Autonomous Features

The TOAA Timer/Operation/Autonomous/Action/  feature lets you setup the RAZN to do what you want it to do automatically. Raveon filed a US provisional Patent in 2020 for this spectacular RAZN technology.

This Autonomous IoT device (AIoT) works on networks or Cloud servers, but it also work great,  autonomously, without necessary network or IoT connections.

Set Timers: To trigger an specific Operation event.

Setup Operations:  To do, such as read digital inputs, read buttons, read voltages, check register values, read temperature, or dozens of other operations. If the operation triggers an Action, it will take an Action.

Setup Actions: To do if the operation triggered an alert. Put out a voltage, send a message, turn on an light, turn on a valve, beep a siren, send a text message, send a SCADA alert,  of dozens of other actions.

At the end of the Action time duration you choose a Final Action takes place if you want.  Turn off the light, turn off the valve, turn off the sirent, or whatever final action you desire.

The RAZN also does many other Autonomous things other RTUs cannot do:

1. Count the number of changes in an input (digital in, button, light sensor,..)
2. Record the time a digital input, or button, or sensor, goes up to a 1 or down to a 0.
3. Record the maximum value in some registers that measure voltages, pulses/second, pulses/minute, pulses/hour.
4. Change an output based upon the status of some inputs, such as voltages, pulses, digial bits, buttons, …
5. Periodically send the status of some inputs, registers, or sensors.
6. Send text messages out based upon status of inputs or registers.

IoT Wireless Technology

The IoT consists of an array of new devices that are very different to tablets and PCs. This is the RAZN.

IoT devices like the RAZN are:

• They are low powered – battery, solar, and low current.
• Low unit cost
• They will have limited processing power and memory, although the RAZN is smart and Autonomous processor.
• Operate over a wide variety of ranges, and the RAZN has more wide-range options than any other IoT device.

The Wide Area Network (WAN) range if the RAZN can cover from 10kM to 200kM. Raveon offers a variety of radio options for all types of systems.

IP Capable Technologies

Whether or not a technology is IP capable is an important thing to bear in mind.

The RAZN is wireless technologies and IP capable, so it does have an IP address.

Cost & Maintenance

Wire and conduit are expensive and high maintenance. As the price of copper increases, so does the possibility that your wire will be stolen. Wear-and-tear, digging, and rodent damage are all examples of problems that can damage wire.

You can use wires with the RAZN, or go wireless or both.

1. The TOAA Timer in the RZN that triggers time can be set to:
2. When the Timer triggers, you specify the Operation this Remote Zone Node (RZN) should perform.  The Operation is setup to read inputs, and registers, which for you can read.
3. When the Operation reads what you want, it will trigger an Action based on your desires. If the Operation reading did not cause an Alert, then nothing else will happen.
4. If the Operation caused an Action to take place, the actin that takes place is setup by you. The RZN can perform many different Actions.
5. The Final Action is the action that will take place at the end of the duration of the TOAA Timer.
