DF-1 Protocol
DF-1 / DF1 protocol is an asynchronous byte-oriented protocol that is used to communicate with most Allen Bradley RS-232 interface modules. DF1 protocol consists of link layer and application layer formats. DF1 works over half duplex and full duplex modes of communication. Application layer messages Application layer message format consists of ''Command Initiator messages'' (request messages) and ''Command Executor'' (reply messages). Important command initiator messages are as follows. * apply port configuration * bit write * change mode * close file * diagnostic status * disable forces * disable outputs * download request * echo * enable outputs * enable PLC scanning * enter download mode * enter upload mode * exit download/upload mode * file read * file write * get edit resource * initialize memory * modify PLC-2 compatibility file * open file * physical read * physical write * read bytes physical * read diagnostic counters * reset diagnostic counters * read link parameters * ...

Dongfeng-1
The ''Dongfeng'' () series, typically abbreviated as "DF missiles", are a family of short, medium, intermediate-range and intercontinental ballistic missiles operated by the Chinese People's Liberation Army Rocket Force (formerly the Second Artillery Corps). History After the signing of the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance in 1950, the Soviet Union assisted China's military R&D with training, technical documentation, manufacturing equipment and licensed production of Soviet weapons. In the area of ballistic missiles, the Soviets transferred R-1 (SS-1), R-2 (SS-2) and R-11F technology to China.13,000 km). Currently, an estimated 24-36 DF-5A's are in service as China's primary ICBM force. If the DF-5A is launched from the eastern part of the Qinghai province, it can reach cities like Los Angeles, Sacramento and San Francisco. If it is launched from the most eastern parts of northeastern provinces, it can cover all of the mainland of the Unit ...
