Product Description
The software contains the full functionality of the IEC104 protocol. Remote signaling, remote control, remote adjustment, telemetry, etc.
The domestic number of this agreement is DL/T634.5104-2002, referred to as IEC104 protocol, question-and-answer protocol, based on TCP/IP protocol
Application environment (network data communication between the substation and the control center, generally using a balanced mode) Frame format (U format frame, S format frame, I format frame) Network port number (2404)
IEC104 Packet Analysis Example:
68 boot frames
0E data length--- control domain + application service length: 14
10. Control domain 1--LSB sends serial number N(s) bit1~bit7, bit0:0
Dual-point remote control message 08 control domain 2--MSB transmits sequence number N(s): 2056
00 control domain 3 -- LSB receives serial number N(s) bit1~bit7, bit0:0
12 Control domain 4 -- MSB receive serial number N(s): 4608
