Calculate to be connected with the signal output part of processing unit and have output mapping register unit, described output mapping register
Unit connects output interface unit, and described output interface unit signal respectively connects the controller of external equipment.
Improving as one, described communication device includes 8255A communication interface.
Present invention also offers the method for work of a kind of above-mentioned control system, comprise the following steps,
Step one, upper electric scanning: after central processor CPU powers on, system is once initialized, including
Hardware initialization and software initialization, have a power failure and keep range set and the initialization of peripheral equipment control；
Step 2, self diagnosis scan: the every run-down of central processor CPU, perform a self diagnosis inspection,
Determining the running status of system itself, if there is fatal error, central processor CPU is forced to stop, and terminates sweeping
Retouch；
Step 3, Communications service: after self diagnosis scanning result is normal, central processor CPU inspection is either with or without logical
News task, if having, calling corresponding program, carrying out communication with its ancillary equipment；
Step 4, input sample: the switching value reading in all lathes that native system is controlled in order is defeated
Enter signal, and the data of reading are stored in corresponding input mapping register unit；
Step 5, data process: data and state to input and output mapping register unit carry out logic
Computing and process, and the content of output mapping register unit is refreshed according to result；
Step 6, control output: by the state in output mapping register unit with the form of control signal
The controller of external equipment is delivered to by output interface unit.
Owing to have employed such scheme, the invention has the beneficial effects as follows: this control system central processing unit CUP has
Having superpower data acquisition, computing, disposal ability, quantity processes to use supports general C language or compilation
The processor of language, processes digital or analog by the way of scan round processes logical language statement
Input/output, controls various types of machinery or production process.Have stronger switching value logical memory,
Judge, data operation, disposal ability, and have that volume is little, functional diversities, reliability high, price
The feature such as low；Native system compact conformation, cost are low, with strong points, expand fully according to needs when design
Fill I/O interface, select imput output circuit and the type of device and memory size, constitute neatly certainly
The control system that oneself is suitable for, does not has unnecessary waste, and remains to keep PLC in terms of control performance
Advantage.Deficiency (limited memory, program optimization debugging difficulty relative to PLC；Price is high；For
Property difference etc.) native system has more preferable specific aim, uses the most flexible, debugging is convenient, and price is relatively
Low.
