under Input State in the Input Low and Input High fields.
The lowest and highest Output values are displayed under Sensor Limits in the Low Limit and High Limit fields. Click Save to save the changes
While using a BacnetSpyder Controller, the following fields are displayed.
| Name | Description |
| Point Name | Enter a name of the function block or use the default names provided by the tool. |
| Point Type | Modulating Input is the default selection. You can select Constant, Modulating Input, Binary Input, Network Setpoint, or Network Input if you want to change the input type. |
| Type | Displays the list of sensors that can be connected. Select a sensor type. |
| Point Category | Displays the unit of measurement for the Type. This is enabled when Custom Resistive or Custom Voltage is selected in the Type field. |
| Unit | Displays the engineering unit based on the Point Category. |
| Input State | Use this to edit sensor characteristics. The Input State is editable only
when a custom sensor (Custom Resistive or Custom Voltage)
is selected in the Type field. You can enter values for:
|
| Sensor Limits | Click the Sensor Limits button to view and set the upper

|
| Advanced | Displays the Bacnet object details. Object Name, Object Type, Object Instance are the fields provided. Object Name is automatically provided by the tool and can be edited. Object Instance number can also be edited. Object Type is a read only field and cannot be edited. If the GPU option in the advanced dialog box is set to True, Send Heartbeat is enabled. |
| OK | Saves the entered information and closes the dialog box. |
| Cancel | Closes the dialog box. Any information entered is lost. |
Note: You can drag IOs on to the wiresheet even when all pins are used up. Honeywell Spyder allows IOs to be dropped but they are not assigned with a pin. Such IOs are termed as invalid IOs.
When a modulating input is deleted, if it had a valid IO pin assigned, the freed pin is automatically assigned to any invalid modulating input or an invalid binary input.
When a physical IO (Modulating input, Binary input, Modulating output, Binary output) with a valid IO pin is copied and pasted in the wiresheet, the resulting IO gets the same configuration as the source and a new available pin. If no free pin is available, the resulting IO becomes an invalid IO.
When an invalid physical IO (Modulating input, Binary input, Modulating output, Binary output) is copied and pasted in the wiresheet, the resulting IO gets the same configuration as the source and it is also an invalid IO.
When you copy and paste a modulating input of type standard and custom sensors on the wiresheet, the same configuration is retained. Even though an On Board Pressure Sensor can be configured, it is a consequence of the copy and paste action on the wiresheet.
The on-board pressure sensor is always assigned to the Universal Input # 0, in case where the model supports this fixed physical point, whether it is physically present or not.
Note: The number of On Board Pressure Sensors you can add are dependent on the Controller model selected. If you exceed the allowed limit of On Board Pressure Sensors in an application logic, you cannot configure the modulating inputs as On Board Pressure Sensor.
Example: To the LonSpyder II model PVL6436AS, if you add more than six modulating inputs in your logic, the seventh Modulating input you add is automatically configured as an On Board Pressure Sensor and is assigned to Pin0.
To add an Onboard Pressure Sensor:

| Modulating Input | Constant |

| Modulating Input | NCI |

| Modulating Input | Binary Input |

Note: When you copy and paste an On Board Pressure Sensor (modulating input) on the wiresheet such that the maximum allowed count for that model is exceeded, it is converted to a custom voltage sensor .
