(1) summary processed
Figure 55-1 ~ Figure 55-2 is the process flow diagrams representing in parameter set the example rewriting treatment step.First, the Control System Design device 100 be connected with one of them PLC forming control system, by the method illustrated in embodiment 1, obtains network structure information (step S451) from the control system of carrying out action.Below, this network structure information is called on-line network structural information.
Then, for acquired on-line network structural information, in offline state variation of parameter is edited (step S452), generate off line network structure information.Now, assuming that make 1 network of network parameter be changed.Then, based on the off line network structure information edited out in offline state, calculate routing parameter (step S453).

Return Figure 55-1, the routing parameter be associated by the network selected in step S454 carries out rewriting (step S456), rewrites process and complete in parameter set.
(2) object lesson processed
Due in the above description, the summary of rewriting process in parameter set is described, so be described in detail for the object lesson of this process below.Here, be described for following situation, that is, the routing parameter according to Figure 53-1 ~ Figure 55-4 calculated by embodiment 6 is carried out to the control system shown in Figure 28 of action, o.3 network N between controller to be changed between controller network N o.10.
First, according to the method illustrated in embodiment 1, obtain the on-line network structural information of the control system shown in the Figure 28 carrying out action, and be stored in on-line network structural information maintaining part 116.
Then, according to the method illustrated in embodiment 4, for on-line network structural information, generated by system architecture editorial office 121 and in offline state o.3 network N between controller is changed to network N off line network structure information o.10 between controller, and be stored in off line network structure information maintaining part 122.In addition, according to the method illustrated in embodiment 6, based on the off line network structure information after change, carry out the calculating of routing parameter.Figure 56-1 ~ Figure 56-4 is figure of the routing parameter after the structure modify representing control system.In the 513rd row of Figure 56-1 and the 515th row of Figure 56-2, become respectively by 503 of Figure 53-1 and Figure 53-2 505 in transmission objective network sequence number be the form that the part of " 3 " changes to " 10 ".
Then, on-line network structural information and off line network structure information being compared, there is the network changed in extracting parameter., extract following situation here, that is, between the controller of on-line network structural information, o.10 network N part o.3 to change between controller network N in off line network structure information.
Then, for network N between the controller that existence is changed o.3, the rewriting process of each PLC parameter shown in Figure 55-2 is performed.First, in the control system of carrying out action, the parameter of common website PLC maximum for the website sequence number in the PLC be o.3 connected with network N between controller and PLC ψ (website sequence number 3) is rewritten as new argument.That is, the rewriting process of from the website sequence number 3 of network N common website o.3 " between the controller " to the website sequence number 3 of network N common website o.10 " between the controller " is carried out.
Then, rewrite in the control system of carrying out action, the master station in the network parameter of the admin site PLC be o.3 connected with network N between controller and PLC μ being counted deducts 1.That is, the master station o.3 of network N between controller is counted from " 3 " be rewritten as " 2 ".Thus, in this moment, between controller, network N is o.3 to carry out action under the state be connected with PLC ω with PLC μ, although PLC ψ has carried out physical connection, but is in the state of not carrying out action as the website o.3 of network N between controller.
Then, counting due to the master station in the network parameter of the admin site PLC that is o.3 connected with network N between controller and PLC μ is " 2 " instead of " 1 ", so in this moment, the parameter of common website PLC maximum for the website sequence number in the PLC be o.3 connected with network N between controller and PLC ω (website sequence number 2) is rewritten as new argument.That is, the rewriting process of from the website sequence number 2 of network N common website o.3 " between the controller " to the website sequence number 2 of network N common website o.10 " between the controller " is carried out.
Then, the master station in the network parameter of the admin site PLC be o.3 connected with network N between controller and PLC μ is counted deduct 1.That is, the total website sequence number o.3 of network N between controller is rewritten as " 1 " from " 2 ".Thus, in this moment, between controller, o.3 network N carries out action with the state be only connected with PLC μ, although PLC ω and PLC ψ has carried out physical connection, is in the state of not carrying out action as the website o.3 of network N between controller.
Then, because the master station in the network parameter of the admin site PLC that is o.3 connected with network N between controller and PLC μ counts as " 1 ", so the parameter of the PLC μ of this admin site is rewritten as new argument.That is, rewrite to the website sequence number 1 of network N admin site o.10 " between the controller " from the website sequence number 1 of network N admin site o.3 " between the controller ".Thus, in this timing, between controller, o.10 o.3 network N to change between controller network N, between controller network N o.10 in, carry out action with the state be connected with PLC μ, PLC ω and PLC ψ.The parameter rewriting process of each PLC of Figure 55-2 terminates thus.
Then, the process of rewriting the routing parameter be o.3 associated with network N between the controller that there is change is carried out.Here, o.10, so with this situation, in the routing parameter shown in Figure 56-1 ~ Figure 56-4 again automatically calculated, the routing parameter be o.10 associated with network N between controller is rewritten as because o.3 network N between controller changes to network N between controller.That is, for PLC π, the new routing parameter P π q of write shown in Figure 56-1, for PLC α, the new routing parameter P α q of write shown in Figure 56-2.In addition, owing to there is the network of change not much else, complete so rewrite process in parameter set.
According to the present embodiment 7, there is following effect, that is, when changing network parameter, can will comprise the change of the network parameter of routing parameter, automatically to there is the PLC write of changing.In the prior art, when network parameter changes, need connection control system design apparatus 100 on each PLC carrying out changing, write new setting respectively, very loaded down with trivial details, but in present embodiment 7, there is the effect that can change via the network parameter of network to each PLC.
Embodiment 8
Effective method when embodiment 7 is 1 network change parameter for carrying out in the system of action, in present embodiment 8, illustrates the situation for multiple network change parameter.
Even if when for multiple network change parameter, as long as change application implementation mode in turn 7 for each, the network parameter of each PLC of the change comprising routing parameter just automatically can be rewritten.But owing to sometimes there is the PLC needing repeatedly to rewrite routing parameter, although so rewriting operation is carried out automatically, efficiency is low.Thus, in present embodiment 8, be described for by the Control System Design device carried out in above-mentioned rewriting operation set and Control System Design method.
The structure of Control System Design device used in present embodiment 8 is identical with the structure shown in Figure 54 of embodiment 7.But, in parameter set, rewriting portion 128 has following function, namely, first from distance starting point PLC network farthest, the renewal of the network parameter of routing parameter is not comprised in turn towards starting point PLC, then, from the PLC that distance starting point PLC is nearest, the renewal of routing parameter is carried out in turn towards the PLC of network far away.Thus, the state that cannot communicate during network parameter can be avoided to upgrade.

