    The Operation is setup to read inputs, and registers, which for you can read. Registers have values, IO counters, IO status, IO timers, and many others.
    The your desired operation takes place and can cause a Trigger or be ignored based on your operation thresholds.
  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 RAZN can perform many different Actions for an Operation that triggered.
  5. The Final Action is the action that will take place at the end of the duration of the TOAA Timer.


TOAA sets up the minimum time between consecutive unsolicited messages sent by the outstation (Master or Slave)

TOAA Autonomously can do whatever you want to do and whatever time you want,
and TOAA Autonomous operations can save your system incase you SCADA communications  or network were to fail.

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
