B. Working Principle of ATC-1300 Modbus Gateway

The ATC-1300 works as a bridge between serial communication devices and Ethernet networks.

In traditional industrial systems, many devices such as PLCs, meters, sensors and controllers communicate through serial protocols like RS-232, RS-485 or RS-422. However, modern automation systems often require Ethernet-based communication for remote monitoring and centralized control.

The ATC-1300 receives serial data from connected devices and converts it into Ethernet TCP/IP communication. Similarly, Ethernet commands received from PLC, SCADA or HMI systems are converted back into serial communication signals for connected field devices.

The configuration process is performed through a web interface or configuration utility. Users can set IP address, serial communication parameters and network settings according to application requirements. After configuration, the gateway enables continuous and reliable data exchange between connected devices.