If for the network selected in step S515, the parameter of the PLC of Figure 55-2 is rewritten process and is completed, then determine whether that there is to the parameter extracted in step S514 the all-network changed all has carried out selecting (step S517).In the situation (situation being no in step S517) of network not selecting all changes, from the network extracted, select the network (step S518) that 1 distance starting point PLC time is far away.Then, return step S516, repeat above-mentioned process, until all select according to the far and near order of the connecting path with starting point PLC there is the all-network changed.In addition, in the situation (situation being yes in step S517) that have selected the network that all existence are changed, the routing parameter carrying out Figure 57-2 rewrites process (step S519).
Be transferred to Figure 57-2, from carried out network parameter and rewritten the PLC that the network that processes is associated, extract the PLC(step S531 needing to rewrite routing parameter).In the PLC extracted, from the PLC that the connecting path remained in off line connecting path maintaining part 125 is shorter, rewrite routing parameter (step S532) in turn.Thus, routing parameter is rewritten process and is completed, and rewrites process and complete in parameter set.

First, extract in the routing parameter of Figure 58-1 ~ Figure 58-4 recalculated, need the PLC rewriting routing parameter.Here, because o.9 o.1 network N between controller to change between controller network N, between controller, o.10 o.3 network N to change between controller network N, so rewrite all routing parameters shown in Figure 53-1 ~ Figure 53-4 comprising the current use of above-mentioned key element.That is, need to write the new routing parameter shown in Figure 58-1 to PLC π, write the new routing parameter shown in Figure 58-2 to PLC α, write the new routing parameter shown in Figure 58-3 to PLC β, write the new routing parameter P μ q shown in Figure 58-4 to PLC μ.
When the write process carrying out above-mentioned routing parameter, in these PLC, with the order the PLC shorter from the connecting path remained in off line connecting path maintaining part 125, rewrite routing parameter., remaining on the off line connecting path in off line connecting path maintaining part 125 here, is the network architecture for editing out in offline state, the connecting path used when calculating routing parameter.Here, because the connecting path of the PLC π directly connected is the shortest, so first write the new routing parameter of Figure 58-1 to PLC π.
Then, with reference to off line connecting path maintaining part 125, the PLC that extraction connecting path is wherein the shortest.The shortest PLC of connecting path is wherein PLC α.Thus, the new routing parameter of Figure 58-2 is then write to PLC α.
In the same manner, connecting path time short PLC is PLC β and PLC μ, writes the new routing parameter of Figure 58-3, write the new routing parameter of Figure 58-4 to PLC μ to PLC β.Thus, rewrite process in the rewriting process of routing parameter and the parameter set of multiple network to complete.
Here, when the method for the PLC application implementation mode in turn 7 for rewriting network parameter, automatically can rewrite the network parameter of each PLC of the change comprising routing parameter, but existence needs the PLC repeatedly rewriting routing parameter sometimes.That is, between write in PLC π reflects controller, o.1 network N changes between controller after network N routing parameter o.9, needs again to reflect to PLC π write o.3 network N between controller is changed to network N routing parameter o.10 between controller.But, by utilizing said method, these routing parameters can be collectively written into, the operation high efficiency change of the routing parameter involved by the change of network parameter write to each PLC can be made.
According to the present embodiment 8, due to the network of network parameter being more than or equal to 2 forming control system in offline state there occurs change when, first from the network far away with the connecting path of starting point PLC, only network parameter is changed in turn, then to start to change routing parameter in turn with the nearlyer person of the connecting path of starting point PLC, so have the effect can concentrating the rewriting carrying out network parameter.
In addition, in above-mentioned embodiment 1 ~ 8, exemplify and describe the situation of Programmable Logic Controller as control device control system connected to the network, but purport of the present invention is not limited thereto.Such as, except Programmable Logic Controller, also can be applied to the control system that numerical control device or movement controller, robot controller equal controller are connected to the network in the same manner.
In addition, above-mentioned Control System Design method can be realized by following method, that is, will be written with the program for the treatment of step by having CPU(central operation treating apparatus) personal computer or the computing machine such as workstation perform.In this case, the CPU(control module of computing machine) perform according to program each treatment process that said procedure generates support method.These programs are stored in hard disk, flexibility (floppy) (registered trademark) disk, CD(Compact Disk)-ROM(Read Only Memory), MO(Magneto-Optical disk), DVD(Digital Versatile Disk or Digital Video Disk) etc. can be undertaken in the storage medium read by computing machine, by being read from storage medium by computing machine and performing.In addition, these programs also can be issued via the networks such as the Internet (communication line).
