FBD program editor "ALPHA"

Author

FBD Program Editor "ALPHA" is a free software developed by TOV "MICROL", designed for creating, debugging, and uploading control programs to microprocessor-based controllers of the MIK series.

⚙️ Main Purpose:

The ALPHA editor enables the development of controller logic in the form of Function Block Diagrams (FBD) — in accordance with the IEC 61131-3 standard, which is the international standard for PLC programming.

🧰 Key Features:

✅ Graphical programming environment — programs are created by placing function blocks and connecting them with lines.

✅ Function block library includes:

• Logical: AND, OR, NOT, triggers, pulses, etc.
• Arithmetic: addition, multiplication, integration, differentiation, etc.
• Specialized: timers, counters, converters, etc.
• Control: PID controllers, position regulators, and various other types.
• Time & Date: timers, pulsers, stopwatches, pulse generators.
• Process tools: filtering, linearization, switching, data output, step-by-step program block.

✅ Support for various variable types: BOOL, INT, UINT, FLOAT.

✅ Modular design support — save and import diagram fragments.

✅ Real-time debugging (available only when connected to a controller):

• Online mode with controller via RS-485.
• Live variable value display directly on the diagram.

✅ Program upload/download to/from controllers of the MIK-51, MIK-52, MIK-51N, MIK-52N series.

🖥️ System Requirements:

• Windows OS (XP, 7, 10).
• RS-485 port (via USB-RS485 converter or COM port).
• Device driver and communication cable are required for operation.
