The software system PLC is designed for a control of industrial production lines according to jit data from a manufacturer. The system controls a sequence of products on an assembly line, defines technological data for work positions and checks technological operations during the assembly. Specialised software modules compose the whole system. These modules are distributed on PCs on a LAN network. All technological data are processed in accordance to ISO 9000.
3 main functions of PLC
Control function - Data are sent to modules on each work position and these modules control an assembly.
Checking function - All supervised operations on each product are checked in real time during an assembly.
Documentation function - Data are stored into an SQL database and then can be stored onto non-rewritable media (e.g. CD-R discs). A www search engine for finding the data is available.
