Rules Complete Examples

The concept of NETIO Conditions (PAB & WatchDog) & Rules is a set of prepared detections (Conditions) and Rules that act upon them. They are implemented directly in NETIO PDU devices.

CR01 - WatchDog (ping) to 1 IP address | default in FW 3.2.3

The WatchDog functionality is used to monitor connectivity to specified IP address (or URL) by sending PING request to it.

The ping in this example is sent every 60s and waits 5s for the device to respond. If the ping fails, Watchdog returns false and restarts (ACTION: 2 = SHORT OFF) device connected to first output. After restart, it waits 120 seconds and starts monitoring again. If the device does not respond, WatchDog remains in ERROR state until next successful ping.

{
  "conditions": {
    "WDT/CR01_WDT/FAIL": true
  },

    "OUTPUTS/1/ACTION": 2
  }
}

CR02 - Digital Inputs (Push button to Toggle Outputs 1 and 2) | default in FW 3.2.3

Rule is used for managing outputs in response to change of Digital Inputs (DI) state. Rule monitors state of first DI. When DI switches from OFF (0) to ON (1), Rule switches (toggles) Outputs 1 & 2 to their opposite states (ACTION 4 = TOGGLE).

Rule definition

Rule name: CR02_RULE

{
  "conditions": {
    "INPUTS/1/STATE": "on"
  },
  "actions": {
    "OUTPUTS/1/ACTION": 4,
    "OUTPUTS/2/ACTION": 4
  }
}

CR03 - Load Watchdog (Restart device if it's more than 2 minutes in IDLE mode) | default in FW 3.2.3

Rule monitors load (Watts) on Output 1. If the load is between 1-20W for at least 2 minutes, it restarts (ACTION 2 = SHORT OFF) the output. Example uses PAB (Power Analysis Block) functionality to determine if measured value (load in our case) lies in given range for a period of time. When it does, defined Rule triggers device restart.

PAB definition

PAB name: CR03_PAB

{
  "type": "RANGE",
  "source": "OUTPUTS/1/LOAD",
  "lowerBound": 1,
  "upperBound": 20,

}

Rule definition

Rule name: CR03_RULE

{
  "conditions": {
    "PAB/CR03_PAB/IN": true
  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}

CR04 - Load Watchdog with alarm to Cloud

Rule monitors load (Watts) on Output 1. If the load is between 1-20W for at least 30 minutes, it restarts (ACTION 2 = SHORT OFF) the output. In addition, it triggers an alarm in NETIO Cloud, which sends a notification to specified email address. This example needs a NETIO Cloud account with Premium version active for first output. There also has to be email notification enabled for the output.

Example uses PAB (Power Analysis Block) functionality to determine if measured value (load in our case) lies in given range for a period of time. When it does, defined Rule triggers device restart and sends alarm to Cloud.

  },
  "actions": {
    "OUTPUTS/1/ACTION": 2,
    "CLOUD/OUTPUT/1/ALARM": "${COND_RESULT}"
  }
}

CR05 - Load Watchdog with zones (indicate OFF / IDLE / RUN mode by switched on output)

Rule monitors load (Watts) on Output 1. Measured load is then classified to several zones defined with thresholds (limit values). Depending on the zone in which the measured load is currently located, different actions can be triggered. Load value has to be between defined threshold for at least 10seconds in order to be placed to respective zone. Example is composed of one PAB that classifies the zones and three Rules for 3 separate actions. Actions do the following:

• Output 1 load lower than 1W: Output 2 = ON
• Output 1 load between 1-20W: Output 3 = ON
• Output 1 load between 20-200W: Output 4 = ON

  }
}

CR06 - WatchDog for 2 IPs (Verify IP connectivity outage with 2 IPs)

The WatchDog functionality is used to monitor connectivity to specified IP address (or URL) by sending PING request to it.

In this example, we monitor two IPs and we want to restart device connected to Output 1 if none of the addresses reply. The ping for both IPs is sent every 30s and waits 5s for device to respond. There are 5 consecutive timeouts tolerated before the ping is considered as failed. When the ping fails, Watchdog returns false and remains in ERROR state.

In case both of the defined WatchDogs are in ERROR state, the Rule is triggered which then restarts Output 1.

