Embodiment
Relevant characteristics and implementation of the present invention, existing conjunction with figs. is described in detail as follows most preferred embodiment.
Please refer to Fig. 1, be system block diagrams of the present invention, include menu interface display module 10, program instruction data storehouse 20, logic judgment module 30, menu instruction removing module 40 and ladder figure generation module 50.
Menu interface display module 10, in order to the operation interface that shows that a plurality of menus instruct, and the menu instruction is chosen the menu instruction according to the demonstration of predetermined instruction editor series arrangement in regular turn so that the user to be provided, and after the user has edited the menu instruction, show the ladder figure and list programmed instruction.
Program instruction data storehouse 20, be connected with menu interface display module 10, and store a plurality of programmed instruction, the menu of choosing according to the user instructs, read corresponding programmed instruction, and the menu instruction is an one with programmed instruction, wherein programmed instruction roughly can be divided into elementary instruction and application instruction, elementary instruction includes: general instruction, output order, timer, counter and master control instruction or the like, and application instruction includes: circuit controls instruction, high number processing instruction, four fundamental rules logic instruction and transmission comparison order or the like.
Menu instructs removes module 40, is connected with menu interface display module 10, in order to the setting content of removing menu instruction, and reverts to the not preceding state of editor, resets the content of menu instruction so that the user to be provided.
Ladder figure (ladder diagram) generation module 50, be connected with menu interface display module 10, program instruction data storehouse 20, after the user has edited the menu instruction, according to programmed instruction, produce corresponding ladder figure, and by 10 demonstrations of menu interface display module, to provide the user to carry out program editing debug operation, common electromechanical assembly includes in the switchboard: button, relay, switch, counter and timer or the like and the basic symbol of ladder figure is according to controlling automatically.
The user is sent to execution in the programmable logic controller (PLC) 60 with the programmed instruction of listing after the intact program of menu editing system inediting, can control output device.
Please refer to Fig. 2, be flow chart of steps of the present invention, at first, the user chooses menu instruction (step 200); Editing system instructs to program data base according to menu and reads corresponding programmed instruction (step 201), and the menu instruction is man-to-man corresponding relation with programmed instruction; Next, the logical relation (step 202) of determining program instruction, via the logical relation of editing system determining program instruction, if when the logical relation of programmed instruction is mutual exclusion, it is the menu instruction of mutual exclusion that the user can't choose with its logical relation again; According to logical relation, show a time selectable menu instruction (step 203), to avoid the problem of logical program mistake on the program editing.
Judge whether to remove the setting content (step 204) of menu instruction, when desiring to update the menu instruction, can remove module 40 by the menu instruction and remove the setting content that menu instructs, and get back to step 200 as if the user.
Judge whether to finish program editing operation (step 205), after if the correlation parameter of menu instruction is set and has all been shown, that judges whether the user choose menu operation interface finishes the editting function key, if the user still need carry out the program editing operation, promptly get back to step 200, continue the correlation parameter of menu instruction and set.
After confirming to finish editor, editing system can show the ladder figure and list programmed instruction (step 206), the user is by the ladder figure of demonstration and the contrast relationship of programmed instruction, whether fast browsing device action order meets the requirements, after having confirmed that the device action order is errorless, next, the user only needs the programmed instruction of listing is sent to execution in the programmable logic controller (PLC) 60, can carry out the control operation of output device.
Please refer to Fig. 3, be operation interface synoptic diagram of the present invention, at first, the user chooses and will build the instruction type (high-speed counter or PID control) of putting, choose high-speed counter and click " next step " function key, to carry out parameter setting, please refer to Fig. 4, the parameter setting content includes the counting pattern, the counter numbering, the counter input, counter setting value and counting direction, and every menu instruction shows according to predetermined instruction editor series arrangement, be that its parameter setting content is arranged demonstration according to logical order, to avoid taking place the situation of missing parameter setting or programmed instruction logical program mistake.
Wherein, the parameter setting of counting pattern partly is single point selection function, be that the user only can choose a kind of counting pattern (1 1 input, 1,2 inputs or 2 input mutually mutually mutually), next set counter numbering, conditional, counter input, counter setting value in regular turn.
Please refer to Fig. 5, counting direction is a point selection function, click " upwards counting " or " counting downwards " the user after, just can enter down one deck menu instruction line parameter of going forward side by side sets, if before not clicking " counting makes progress " or " counting downwards " menu instruction, instruction of one deck menu can't be carried out parameter setting under it, i.e. the part that dotted line is represented among Fig. 4, editor's setting means can be avoided the logical program error situations between programmed instruction so in regular turn.
In addition, when the user desires to reset the menu instruction, can click " removing setting value " function key, the menu instruction promptly reverts to the not preceding state of editor, next, click " next step " function key and continue the program editing operation, please refer to Fig. 6, be menu instruction editing operation of the present invention interface synoptic diagram, the parameter setting content that shows each menu instruction respectively, after the user chooses " DHSCS " this instruction project, can enter down one deck menu " counter reaches action and sets " and carry out the parameter setting of device contact and the parameter setting of " fiducial value ", the required setup parameter value of this instruction can be listed one by one by menu operation interface, therefore, the problem that missing parameter was set when the user can not edit this instruction, thus the correctness and the fiduciary level of edit routine promoted.
Please refer to Fig. 7, be demonstration ladder figure of the present invention and the synoptic diagram of listing programmed instruction, after the user has edited program, and click " finishing " function key, editing system shows staircase chart immediately or lists corresponding programmed instruction, whether node and parameter value that the user can be once more sets by the inspection of ladder figure be correct, if after confirming correctly, next, the user only needs the programmed instruction of listing is sent to execution in the programmable logic controller (PLC) 60, can carry out the control operation of output device.
The System and method for of the program editing by this programmable logic controller (PLC), allow the user pass through easy menu operation interface, can carry out the program editing operation, and the problem of occurrence logic program error can avoid editor command the time, reach simple and easy study and promote the correctness of program editing and the purpose of fiduciary level.
Though the present invention with aforementioned preferred embodiment openly as above; right its is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, therefore scope of patent protection of the present invention must be looked the protection domain that this instructions appending claims defined and is as the criterion.
