Smart Gateway configuration

FieldLogic Hub allows you to customize the configuration of your Smart Gateway.

The Smart Gateway has four types of configurations:

Communication configurations: Choose how the Smart Gateway communicates in the FlexNet network.
Battery monitor configurations: Choose settings that affect the battery life.
Digital input alarms: Alarms triggered by a change in the state of an attached digital input.
Sensor alarms: Alarms triggered by readings from a sensor attached to a 4-20 mA analog input.

Table 1. Communication configurations
Name	Purpose	Options
Configuration name	Enter a clear, descriptive name for this product configuration.	Type the desired name into the text box.
Network Type	Choose the type of network the SmartPoint is installed into.	If the drop-down menu is enabled, use the menu to select the appropriate type of network.
Fixed-base Network Integration	Choose whether there are FlexNet electric meters and/or FlexNet Remote Transceivers in the network.	Check the boxes to enable the FlexNet electric meters, Remote Transceivers, or both. This configuration option affects the SNR, Sample Rate, Transmit Rate, and Transmit Mode. These settings will be automatically adjusted based on your selection, and displayed in a table below the check boxes.

Digital Input Alarm Label	If Digital Input Alarm Enabled is selected, allows you to select a label for the digital input alarm.	Use the drop-down menu to select one of the following options: Open Close On Off High Low Full Empty Normal Alarm
Digital Input Start Alarm	Choose how long the trigger condition must be present before the alarm triggers.	Use the drop-down menu to select one of the following options: Immediate 10 ms 250 ms 500 ms 1 sec 5 sec 1 min 10 min
Digital Input Stop Alarm	Choose how long the alarm is active after the alarm stop condition is reached.	Use the drop-down menu to select one of the following options: 1 min 1 hour 1 day

When setting up sensor configurations, pay attention to the sensor settling delay. The following diagram shows how various sensor settings determine how the Smart Gateway takes samples:

Settling delay. The maximum settling delay is 1500 ms.
Time between samples. The minimum time between samples is 1 ms, maximum is 5 ms.
Power off delay. The maximum power off delay is 1500 ms.
The sample readings are averaged, and that average is reported.
Sample count. In this example, the sample count is 4. The maximum sample count is 8.

Table 4. Smart Gateway Sensor configurations
Name	Purpose	Options
Configuration Name	Set a customized name for the sensor configuration.	Type the desired name into the text box.
Sensor measures	Choose what your attached sensor is measuring.	Use the drop-down menu to select one of the following options: Temperature. Units: Celsius, Fahrenheit. Pressure. Units: PSIG, PSIA, BarG, BarA. Level/Distance. Units: ft, in, m, mm. Weight: lbs, kg. pH. Units: SU. Conductivity. Units: mS/cm. Blue-Green Algae. Units: RFU, cells/mL. Chlorophyll. Units: RFU, ug/L. Dissolved Oxygen. Units: mg/L. Turbidity. Units: NTU. Total Chlorine. Units: mg/L. Free Chlorine. Units: mg/L. Hydrogen Sulfide. Units: PPM. Other/Unitless. Units: Value.
Units	Choose the desired units. This option affects the other available configuration options.	Use the drop-down menu to choose the desired units. Options will vary based on what the sensor measures.
Sensor settling delay	Choose how long the sensor will be powered on before a reading is taken.	Type the desired time into the text box, in milliseconds. Recommended default value: 1500 ms.
Sensor power off delay	Choose how long the sensor will be powered on after a reading is taken.	Type the desired time into the text box, in milliseconds. Default value: 0.0 ms.
Sensor sample count	Choose how many samples are taken per sampling. These samples are averaged to produce one reading.	Type the desired number of sample counts into the text box.
Time between samples	Choose the amount of time between samples.	Type the desired time into the text box, in milliseconds.
Precision	Choose the number of decimal places used in readings.	Use the up and down arrow buttons to select the desired number of decimal places.
Activation settings	Choose where mA values are set during activation.	Use the drop-down menu to choose one of the following options: Prompt for Field Calibration: Change the actual value being measured, and have the Smart Gateway read the corresponding mA values. Not used for water utilities. Prompt for mA values during Activation: During activation, use the factory calibration to tell the Smart Gateway the range of the sensor and how to scale the mA values. Set mA values in Hub: During configuration creation, use the factory calibration to tell the Smart Gateway the range of the sensor and how to scale the mA values.
4 ma (minimum value) reading	Choose the sensor reading that corresponds to a minimum value reading for the Smart Gateway.	Type the desired value into the text box. Units vary depending on what is being measured.
