5.1.1 Pulse Input Type

The Pulse Input Type can be assigned by making the selection from the Input Type drop down menu. The user can select either Water or Gas as the Input Type.

Figure 9: Pulse Input Type

5.1.2 Pulse Input Name

The pulse input name is a user input field that can be as long as 19 characters. User may enter a combination of characters and numeric operators to enter the pulse input name. The first character of the pulse input name has to start with an alphabet or underscore (_). It cannot be a number or numerical operator to begin with. The input name can include the at (@) sign, the underscore (_) and the hyphen/dash (-) sign. The input Name field cannot be empty. The field does not allow white space ( ) or dots (.).

If the user tries to save the pulse configuration with no entry in the pulse input name field, the system responds with a message “Invalid User Input” and highlights the missing information field.

5.1.3 Start Pulse Count

The Start Pulse Count is a user input field that can be as long as 10 characters. The range is 0 to 4294967295. The user can only enter numbers in this field.

If the user tries to save the pulse configuration with no entry in the start pulse count field, the system responds with a message “Invalid User Input” and highlights the missing information. If the user inputs the values in range and clicks save, the system provides a message “Object Settings saved successfully”. If the user enters an out of range value, the system responds with a message “Invalid User Input”.

Scale Type Data type Scale ValuesScaled Pulse Input Values in Units

Float REAL Whole numbers and Decimal numbers with 4 significant digits after decimal point

Present value x Scale

Integer INTEGER Whole numbers only

Table 2: Scale Type Selection

5.1.5 Scale

The Scale field is a user input field which allows the user to enter a scale value (multiplier) for the pulse counts to match the water/gas consumption. This value needs to match the pulse count frequency as set up by the external entity (such as the Utility service provider or the entity authorized to make changes on behalf of the Utility) for the water or gas inputs.

The user can enter up to 12 characters in the scale field. Scale field has a range of -999999 to 999999. The user can only enter numbers, dot (.) sign and the hyphen/dash (-) sign. Alphabets or other special characters are not allowed. If the user enters a decimal number as a scale, the user can only enter up to 4 numbers after the decimal point.

If the user provides no entry and tries to save, the system responds with an “Invalid User Input” message. If the user provides an entry out of range, the system responds with an “Invalid User Input”. If the user enters an in-range value and clicks save, the system responds with “Object Settings Saved successfully”.

5.1.4 Scale Type

The Scale Type is a user input field with a drop down menu to select the scale operation for the pulse input value.



Figure 11: Units When Input Type is Water

5.1.6 Unit

The Unit field is automatically populated to the correct input type after the input type selection is complete. When the user selects, Water, as the input type, the Unit selection field is modified to show the units for Water Consumption Measurement (Gallon, Cubic Feet, Liters, and Cubic Meters). By default Gallon is the unit for water pulse inputs if no further selection is made.

When the user makes the selection for either input type and clicks on save, the system responds with a message “Object Settings saved successfully”.

5.2 Pulse Configuration Help

Clicking on the question mark “?” opens the pulse configuration help page. This page lists the definition of each of the user input fields in the pulse configuration page.

Figure 12: Units When Input Type is Gas

Figure 13: Pulse Configuration Help


6. Realtime

Water and gas consumption and information related to the water and gas pulse inputs from the PLC have been marked with PLC as prefix, to differentiate those values from the on-board water and gas pulse inputs. Further the Pulse Input0 and Pulse Input1 count values provide a summary of the Pulse Counts from the on-board pulse inputs.

If the user makes changes on the Pulse Input Configuration such as the Input name, Start Pulse count and the Units, the corresponding values are reflected on the realtime page.

In this case, the Pulse Input0 configuration values are modified to input Gas as the Pulse input0 input, with a special name and the start pulse count. The realtime page reflects the same changes for the Pulse Input0 in the summary section.

Figure 14: Realtime Page

Figure 15: Pulse Input Configuration for Pulse Input0

Figure 16: Realtime Summary page reflecting the Pulse Input0 changes

6.1 Scaled Pulse Inputs

The Scaled Pulse Input values include the label that is used to name the pulse inputs, the physical values of the scaled pulse inputs and the configured units. The scaled pulse input value is the product of the actual pulse count and the scale.

The range for the pulse counts is 0 to 4294967295. The range of the scale is -999999 to 999999. This means that the range of the scaled pulse count is -4294963000032705 to 4294963000032705.

Any increase in the pulse input value after attaining the max value will result to 0. Hence if the pulse count is 4294967295 and the pulse count increments it will overflow and the result will be 0. In this case the scaled pulse input will restart from 0.

By default, the pole selection is One Pole. The configuration settings are same as the one for BACnet IP.

7.2.2.1 BACnet Object Map Configuration Help

The user can access the BACnet Object Map Configuration Help page by clicking on the question mark “?” navigation link on the top right corner of the page. This opens another window showing the help information for the corresponding page.

7.2.3 Object Configuration

Clicking on the Object Configuration navigation link allows the user to navigate to the Object Configuration page.

Figure 64: Navigation to the Object Configuration in BACnet MSTP



By default the Analog Input Object Configuration page is displayed for object configuration. All the parameters and the information for the analog input, binary input, notification class and accumulator configuration is similar to the BACnet IP section. The only difference is in the Device Object Configuration.

7.2.3.1 Device Object Configuration

Clicking on the Device tab shows the device configuration page. This page is similar to the BACnet IP Settings except there is a new parameter added for BACnet MSTP called Max Masters.

Figure 66: Default Device Configuration Page



7.2.3.1.1 Max Masters

The Max Masters field allows the user to configure the maximum masters device in the present MSTP network. The Max Masters field has a range of 1 – 127.

If the user does not enter a value in the Max Masters field and tries to save, the system responds with an error message “Invalid User Input”. If the user enters an in range value and clicks save, the system responds with a message “Device saved successfully”. If the user enters an out of range value in the Max Masters field and tries to save, the system responds with an error message “Invalid User Input”.

7.2.3.2 Object Configuration Help

Clicking on the question mark (?) navigation link opens the Object Configuration Help page. This page lists the ranges and objectives of each of the parameter in the Object Configuration page.
