AIBUS communication protocol is developed by Yudian, which is simpler and faster than MODBUS protocol. For example: it takes only 20ms to read 3 common variables and 1 parameter in 19.2K baud rate, which is 2~10 times faster than MODBUS. Yudian developed AI-MODBUS converter to realize communication between MODBUS and AIBUS protocol by one single bus and make two different protocols compatible.
