A Remote Autonomous Zone Node (RAZN) is for smart SCADA and Telemetry node with general purpose control capability in a compact, cost-effective package. RAZN can switch on/off 8 AC and DC power outputs, and convert up to four analog devices, 8 digital inputs, and 2 switch inputs, into: EtherNet/IP or Modbus-TCP. This is a RTU and has many more IoT and wireless features than most traditional RTUs.

Reduce your system cost by using Remote Autonomous Notes With Wireless modems built in.

Switched AC and DC power connections and Flexible IOs

User Wires (Ethernet, RS485, USB)  or  use Wireless (ISM, LoRa, UHF, VHF)

Optically Isolated switched power outputs and reverse power protected.

Its Autonomous operation makes it work great over time as needed, without the need to connect to the internet or other networks.

Flexible Input/Output Options:  Digital, Switching AC or DC Power, Voltage, Current, buttons,…

The RAZN is a Remote Terminal Unit (RTU)  used to monitor and control a variety of devices and systems. An RTU is similar to a programmable logic circuit (PLC) but has more in-depth functionality. A  key component of a the RAZN is the ability to send and receive real-time data.

Autonomous Features

The TOAA Timer/Operation/Autonomous/Action/  feature lets you setup the RAZN to do what you want it to do automatically.

Set 1-16 Timers: To trigger an specific Operation event.

Setup 1-16 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 1-16 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:

  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.

Smart and High Performance

Designed in 2018, the ARM processor is much higher performance and lower power than RTUs design 10 years ago. CPU processing power provides accurate data analysis and communication for the most critical, and demanding SCADA applications to ensure optimal operation.

The RZN is designed to use a variety of digital, analog, and switched power interfaces so you are never locked into proprietary solutions. The flexible communications capability enables the RZN to connect with hundreds of local devices, analyze the data, and send that status information to various other locations. Data transmission and processing is supported simultaneously across multiple communication media and industry standard data protocols including MODBUS.

Real-Time Process Automation And Robust Communication

The RZN’s General Purpose IOs (GPIOs) can be sedup in any way you want. Each GPIO has many configuration options.

  1. Digital Inputs
  2. Digital outputs

Timer Operations Actions and Alerts   (TOAA)

How the TOAA Timer Works.  Timer Operation Actions can be setup in any way you would like.
The TOAA smart timer technology in the RXN can be used to:

On a specific time of day, turn on specific outputs to control light, valves, pumps, doors, …

  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.

Setup Remote Networks with the RZN

A RZN can communicate with many other RZNz and pass along data to them or get data from them.

Your system can connect to one RZN, and it will work with as many others as needed.

And for even larger systems, use a Cigorn Gateway to route data to-from multiple Telemetry Networks.

As seen on the left, the gateway can communicate with 1 or hundreds of RZNs.

One RZN can manage a complete local network of many RZNs or GPIO radios in a Remote Zone Network.

The Cigorn Gateway can talk to even thousands of RZNs so you can have thousands of Remote Zone Networks

Autonomous Smart IO Management

This RZN is smart and can AUTONOMOUSLY manage the IO pins itself. You can use a master controller or HMI device to control the IOs or setup the RZN to manage the IOs itself. The RZN has more IO management features than any other RTU in the industry. There are commands within the RZN to setup all these features to just run in a remote are with no network connection, if you want to have it just autonomously read inputs and manage outputs based upon the inputs and time and date.

Here is a list of the features. You can choose and setup an Feature ID and Threshold Value (TV). When a Feature measures something you want, it will Control State of an Output Pin (CSOP) as you want it to do. When it Controls the State and Output Pin (CSOP), it can turn on or off a switched DC output, switched AC output, a digital output state, or turn on or off an Open Drain output.

‘A’ Angle of the unit.                      If the physical angle (X, Y,  or Z) angle of the unit goes beyond the TV it will do the CSOP.

‘B’ Raw Input Binary Event           If a digital input (TTL, button…) got into a mode you choose (0 or 1, On or Off), then it will do the CSOP.

‘C’ 4-20mA Input Current              If a the input current on a 4-20mA input sensor goes beyond the TV it will do the CSOP.

‘D’ DC input or Battery               If a internal power voltage goes above or below the TV it will do the CSOP in the way you want.

‘P’ Pulse Ticking Event                 If a digital input (TTL, button…) pulsed on/off more times per second or minute that you want, it will do the CSOP in the way you want.

‘R’ Pulse Ticking Event                If a internal vibration sensor pulsed on/off more times per second or minute that you want, it will do the CSOP in the way you want.

‘T’ Product Temperature               If the RZN’s temperature sensor goes above or below the TV it will do the CSOP in the way you want.

‘#’ Internal Register Value             If the internal register value within the RZN voltage goes above or below the TV it will do the CSOP in the way you want.

The Benefits of Autonomous Data Monitoring and Control

Fast finding critical data

The RZN reads inputs, status, sensors, timers, and clocks in real-time.

The RZN can use the information, and control outputs based on inputs, status, sensors, timers, and clocks in real-time.
