FIELD: engineering of data transfer systems for performing automatic control over manufacture of products from glass. ^ SUBSTANCE: system has multiple electronic devices, meant for performing operations over products made of glass, and also network, mutually connecting devices for mutual information transfer, and including network concentrator of star type and connections, connecting aforementioned concentrator to multiple devices in accordance to network configuration of star type for two-directional data transfer among these devices through concentrator. Network concentrator includes controller, meant for controlling concentrator operations in accordance to communication protocol CANbus, circuits, meant for initialization of measurements and data transfer from one of devices, and circuits, meant for blocking transfer of such data from device, data transfer from which was initiated, and allowing data transfer from device through network concentrator of star type through other devices, connected to concentrator. ^ EFFECT: increased overall efficiency of data transfer. ^ 7 cl, 9 dwg |
