Brief description of the drawings
Fig. 1 is the structural representation of ladder diagram online editing system；
Fig. 2 is the flow chart that code realizes module.
Embodiment
Illustrate the embodiment of the present invention below in conjunction with accompanying drawing.
As shown in figure 1, ladder diagram online editing system includes：Code realizes module and interface operation module, interface operation
Module includes：LD matrix management module, document management module and LD matrix editor modules.LD matrixes are the contracting of ladder diagram matrix
Write.
As shown in Fig. 2 code realizes that the workflow of module is as follows：
Step 1：Collect interface graphical information；
Step 2：Start to calculate；
Step 3：Judge whether present networks enable, if "Yes", into step 4；If "No", into step 13, terminate
Calculate；Here present networks refer to that code realizes the logical network of the pseudo- compiling of module, it is necessary to which enabling this network could be carried out
Programming operation below；
Step 4：Judge whether current input is " sky "；
Step 5：The result (true/false, it is considered in parallel) of design conditions front nodal point；
Step 6：Calculate the result (true/false) of postjunction；
Step 7：Determine whether that last in row is inputted；If "No", into step 8；If "Yes", into step
9。
Step 8：Next input is redirected, subsequently into step 4；
Step 9：According to result after output front nodal point state computation output；
Step 10：Determine whether last column；Enter step 12 if "Yes", if "No", into step 11.
Step 11：First input of next line is redirected, subsequently into step 4.
Step 12：The destination object of output condition association is enabled/disabled according to checkout result.
Step 13：Terminate to calculate.
After code realizes the work of module, the editing of one section of new ladder diagram is completed, corresponding CSV texts are generated
Part.
LD matrix management modules：For setting current LD matrixes title, the different LD matrixes of switching display, preservation/deletion to work as
Preceding LD matrixes, all LD matrixes of deletion, the current LD matrixes of enable/disability, concrete function are as shown in Figure 2.Delete equal during LD matrixes
Have whether dialog box prompting determines to delete corresponding LD matrixes, loss of data is caused with anti-misoperation.
Document management module：For realizing loading/preservation/refreshing csv file, setting the functions such as csv file name.Refresh work(
All csv files under catalogue can be obtained, convenient selection corresponding document is loaded into.By dialogue during loading/preservation csv file
Frame indicates current state.Filename is checked during loading/preservation, if filename length is more than 18 characters or bag
Containing forbidden character, or the file to be loaded into is not present, then prompting can not be preserved.
LD matrix editor modules：Realize to edit operations such as insertion, the deletions of LD matrixes.It may be inserted into input and output section
Point, and node type and condition etc. can be selected.Abbreviation " LD " refers to ladder diagram.
LD matrixes editor module provides 7 kinds of input conditions：Straight line (Link), normally opened (Normally Open), normally closed
(Normally Closed), delay open (On Delay), delay and close (Off Delay), rising edge triggering (Positive
Edge), trailing edge triggering (Negative Edge).Wherein rising edge need to coordinate normally opened/normally closed node to make with trailing edge triggering
With.
The state that revocation function can be preserved with destruction operation to last time.For security consideration, unsaved LD matrixes are forbidden
The overall situation is enabled, while after global enable, forbidding editing LD matrixes, corresponding operating has prompt message.
Expansible input and output matrix；
1) expansible the number networks；
2) MIMO function can be realized；
3) whether each LD matrixes can be separately configured enables, while can also control whether whole LD groups enable；
4) input/output can select DI/DO and intermediate variable, program variable respectively；
5) a number of DI/DO passages are predefined, number of channels can extend；
6) a number of intermediate variable is predefined, can be used in input/output condition；
7) comprising 4 kinds of output conditions：(Direct) is directly exported, output (Inverted), set (Set) is negated, resets
(Reset)；Support revocation and recovery operation.
Use case：
Document management module is updated and worked as by being loaded into csv file or LD matrix editor modules in operation interface
Preceding LD matrixes, it is global after preservation to enable.LD matrixes editor module carries out corresponding operating to DI in operation interface afterwards, and
Monitor corresponding DO states.When being operated to DI, code realizes module in running background, while monitoring whole LD in main interface
The running situation of network.
