About Commsman

Version 1 Release

Commsman (Communications Manager) is a powerful, extensible tool for testing, monitoring, and managing industrial communication protocols. It is designed to help engineers and testers interact with embedded systems, PLCs, and other field devices via common industrial protocols.
Currently, Commsman supports Modbus TCP and Modbus RTU protocols, with a focus on usability, structured data organization, and continuous monitoring.

⚡ Industrial Protocols

Commsman comes with native support for Modbus TCP and Modbus RTU, allowing you to connect with your industrial devices in minutes. No external libraries, no complicated setup—just plug, configure, and test.

📊 Real-Time Monitoring

View responses, errors, and execution times as they happen. Every request and collection logs its own history, making it easy to debug devices, validate behavior, or analyze network performance over time.

🧩 Modular and Extensible Architecture

Structure your work into nested collections, reuse Modbus clients across requests, and automate repetitive tasks. Whether you're running a single test or a full system validation, Commsman scales with you.

Core Features at a Glance

All-in-One Industrial Protocol

  • Collections-Based Architecture 

    Structure your workflows with nested Collections and Requests for clarity and reusability.

  • Request Execution

    Send Modbus requests with full control over function code, address, quantity, and more — with real-time feedback.

  • Continuous Monitoring

    Set up polling cycles and watch live updates and historical trends from both Collections and individual Requests.

  • Request Request History

    Every request automatically records timestamped logs — both for TCP and RTU.

  • Client Inheritance

    Requests can inherit Modbus clients (TCP or RTU) from their parent collection — for fast, DRY configurations.

  • Clean, Collection-Based Design

    Organize your communication flows like folders and files — intuitive and scalable.
