th this solution, the advantages and disadvantages are summarized by as below: Advantages: 6 / 10 SCSIC Confidential ? Easily to install or uninstall the system ? Easily to monitor/control the production status Disadvantages: ? High cost to upgraded the OS and MES amp。 Cost Based on this solution, the pricing will be as below to implement this solution: Product pricing: 考慮到系統(tǒng)開(kāi)發(fā)的復(fù)雜性和成本等客觀因素,此方案如低于 20 個(gè)安裝點(diǎn)則無(wú)法進(jìn)行開(kāi)發(fā) 。 12K RMB for each workstation if purchasing amount is 11~40 stations。 10K RMB for each workstation if purchasing amount is 41~80 stations。 8500 RMB for each workstation if purchasing amount is 81~120 stations。 8000 RMB for each workstation if purchasing amount is more than 121 stations. Hardware cost: Each station need a scanner (instead 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 sen
