Real time driver develops full text archives and hardware kit; 5, the IEC1131-3 level that place of software of language ControlWorX32 configuration counts the programming of ControlWorX32 configuration software is made to can invent programmed control implement (PLC) defined 5 kinds of programming language. Namely two kinds of text change programming language (IL: Instruction list and ST: Structured text) change programming with two kinds of graphs language (FBD: Functional module chart and LD: Echelon chart) , and programming of a kind of systematism language (SFC: ) of ordinal function chart. IL(instruction list) by a series of order that provide an operation statement in each the instruction expresses composition, of these ordinal instruction great majority and microprocessor grand the instruction photograph of assembler design language is compatible. This is programming of a kind of adaptable means, but to doing not have programming the industrial user of experience is told, this kind of programming means has been confirmed to be special trouble and prolonged. Build complex application to tell to compose, in fact IL(instruction list) can provide powerful basic function for this. However, in the applied program that in small-sized and critical condition runs, optimizing code is very important. Pursue 3 it is one uses IL(instruction list) the example of process designing, variable RUN_TIMER is become by the definition TON type. The sampling cycle of last definition is 1 second, variable Run_pluse will by set, effective output will make electric machinery happening rotates. Graph 3 use IL(instruction list) the text of example ST(structuralization of process designing code) it is one sort is like the advanced programming at Pascal language. If symbolic address is used, ST(structuralization text) the program is similar to a sentence, means of this kind of process designing special the study that is helpful for a novice. Text of structuralization of algorithmic to complex mathematical computation task and control ST() it is a kind of wonderful programming language. ST(structuralization text) the language uses programming rise very simple, and unlike the LD(echelon chart that has lengthy code) or) of chart of FBD(function module. Pursue 4 it is one introduces ST(structuralization text version) the example of the partial code that the language writes programming. Variable TIMER is regarded as TON type by the definition, use a timer of 1 second to undertake initialization. After times time arrives, criterion pulse is variable will set. Next, pulse variable makes variable tally increases, consequently the setting exports variable output 1 when for true. This kind of loop goes down proceed, till all output variable is installed afresh. Graph 4 introduce ST(structuralization text version) the chart of module of example FBD(function of process designing code) the language allows programming industrial user uses a graph to change functional module to develop applied program with the means of configuration, these functional module can be extracted from inside library of module of IEC standard function. Be in dispersive model in controlling a system, control engineer uses chart of FBD(function module) the configuration that undertakes controlling a system will more handy. Pursue 5 it is one uses chart of FBD(function module) programming the example of language process designing. Variable Start will start electric machinery move. AND function module will pass power transmission source to TON of module of the first timer. After passing 1000ms, output is variable O1 general set, at the same time module of the 2nd timer will by initialization. This kind of loop goes down proceed, be installed till variable StartOver, accordingly, restoration order relies on AND module. LD(echelon chart) the way of PLC process designing that language and people place are familiar with programming is same, it used traditional relay and coil. Means of this kind of process designing basically faces the disperse application that controls a system. However, the echelon chart editor of IEC1131-3 standard allows functional module to embed go in echelon chart code, so that establish more quick procedure,control application. For example, controlWorX32 configuration software had provided this kind of built-in function, for this, more and more final industry users will come on the process designing way that from traditional relay logistic chart changes the functional module chart that has the IEC1131-3 level that escalates a function gradually. Pursue 6 it is one uses LD(echelon chart) programming the example of language process designing. However, below this kind of circumstance, foregoing FBD function components had been baled the genetic function module that is called CQ into (DBF) . This module has been succeeded compositive in echelon chart. Chart of SFC(ordinal function) the descriptive method that changes to produce a process to offer a chart, it is OK that this means this method in breaking up a paragraph of program a logistic order, go. Pass direct link, the constituent unit that can accord with measure and mutual the changeover between. Graph 5 use chart of FBD(function module) the example of process designing pursues 6 use LD(echelon chart) the example of process designing uses direct link method, in chart of SFC(ordinal function) in be used at coordinating place connective measure and move relation by the code main body of process designing. Or many operations module can related to a measure couplet. When a measure is in mobile condition, related to this measure the operation of couplet will be carried out, and rely on place definitive operation. This kind of operation can become a Boer variable, in the meantime, undertake re-edit to code likely, so that can be in,a job of code main body that has detailed name gets executive in the watch. Below this kind of circumstance, the name that the file name that has tabulation of labour of code main body can regard place as the operation will use. Graph 7 use chart of SFC(ordinal function) the example of process designing is in chart of SFC(ordinal function) in, one arrives from a measure the produces process terminal move condition of another measure can get a description. If one transfers a condition to become true (TRUE) , and once again when follow-up perhaps measure becomes mobile state, the measure in front can get executive. In chart of FBD(function module) or LD(echelon chart) in, condition of this kind of move is not a Boer variable it is a direct connective Boer expression. In chart of SFC(ordinal function) in process designing above all by connective be one calls SFC(order functional chart) network. Chart of ordinal function of a SFC() the network always must have an initialization move, and organize unit when the program (the first measure after POU) is started can be carried out above all. The functional module that parallel perhaps has branch structure can insert chart of SFC(ordinal function) go in the network. In chart of SFC(ordinal function) in code main body, can use asterisk and bracket to insert relevant annotate statement among them. Pursue 7 it is one uses chart of SFC(ordinal function) the example of process designing. 6, if the application in producing a process to control pursues 8 for sketch map of simple odd loop closed-loop control. Use this case, how do we write study functional module in ControlWorX32 configuration software, with etc the method of project of language design project mixes a few programming knowledge. We will control management to build for the process a series of functional module. After the deviation between set value and process measured value controls algorithmic operation through PID, its output is worth immediate effect to control variable at the process. Graph block diagram of closed-loop control of 8 odd loop 1. Project of the project that start above all you must build a new project project. For this, from entree sheet " file " the choice below menu " build project project " command, criterion casing of project project pattern plate will appear.
