Application range: The 101 and 104 communication protocols are commonly used to communicate between electric power remote control center and monitoring terminal


Protocol structure: same definition of application layer


Communication mode: The 101 protocol is generally used for serial communication, and can also be used in UDP mode. The 104 protocol is generally used in network communication, using TCP/IP mode. The 104 protocol is network version of the 101 protocol


Service type: the 101 mainly use unbalanced transmission, one party initiates communication, the other responds. The 104 mainly use balanced transmission, both sides can initiate communication
