In, show a case that selection SwOp3 ladder diagram limb 43 and be put into be performed simultaneously group 61 in (st203).
SW order groups extraction unit 14 for example carries out execution item based on SMT (SATISFIABLE MODULO THEORIES)
Whether the product of part has the judgement of solution.SMT is the arithmetic theory for the mathematical system for indicating specific area, sets theory etc..By
Several SMT solvers can solve the satisfiability decision problem of first-order predicate logic.In addition, SMT includes not only constraint satisfaction
Could, also be included in constraint satisfaction in the case of information from the distribution method to variable.
SW order groups extraction unit 14 confirms interior with the presence or absence of unexplored ladder diagram limb (step in common group 51 of equipment
S38).There are unexplored ladder diagram limb (step S38, Yes), SW order group extraction units 14 are to common
Whether the element of the ladder diagram limb set of equipment is that sky is confirmed (step S33).
In the case of the ladder diagram limb that can be selected in common group 51 interior presence of equipment (step S33, No), SW orders
Group's extraction unit 14 selects 1 unexplored ladder diagram limb (step S34) out of common group 51 of equipment.SW order groups extraction unit 14
Such as the ladder diagram limb 45 of selection SwOp5.
SW order groups extraction unit 14 judge belong to be performed simultaneously group 61 ladder diagram limb 41,43 execution condition with it is selected
Whether the product of the execution condition for the ladder diagram limb 45 selected has solution (step S35).Here SW order groups extraction unit 14 judges
(X0*X1) whether * ((NOT X0)+(NOT X2)) * (NOT X1)=TRUE is true.
(the step in the case where the product of the execution condition of ladder diagram limb 41,43,45 does not have solution of SW order groups extraction unit 14
Rapid S36, No), selected ladder diagram limb 45 is put into other different from group 61 is performed simultaneously and is performed simultaneously group, and from
It is deleted in common group 51 of equipment.
SW order groups extraction unit 14 is the case where having generated and being performed simultaneously 61 different other of group and be performed simultaneously group
Under, judge the execution of the execution condition and selected ladder diagram limb 45 of the generated ladder diagram limb being performed simultaneously in group
Whether the product of condition has solution.Ladder diagram limb 45 is put into having given birth to by SW order group extraction units 14 with solution
At while execution group in.
On the other hand, SW orders group extraction unit 14 is performed simultaneously group not generating and be performed simultaneously 61 different other of group
In the case of, selected ladder diagram limb 45 is put into wherein by execution group while generating new.In fig. 9, it shows selection
The ladder diagram limb 45 of SwOp5 and be put into it is new while execution group 62 in situation (st204, st205).
Then, whether SW orders group extraction unit 14 is empty progress to the element of the ladder diagram limb set with common equipment
Confirm (step S33).If not being sky, SW order groups extraction unit 14 carries out the processing of step S34~S38.
Moreover, in the processing of step S38, there is no not in SW order groups extraction unit 14 is judged as common group 51 of equipment
In the case of the ladder diagram limb of investigation (step S38, No), SW order groups extraction unit 14 is directed to different from common group of equipment 51
The processing of common group of carry out step S31~S38 of other equipment.For example, SW order groups extraction unit 14 for common group 52 of equipment into
The processing of row step S31~S38.
Moreover, in the processing of step S33, if SW order groups extraction unit 14 is judged as the ladder diagram with common equipment
The element of limb set is empty (step S33, Yes), the then life of execution group while making to carry out by SW order groups extraction unit 14
Terminate at processing.
In this way, SW order groups extraction unit 14 is trapezoidal by that will there is a possibility that be performed simultaneously among common group 51 of equipment
Figure limb set is generated as group is performed simultaneously, to be grouped to ladder diagram limb.
By order group extraction unit 14 SW it is sorted be performed simultaneously it is among group, according to the common group of life of identical equipment
At while execution group be the SW order groups that will not be performed simultaneously each other.In other words, according to the common group of generation of identical equipment
Execution group is the SW order groups that will not be performed simultaneously while different.For example, it is common according to equipment to be performed simultaneously group 61,62
Group 51 and generate, therefore to be performed simultaneously group 61,62 be the SW order groups that will not be performed simultaneously.
SW order groups extraction unit 14 in the case where equipment according to figure 7 generates for common group 52 and is performed simultaneously group,
Execution group and execution group while ladder diagram limb 42 comprising SwOp1 while generating the ladder diagram limb 44 comprising SwOp4.
In this way, generate be performed simultaneously group after it is found that SwOp0, SwOp3 are performed simultaneously sometimes, " SwOp0, SwOp3 "
It will not be performed simultaneously with " SwOp5 ".In addition we know, SwOp1 and SwOp4 will not be performed simultaneously.

Presumption.Figure 10 is the figure for illustrating the calculation processing example of maximum scan time.
In fig. 10, it is illustrated that the correspondence of SW orders or HW orders and execution time.In addition, in fig. 10, it is illustrated that
The presumed value of maximum scan time 30.In the case where there is the SW order groups that will not be performed simultaneously, it is believed that SW orders are held
The execution time of longer SW orders group row time makes contributions to the maximum scan time 30.Therefore, time presumption unit 15 is executed
Calculation processing of the time longer SW orders group applied to the maximum scan time 30 will be executed.
For example, the execution time of " the LD X0 " of HW orders is Tld, the execution time of " the AND X1 " of HW orders is Tand.
In addition, if it is Ti that the execution time of " SwOpi " of SW orders, which is described, the execution time of SwOp0~SwOp5 is respectively T0
~T5.In this case, about SwOp0, SwOp3, SwOp5 in common group 51 of equipment, larger one of " T0+T3 " and T5
It is applied to the calculation processing of maximum scan time 30.In addition, about SwOp1, SwOp4 in common group 52 of equipment, T1 and T4
A larger calculation processing for being applied to the maximum scan time 30.
In fig. 10, it is illustrated that the result of calculation of the maximum scan time 30 in the case of (T0+T3) ＞ T5 and T1 ＞ T4.It holds
Row time presumption unit 15 is held the SW order groups' of calculation processing among SW order groups, not being applied to the maximum scan time 30
The row time is set as 0 and calculates the maximum scan time 30.
Execute the calculating that (T0+T3) among (T0+T3) and T5 is applied to the maximum scan time 30 by time presumption unit 15
T1 among T1 and T4 is applied to the calculation processing of maximum scan time 30 by processing.Therefore, time presumption unit 15 is executed by T0
+ T3+T1 is calculated as the execution time of SW orders.
In addition, execute time presumption unit 15 is calculated as HW orders by the total ascent time of the execution time of whole HW orders
Execute the time.Specifically, execute time presumption unit 15 is calculated as HW lives by 4Tld+2Tldi+Tand+Tani+Tori+Tout
The execution time of order.Then, execute time presumption unit 15 by SW orders execute time and HW orders execute adding up to for time
Presumed value of the time as the maximum scan time 30.
