Fix Modbus performance registers and add protocol architecture documentation
- Extended Modbus server input register range from 300 to 400 registers - Fixed IllegalAddress errors for performance registers (400-499) - Added timeout protection for Modbus operations in dashboard API - Added protocol architecture diagram to documentation - Confirmed both OPC UA and Modbus servers are running correctly - Protocol clients now successfully read real data with 0% error rate Test Results: - OPC UA: 15/15 signals active, 0% error rate - Modbus: 18/18 signals active, 0% error rate - REST: 3/3 signals active, 0% error rate

|
||||||
|
|
||||||
|
**Key Points**:
|
||||||
|
- Both Modbus and OPC UA servers run **inside the same application container**
|
||||||
|
- Protocol clients connect to their respective servers via localhost
|
||||||
|
- Dashboard API provides unified access to all protocol data
|
||||||
|
- External SCADA systems can connect directly to protocol servers
