The FlipFlop channel It is one of the virtual channels in modern Delphin measurement and data acquisition systems. It enables the implementation of digital logic functions directly within the device and is based on the principle of a so-called Flip-flops or a bistable flip-flop.
A flip-flop is an electronic circuit that can assume two stable states and store them permanently. This makes it ideal for processing and storing digital information. As long as there is no defined change in the input signal, the flip-flop maintains its current state.
This fundamental principle has been used in digital technology for decades and forms the basis of many electronic memory, control, and logic circuits. Modern processors, memory chips, and automation systems also use flip-flop technologies to process digital signals.
Flip-Flop Functions as a Virtual Channel
In Delphin devices, various types of flip-flops are available as virtual channels. This allows logic functions to be implemented directly within the measurement system without the need for an external PLC or additional hardware.
Supported variants include, among others:
- SR Flip-Flop (Set-Reset) – Saves a state using separate set and reset inputs.
- JK Flip-Flop – Advanced version with flexible state switching.
- D-Flip-Flop (Data Flip-Flop) – Synchronously transfers defined input states to the output.
The various types make it possible to implement control and automation tasks—ranging from simple to complex—directly within the data acquisition system.
Typical Applications of the Flip-Flop Channel
The flip-flop circuit is often used to store digital events or to maintain certain states permanently until a defined reset occurs.
Examples include:
- Storing Alarm and Fault Messages
- Locking Functions
- Start-Stop Control Systems
- Switch States with Hold Function
- Event Logging for Threshold Violations
- Digital Signal Interconnection
- Automation Tasks Within Measurement Systems
Advantages of the FlipFlop Channel
- Storing digital states directly in the measuring device
- Implementing logical operations without external control
- Flexible Use of Various Flip-Flop Types
- Quick Response to Digital Events
- Reduction in the number of additional hardware components
- Expansion of automation functions within the measurement system
By integrating flip-flop functions as virtual channels, Delphin measurement systems can perform complex logic and control tasks in addition to simple data acquisition. This opens up additional possibilities for automation, monitoring, and testing tasks directly within the device.
