2. Key Selling Points

1. Dual-Port 10/100 Mbps Ethernet Connectivity
   Features two built-in Ethernet ports (10/100 Mbps, auto-negotiation), supporting flexible network topologies such as star, line, or ring configurations—ideal for robust industrial networks.

2. Supports Multiple High-Level Protocols
   Enables communication using TCP/IP, UDP/IP, FTP, and HTTP, allowing the CJ-series PLC to exchange data with SCADA systems, HMIs, databases, and other networked devices.

3. Built-in Web Server for Remote Monitoring
   Includes an embedded web server that allows users to monitor PLC status, I/O data, and network settings via any standard web browser—no additional software required.

4. E-mail Notification & Event Alerts
   Can be configured to send e-mail alerts when specific events occur (e.g., alarms, faults, system startup), enabling proactive maintenance and remote diagnostics.

5. Seamless Integration with CJ-Series PLCs
   Mounts directly onto the CJ1 backplane, receives power from the rack, and exchanges data via I/O memory mapping—no external power supply or PC connection needed.

6. FTP Server/Client for Program & Data Management
   Supports FTP file transfer (both server and client modes), enabling remote program backup, firmware updates, and data logging without interrupting PLC operation.
