Communication
Modbus TCP and RTU workflows for master polling and slave simulation.
Features
Everything needed for day-to-day Modbus engineering work
Grouped around communication, monitoring, configuration, simulation, automation, and data handling.
Monitoring
Live tag values, polling state, diagnostics, and read/write operations.
Configuration
Readable register, group, tag, and data-type setup with validation before apply.
Simulation
Slave-device simulation to test masters, HMIs, SCADA systems, and protocol behavior.
Automation
Script runner and automation tools for repeated diagnostic and commissioning tasks.
Data handling
Import, paste, validate, save, and export configuration data, including AI-assisted JSON templates.
Master monitoring
Live monitoring for real Modbus devices
Use modbusAI as a Modbus TCP master or Modbus RTU master to poll configured registers, inspect tag values, and perform controlled write operations.
TCP and serial connection workflows
Live polling and read/write operations
Grouped tags for readable diagnostics
Debug information for communication review
Slave simulation
Simulate devices without waiting for hardware
Host Modbus slave behavior for master, HMI, SCADA, commissioning, protocol, or demonstration work.
TCP slave simulation
RTU slave simulation
Reusable register maps
Useful for FAT, SAT, and bench testing
AI JSON Template Tool
AI can help prepare the map, validation keeps the engineer in charge
Create or refine JSON templates with AI assistance, paste them into modbusAI, preview changes, and validate the result before applying it.
Paste JSON configuration
Preview before apply
Register and tag validation
Import and export workflow
Register configuration
Readable configuration for engineering and maintenance
Build register groups, tags, data types, and metadata in a way that supports monitoring, simulation, and later reuse.
Groups and tag names
Standard register areas and data types
Configuration save, load, import, and export
Validation preview before applying changes
