d by keyboard) and the price is about 3K RMB for each one (two dimension is to support the barcode) One LOG Server is required for this solution and the price will be about 10K RMB 7 / 10 SCSIC Confidential transit exchange (XP or above OS) for each workstation Diagram4: Architecture for Transit Exchange Version Architecture description: This solution is based on standalone model and one transit exchange machine (with XP or above) will be added for each work station. The work flow will be explained as follows: ① The input equipment (keyboard or scanner) get the right barcode to system ② The system sent the message to transit exchange server to get the program name( munication way between workstation and transit exchange is serial port) ③ The transit exchange send the message to IT program server to get the program name ④ IT program server response the right program name to transit exchange server ⑤ The transit exchange server response the program name to workstation, the control system will automatically invoke the MES to run the program. ⑥ The transit exchange server will send the operation log to Logging server to record all the operations( including getting program names with barcode, when to 8 / 10 SCSIC Confidential start run the program, etc) The Logging server can stored the operation log and do the statistics analysis with these data. Such as result will be classified by types: ? How many stops generated by wrong programs? ? How many wrong operations made by wrong barcode? ? Which station, wh
