Power supply unit: be mainly used in providing various power supply signal to system.
Communication unit: be mainly used in the communication of setting up between PLC and controller.The data (lathe task and state) needing to transmit are sent to the light-coupled isolation chip of this controller by PLC by 6 groups of general digital quantity output interfaces, after light-coupled isolation, be sent to control module.In this controller, to define before 6 groups of digital quantity signals 3 groups is Status Information Frame, and latter 3 groups is Frame, as: 111001 current datas representing No. 7 status frames (111) are 1 (001); The current data of 001100 expression No. 1 status frames (001) is 4 (100), by that analogy.
Control module: for receiving the six circuit-switched data information that PLC is sent by light-coupled isolation chip, export the three circuit-switched data information controlled required for display unit, meanwhile, by SCI communication interface, the plc data received is sent to SCI receiver module (as PC) in real time.In this controller, the three circuit-switched data information that define are respectively: enable information, clock information and data message.Enable information is that low level represents that these data are effective, and the square-wave signal of clock information to be frequency be 1KHZ, data message is the concrete data that controller sends, and display unit reads this data when clock data is low level.
Display unit: send three-wire system serial data by reception control unit, in real time the data received are presented at LCD, LED screen.
Technique effect:
1. achieve the data interaction with all types PLC system by employing six universaling I/O ports;
2. define three-wire system serial data bus, achieve the display and control to LCD, LED;
3. devise extendible RS232 universal serial bus, facilitate storage and the debugging of data;
4. adopt high speed photo coupling isolation, ensure that signal-obtaining stability.