WatchDogs definition

WatchDog name: CR06_WDT_1

  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}

CR07 - Synchronized outputs states during working hours

Rule keeps track of first output state and when it changes, it switches output 2 to the same state. However, we want this synchronization only to work during working hours. We define the time with Schedule functionality and use it as a filter (mask) in Rules. Schedule can be defined manually or imported as a configuration file.

Schedule definition

Schedule name: CR07_SCHEDULE

Rule definition

Rule name: CR07_RULE

{
  "conditions": {
    "OUTPUTS/1/STATE": "on"
  },
  "filters": {
    "SCHEDULE/CR07_SCHEDULE/ACTIVE": true
  },
  "actions": {
    "OUTPUTS/2/ACTION": "${COND_RESULT}"
  }
}

CR08 - Load Watchdog -> Turn output ON after period of time

In this example we want to measure load on output 1 and indicate when the power is abnormally low for a period of time by switching device on Output 2 ON (could be control light, sound alarm etc.).

In PAB we define indication for low power usage (1-20W) that is measured for period of 30 minutes (1800 seconds). In Rule we define switching Output 2 = ON (ACTION 1 = TURN ON) based on fulfilled PAB condition. This set up counts with human interaction after the Rule action gets processed. (e.g. restarting/replacing device on Output 1 and turning Output 2 OFF). It is possible to alter this behavior in such a way that the control light (Output 2) turns automatically OFF when load on Output 1 returns to standard values, i.e. higher than 20W (device gets repaired/replaced) or drops to 0W (device was removed or Output 1 turned OFF). This setup is defined in Rule NR08_ALT

PAB name: CR08_PAB

  "conditions": {
    "PAB/CR08_PAB/IN": true
  },
  "actions": {
    "OUTPUTS/2/ACTION": "${COND_RESULT}"
  }
}

CR09 - Digital Inputs with Schedule

Examples shows usage when we want to detect switching of Digital Input to ON state (1) but to (not) react only during specified hours (e.g. outside of working hours). Reaction hours are defined with Schedule functionality. Schedule can be defined manually or imported as a configuration file.

Schedule definition

Schedule name: CR09_SCHEDULE

Rule name: CR09_RULE

{
  "conditions": {
    "INPUTS/1/STATE": "on"
  },
  "filters": {
    "SCHEDULE/CR09_SCHEDULE/ACTIVE": false
  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}

CR10 - TURN OFF Output 1 before midnight

Rule in a combination with Schedule can be used to ensure a specified output will be turned off at the end of the day (or any other time). Schedule in this application is NOT assigned to the output and acts only as a "trigger" for launching the Rule action.

Schedule definition

Schedule name: off_before_midnight

Schedule configuration: Schedule is configured to have intervals every day from 23:59 to 24:00. In this configuration, the output turns of at 23:59.

Rule definition

Rule name: CR10_RULE

{
  "conditions": {
    "SCHEDULE/off_before_midnight/ACTIVE": true
  },
  "filters": {
    "OUTPUTS/1/STATE": "on"
  },
  "actions": {
    "OUTPUTS/1/ACTION": 0
  }
}

  "actions": {
    "OUTPUTS/3/ACTION": 4,
    "OUTPUTS/4/ACTION": 4
  }
}

CR13 - Actions based on daylight

Turns output ON/OFF based on sunrise/sunset times of set location. In this example, output 1 gets turned on one hour before (-60 minutes) sunrise and turns off one hour (60 minutes) after sunset. Location is se for NETIO Products headquarters (U pily 103, Prague, CZ). Elevation is set as 247 meters, above sea level.

  }
}

CR14 - Actions based on Power-UP / BOOT

This example describes rule that evaluates after device start-up. Generally, there are 2 options for setting up conditions:

• SYSTEM/DEVICE_POWER_UP - device boot after power-cut
• SYSTEM/DEVICE_BOOT - every device boot (power-cut, periodic restart, firmware update etc.)

Condition in rule description below reacts to device boot after power-cut. When device first starts after regaining power, it sends alarm to output 1 in NETIO Cloud service.

Rule definition

Rule name: CR14_RULE

{
  "conditions": {
    "SYSTEM/DEVICE_POWER_UP": true
  },
  "actions": {
    "CLOUD/OUTPUT/1/ALARM": "${COND_RESULT}"
  }
}
