System Schematic Diagram
A: I/O port connections;
B: Through GPRS or 3G to HMI, OMC, the TCP/IP protocol is KingPigeon Definition Protocol.
C: Through GPRS or 3G to SCADA,HMI, DCS, OPC Server, Under this condition, the RTU performs Modbus
Slave. And the TCP/IP Protocol is Modbus TCP.
D: Using SMS to control the RTU, or receive SMS alarm alert, or through voice communication to open the door
or receive alarm calling.
