The picture configuration of the man-machine interface that operator of 1WinCC configuration software stands uses the SIMATICWinCC4 of Xi Menzi company.

0 labour control configuration software. SIMATICWinCC (WindowsControlCenter) be development of Xi Menzi company is complete 32 distributinging automation controls configuration software, winCC has powerful function and height to open a gender as software of configuration of a monitoring, can make side of user design outside good, the supervisory system with perfect function; And the convenience function that can use each Windows below Windows standard environment as a result of it, can shorten greatly the time that happens into process software package. WinCC software basically includes data to collect govern 2 basic functions with data. Data is collected is to point to collect data from the spot and undertake corresponding processing, collect basically finish by the PLC that controls a station as the spot. Data management is a data that gets from the spot the database that undertake processing hind and sends a server it and by the database visit function reads access to arrive according to sending again next in application. 2.
