Modbus Gateway vs Traditional Point-to-Point Communication
| Feature | Modbus Gateway | Traditional Serial / Point-to-Point |
|---|---|---|
| Network Readiness | Built for serial-to-Ethernet and SCADA bridging | Usually remains isolated at device level |
| Scalability | Better suited for plant-wide and multi-system integration | Limited and harder to expand |
| Protocol Flexibility | Supports Modbus RTU, Modbus TCP, and additional industrial protocols | Often restricted to a single serial communication path |
| Remote Monitoring | Strong fit for SCADA and Ethernet-based monitoring | More difficult to expose remotely |
| Integration Complexity | Simplifies bridging of Modbus field devices and control systems | Higher effort for cross-platform integration |
