Custom Scenarios

Introduction to Custom Scenarios functionality

To meet the diverse and evolving needs of our clients, we have developed the Custom Scenarios feature. This solution allows users to define specific conditions using customizable parameters to trigger events or control a device’s digital outputs. By connecting the device to peripherals like alarms, buzzers, or relays, this functionality can notify drivers or perform targeted actions seamlessly.

The feature enables the device to operate autonomously based on predefined conditions, eliminating the need for constant monitoring of device status or complex backend integrations. With Custom Scenarios, any data the device can read becomes a potential input for controlling digital outputs, providing flexibility and efficiency.

Figure 1. “Custom Scenarios” functionality logic

The Custom Scenarios functionality enables configuration of up to three independent scenarios, each with up to three unique triggers. Triggers are defined using data from various I/O elements, such as: Fuel Level, Engine RPM, Seatbelt Status, DTC Faults, Movement Status, Ignition State, GSM Signal Level, 1-Wire/Bluetooth sensor temperature and etc. Each trigger is configured with specific logic operands (e.g., "On Entrance," "On Exit"), threshold values (Low and High levels), and an activation delay timer, which specifies how long a value must remain within the defined range before the trigger is activated.

When all triggers of a scenario evaluate as true, the scenario becomes active. This can generate a record (if configured) and control the digital output (DOUT) by toggling it on or off based on the active conditions. Additionally, if configured for continuous operation, the DOUT remains active as long as the conditions are met.

Key features include:

• Support for dynamic trigger logic based on selected operands and conditions.
• Autonomous device operation, even in low-power or deep-sleep modes, provided compatible I/O sources are used.
• Adjustable ON/OFF durations or permanent output control, enabling versatile device behaviors such as blinking or continuous activation.
• Custom Scenarios operate independently from the I/O menu, with priority management ensuring that higher-priority scenarios take precedence in controlling the DOUT when multiple scenarios are configured.

Custom Scenarios functionality configuration

Below is a detailed explanation of configurable parameters for each scenario.

Parameter Name	Custom Scenario 1 (ID)	Custom Scenario 2 (ID)	Custom Scenario 3 (ID)	Min Value	Max Value	Default Value	Description
Output Control	19100	19130	19160	0	3	0	Specifies the DOUT controlled by the scenario. Options include None, DOUT1, DOUT2, and DOUT3.
Priority	19101	19131	19161	0	3	0	Sets the priority of the scenario. Options include None, Low, High, and Panic.
Permanent Output Control	19124	19154	19184	0	1	0	Enables continuous DOUT control as long as conditions are met.
DOUT ON Duration	19102	19132	19162	100 ms	65,000,000 ms	200 ms	Duration for which DOUT remains ON when the scenario is active.
DOUT OFF Duration	19103	19133	19163	0	65,000,000 ms	200 ms	Duration for which DOUT remains OFF. A value of 0 means the DOUT stays ON continuously.
Source #1	19105	19135	19165	Device-specific	Device-specific	N/A	The primary I/O source for the trigger. This source cannot be ignored.
Source #2	19110	19140	19170	Device-specific	Device-specific	Ignored	The secondary I/O source. This source can be ignored.
Source #3	19116	19146	19176	Device-specific	Device-specific	Ignored	The tertiary I/O source. This source can be ignored.
Operand	19106	19136	19166	0	6	0	Defines the condition logic for the trigger. Options include On Exit, On Entrance, On Both, On Hysteresis, On Change, On Delta Change, and Is.
Low Level	19107	19137	19167	Dynamic	Dynamic	0	Sets the lower threshold value for the source trigger.
High Level	19108	19138	19168	Dynamic	Dynamic	0	Sets the upper threshold value for the source trigger.
Activation Delay Timer	19109	19139	19169	0 s	65,535 s	0	Time in seconds the condition must remain true for activation.
Logic	19115	19145	19175	0	1	1	Determines trigger evaluation logic. Options include OR (any trigger activates the scenario) and AND (all triggers must be true to activate the scenario).

Configuration Process

1. **Define Output Control**:

  - Assign the DOUT (DOUT1, DOUT2, or DOUT3) to be controlled by the scenario.

2. **Configure Triggers**:

  - Select up to three I/O sources (e.g., ignition, fuel level, temperature).
  - Define operands to specify logic (e.g., "On Entrance," "Is").
  - Set Low and High threshold values for each source.
  - Adjust the Activation Delay Timer for precise control.

3. **Set Priority**:

  - Choose the priority level for the scenario. Higher-priority scenarios override lower-priority ones for the same DOUT.

4. **Adjust DOUT Control Settings**:

  - Configure DOUT ON/OFF durations or enable Permanent Output Control for continuous activation.

5. **Save Configuration**:

  - Verify all parameters and save the configuration. The device evaluates scenario conditions every second.

Example Use Cases

- **Scenario 1**: Control a relay when fuel level drops below 10%. - **Scenario 2**: Trigger a buzzer if RPM exceeds 3000 while ignition is ON. - **Scenario 3**: Activate an alarm when GSM signal strength drops below 20%.
