mbaxp.ocx : Free Download

The "mbaxp.ocx" ActiveX control, developed by Witte Software and written by Brian Witte, is part of the MBAXP Modbus Master ActiveX Control suite. This control is designed for implementing Modbus communication in Windows applications, allowing a system to act as a Modbus master for controlling and exchanging data with Modbus slave devices.

Key Features and Functions:

• Modbus Protocol Support: Supports communication using the Modbus protocol, including both RTU (serial) and TCP/IP, enabling data exchange with Modbus-compliant devices such as PLCs, sensors, and meters.

• Master Role: Operates as a Modbus Master, allowing it to send commands and requests to Modbus slave devices and retrieve data in real time.

• Data Reading and Writing: Provides functions to read from and write to Modbus registers, including coil status, input status, holding registers, and input registers.

• Flexible Communication Options: Offers customizable communication parameters such as baud rate, parity, and timeout settings, ensuring compatibility with a wide range of Modbus networks and devices.

• Error Handling: Includes error detection and handling capabilities for ensuring reliable communication, especially in industrial environments.

• Event Handling: Provides event-driven programming, allowing developers to respond to specific Modbus communication events, such as data retrieval or communication errors.

Applications:

• Industrial Automation: Ideal for building systems that control and monitor industrial equipment such as PLCs, drives, and sensors through the Modbus protocol.

• SCADA Systems: Suitable for Supervisory Control and Data Acquisition (SCADA) applications that require real-time data exchange between a master system and multiple Modbus slave devices.

• Energy Management Systems: Can be used to collect data from power meters, gas meters, or other utility devices that communicate via Modbus for energy monitoring and analysis.

• Building Automation: Useful in building control systems that interact with HVAC units, lighting systems, and other Modbus-compatible devices for centralized management.

Summary:

In summary, "mbaxp.ocx" is a robust Modbus Master ActiveX control, developed by Witte Software, that enables reliable communication with Modbus slave devices. It offers comprehensive support for both Modbus RTU and TCP/IP protocols, making it a valuable tool for developers working on industrial automation, SCADA, energy management, and building automation systems.
