4. Functionality

The RIO-2010 functions as a remote digital I/O expansion module that communicates with host systems via Modbus/TCP or Modbus RTU/ASCII. It can be deployed in distributed control systems, data acquisition networks, or IoT environments.

Operation Modes:
- Modbus/TCP Mode: Communicates over Ethernet with Modbus masters such as PLCs, SCADA servers, or IoT gateways.
- Modbus RTU/ASCII Mode: Communicates via RS-485 bus with Modbus masters in serial networks.

Web-Based Control:
The built-in web server allows users to monitor and control I/O channels through a browser. The default web interface demonstrates AJAX-based dynamic control, and users can upload customized web pages for specific applications.

HTTP API Access:
- GET Request: `/action/fetchValue?all_val=0` retrieves DI, DO, and sensor data in JSON format.
- POST Request: `/action/CtrlDO` sets relay outputs (e.g., `DO01=H` energizes relay 1).

CLI Configuration:
Accessible via Telnet or serial console using Artila’s proprietary command syntax. Commands follow the format `[G/S]:Command=Parameter` and can configure network settings, Modbus modes, and I/O parameters.

Use Cases:
- Industrial automation and process control
- Remote equipment monitoring
- Building management systems
- Environmental data acquisition
- IoT sensor integration via 1-Wire interface

Compatibility:
- Works with standard Modbus masters (PLCs, SCADA, DCS)
- Integrates with Artila’s IoT gateways and Node-RED environments
- Supports Windows configuration utility for setup and management
