Pigeon PLC

  • The Pigeon PLC RB100/RB300 is a Linux-based programmable automation controller, ready for use in your automation project.
  • Analog and digital inputs and outputs follow industrial standards and work well with commonly used sensors and actuators.
  • RS-485 and 1-Wire buses allow connection of additional I/O units, sensors and various devices like servo drives or energy meters.
  • Excellent price to performace ratio, ideal for education and training in automation.
  • Universal platform for proof-of-concept prototyping and for low-cost automation projects.
  • The Pigeon PLC is powered by the Raspberry Pi Compute Module.

Typical use-cases

  • Reading and archiving data from standard industrial sensors
  • Monitoring of machines
  • Universal automation controller for non-critical applications
  • Communication gateway between various devices
  • Control of experimental setups and plants

No more hand-coding

The runtime core of the REXYGEN system turns your Pigeon PLC into a programmable device which will run your algorithms.

The REXYGEN system offers a graphical development environment for programming the algorithms. You can use standard desktop or laptop PC. You create the algorithms from the so-called function blocks (*). The library includes countless items (timers, comparators, filters, PID controllers and many more). Learn more about REXYGEN Studio.

*) The IEC 61131-3 standard defines Function Block Diagram (FBD) as one of the PLC programming techniques.

Input and output signals, external devices

  • Direct inputs and outputs (DI, DO, AI, AO)
  • 1-Wire sensors and actuators (temperature sensor DS18B20 etc.)
  • Modbus TCP or RTU devices (input-output units, energy meters, servo drives, ...)
  • Siemens PLCs (LOGO! and S7)
  • SQL database import/export (via ODBC)
  • Third party devices with generic RS-232 or RS-485 serial interface
  • Third party devices with generic TCP or UDP communication
  • Cloud services (REST API, HTTP GET/POST)

Human-machine interface (HMI) for your project? Checked!

  • The built-in webserver of the REXYGEN runtime core turns the device into an all-in-one solution.
  • Our HMI frameworks rely on HTML5 and work in all common browsers on Windows, macOS, Linux, iOS and Android.
  • You can use an automatically generated HMI for your desktop, tablet or smartphone. You are also free to design your very own HMI.
