Fig. 6 is the key diagram of the selection picture (key frame) representing equivalents object.
Fig. 7 is the process flow diagram of the selection process (S101, S101b) representing the equivalents object undertaken by the key frame of Fig. 6.Below, the process of Fig. 7 is suitably described with reference to Fig. 6.
The key frame of Fig. 6 has 4 search condition specified windows (the appointment unit of equivalents object, the delineation of worksheet, the delineation of function species, the delineation of variable) and 3 buttons (to rubidium marking assigned picture, determining to variable label assigned picture, mark).
Carried out the selection process of detailed equivalents object by these each operating units, suppress user correctly to specify the omission of the data wanting equivalents thus.
As S201, in the appointment unit window of the equivalents object in key frame upper left, the radio button of the segmentation unit for selecting the program shown in Fig. 4 (a) is set, the segmentation unit of the program shown and selected by radio button (such as, worksheet) corresponding list (such as, the delineation window of worksheet).
As S202, in the delineation window of the worksheet of key frame upper right, in order to draw a circle to approve the element F selecting equivalents object or the worksheet recording variable F, display can select more than one check box from the list of the worksheet of user program.And, using the worksheet selected by check box as delineation condition.
As S203, in the delineation window of the function species of key frame lower-left, in order to draw a circle to approve the function species belonging to element F, display can select more than one check box to selecting the element F of equivalents object.And, using the function species selected by check box as delineation condition.
As S204, in the delineation window of the variable in key frame bottom right, being that value or output valve are possessed in inside to draw a circle to approve this variable, showing the radio button to selecting the variable F of equivalents object to select.And, using the variable species selected by radio button as delineation condition.
Above, in the delineation condition that use 4 windows of S201 ~ S204 explanation are specified respectively, as mutual AND condition (meeting multiple condition) simultaneously, for drawing a circle to approve the element or variable that show rubidium marking assigned picture (S206) described later or variable label assigned picture (S207).Accordingly, by drawing a circle to approve the object that equivalents data are wanted in the selection being prompted to user before list display, thus can operability be improved, and equivalents appointment can be suppressed to omit by delineation condition.
In addition, in order to standby system control device 3 takes over control work from movement system control device 2, the input of equivalents technique or the input value inputted with communication under most cases, the accumulating value of integration/differential or the elapsed time, the count value of counter, the storer of trigger (flip-flop) etc. of timer, as the initial value of the control algorithm after taking over the data that utilize.Therefore, by the delineation window of function species, as long as by the function species of specifying these equivalents as delineation condition, thus the appointment of efficient equivalents object can be realized.
As S205, after pressing the button (to rubidium marking assigned picture), move to the rubidium marking assigned picture as S206 Fig. 8 (a) described later, the list of the functional element in display object complete list 12, by check box from wherein selecting equivalents object, and reflect this result to element F.
As S205, after pressing the button (to variable label assigned picture), move to the variable label assigned picture as S207 Fig. 8 (b) described later, the list of the variable in display object complete list 12, by check box from wherein selecting equivalents object, and reflect this result to variable F.
As S205, after pressing the button (mark determines), terminate S101 (appointment of equivalents object), process is advanced to S102 (being made of object complete list 12).
In addition, Fig. 8 is the key diagram of the selection picture (sprite) representing equivalents object.In this picture, in order to select to want equivalents data (functional element, variable), being prompted to user by generating candidate list, realizing the operation of efficient data selection.
In the rubidium marking assigned picture of Fig. 8 (a), as the list for selecting assimilation object data, the list of the functional element in user program is shown together with the worksheet belonging to this functional element with this element F, by choosing (check) element F hurdle, by every functional element, user is specified as equivalents object (choosing) or as aniso-ization object (without choosing).
In the variable label assigned picture of Fig. 8 (b), as the list for selecting assimilation object data, the list of the variable in user program is shown together with the worksheet belonging to this functional element with the functional element belonging to this variable F, this variable, by choosing variable F hurdle, specifying by every variable uses family is as equivalents object (choosing) or as aniso-ization object (without choosing).
Above, as with illustrated by Fig. 8, functional element or the such tiny unit of variable can be utilized to specify equivalents object, so the program A worked in the transmitter side enforcement division 26 of movement system the control device 2 and program B that works in the receiver side enforcement division 36 of standby system control device 3 can be different in the scope of the data of aniso-ization object.
Accordingly, because the control work of the program A before rebuilding can be continued by movement system control device 2, while the work at real machine of program B after using standby system control device 3 to rebuild confirms, so can improve completeness/security.And, by being switched to the program B of standby system control device 3 after work confirms from the program A of movement system control device 2, thus rebuilding of program can be carried out when not stopping the equipment of workshop system 4, productive raising can be realized.
Fig. 9 is the key diagram of the equivalents process represented in control system.The transverse axis of this key diagram represents the moment, and the longitudinal axis is an example of the variable of equivalents object, represents the score accumulation value in proportion integration differentiation device (PID).Because be score accumulation value, so with time lapse, value rises.Below, be described for following situation: movement system control device 2 is started working, standby system control device 3 is started working after a while afterwards, so the score accumulation value of movement system control device 2 is larger than the score accumulation value of standby system control device 3.
In Fig. 9 (a), when not carrying out equivalents, when the fault due to movement system control device 2 occurs and shifts to standby system control device 3, because can not the score accumulation value of service firing system control device 2, so also directly use the score accumulation value of value very little compared with the score accumulation value of movement system control device 2 and standby system control device 3 after handover.Therefore, because the difference of two score accumulation values is comparatively large so there is violent value change, thus workshop system 4 is affected, so not preferred.
In Fig. 9 (b), when carrying out equivalents, when the fault due to movement system control device 2 occurs and shifts to standby system control device 3, by equivalents, the score accumulation value of movement system control device 2 also can use in standby system control device 3, so there is not the violent value change of score accumulation value, even if carry out systematic evaluation can successfully control workshop system 4 yet.
In present embodiment described above, by the selection picture (sprite) of the equivalents object shown in Fig. 8, utilize functional element or the such tiny unit of variable to specify equivalents object, can select efficiently thus to want equivalents data in redundant system.
And, becoming many situations relative to the candidate number of equivalents object, by specifying by the delineation condition shown in the selection picture (key frame) of the equivalents object of Fig. 6, can draw a circle to approve efficiently before list is carried out to the data of necessity.
