Rules Complete Examples

Example for PAB - RANGE (multiple actions for one condition)

Defined condition checks a device connected to output 4. The device is expected to have a maximum load of 600W. If the load is too high, we want to immediately turn off the device and send an alarm to Cloud.

PAB definition

PAB name: Watch_out4_load

{
  "type": "RANGE",
  "source": "OUTPUTS/4/LOAD",
  "lowerBound": 0,
  "upperBound": 600
}

Action definition

{
  "conditions": {
    "PAB/Watch_out4_load/IN": 0
  }
  "actions": {
    "OUTPUTS/4/ACTION": 0,
    "CLOUD/OUTPUT/1/ALARM": "${COND_RESULT}"
  }
}

Example for PAB - ZONES

In this condition, the value of current at the output 2 is monitored. It is then classified to respective zone according to measured value. Depending on the zone in which is classified, different actions can be triggered:

• If the value of current is in zone 0, restart device on output 1
• If the value of current is in zone 2, turn ON alarm in Cloud

PAB definition

PAB name: Watch_out2_current

{
  "type": "ZONES",
  "source": "OUTPUTS/2/CURRENT",
  "thresholds": [
    50,
    150,
  ],
  "timeHysteresis": 10
}

Rules definition

Must be defined in two separate Rules because they contain different conditions:

• Rule name: Zone_restart
• Description: If the PAB is in zone 0 (0-49mA), restart the device at output 1

{
  "conditions": {
    "PAB/Watch_out2_current/ZONE": 0
  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}

• Rule name: Zone_alarm
• Description: If the PAB is in zone 2 (150+ mA), send alarm to Cloud

{
  "conditions": {
    "PAB/Watch_out2_current/ZONE": 2
  },
  "actions": {
    "CLOUD/OUTPUT/1/ALARM": "${COND_RESULT}"
  }
} 

Watchdog example

The Watchdog monitors specified IP address. The ping is sent every 60s and waits 5s for the device to respond. If the ping fails twice in a row, Watchdog returns false and restarts the device. After restart, it waits 120 seconds and starts monitoring again. This cycle repeats a total of 3 times, and if the device does not respond even once, the Watchdog remains in ERROR state.

Watchdog definition

Watchdog name: Watch_101_180

{
  "target": "192.168.101.180",
  "pingInterval": 60,
  "timeout": 5,
  "maxTimeouts": 2,
  "timeToReboot": 120,
  "maxRestarts": 3 
}

Rule definition

Rule name: Watch_101_180_restart

{
  "conditions": {
    "WDT/Watch_101_180/FAIL": true
  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}
