Below, the step of having utilized the routing parameter of setting as stated to carry out the data transmission is carried out simple declaration.At first, network N PLC 10-3 o.1 sends the data of sending to network N PLC 10-13 o.3 based on routing parameter.That is, be " 3 " according to transmitting the objective network sequence number, the relaying objective network is " 1 ", relaying targeted sites sequence number is " 4 " such setup parameter, sends data.Thus, o.1 send via network N from the data of PLC 10-3 to PLC 10-4 (have network N o.1 in as the PLC of the communication unit 1Ns4 of website 4).

If the communication unit 1Ns4 of this PLC 10-4 receives data; Then because the transmission target is network N PLC 10-12 o.3; So, via communication unit 2Ns1 and network N o.2, be that PLC 10-13 sends to the relaying targeted sites sequence number 4 of relaying objective network No.2 with reference to routing parameter.In PLC 10-13, because the data that receive are the data of sending to network N PLC 10-12 o.3, so o.3 send to PLC 10-12 via communication unit 3Ns5 and network N.Thus, the data toward journey transmit completion.

Below, explain that the network N PLC 10-12 o.3 as request target transmits data conditions to the network N PLC 10-3 o.1 as request source, i.e. the situation of the data of return transmission.In this case, network N PLC 10-12 o.3 is that network N PLC 10-3 o.1 sends data to transmitting target.O.3, these data arrive PLC 10-13 via network N.In PLC 10-13; Because the transmission target of these data is for transmitting the PLC 10-3 of objective network No.1; So, be that " network N o.2 ", relaying targeted sites sequence number transmit data for the network N PLC 10-4 o.2 of " 1 " to the relaying objective network with reference to routing parameter.

Because in network N PLC 10-4 o.2, receiving with network N PLC 10-3 o.1 is the data that transmit target, thus via be installed on the same substrate communication unit 1Ns4 and network N o.1, be PLC 10-3 transmission to transmitting target.Then, PLC 10-3 receives the data from network N PLC 10-12 o.3.Thus, the data of return transmit and accomplish.

Then; Owing to be that master station in the network parameter of PLC μ counts with the admin site PLC that o.3 is connected of network N between controller is " 2 " rather than " 1 "; So will be that the parameter of PLC ω (website sequence number 2) is rewritten as new argument with the maximum common website PLC of website sequence number among the PLC that o.3 network N between controller is connected at this constantly.That is the rewriting of, carrying out from " the website sequence number 2 of network N common website o.3 between controller " to " the website sequence number 2 of network N common website o.10 between controller " is handled.

Then, will be that master station in the network parameter of PLC μ counts and deducts 1 with the admin site PLC that o.3 network N between controller is connected.That is, the total website sequence number o.3 of network N between controller is rewritten as " 1 " from " 2 ".Thus, at this constantly, o.3 network N moves with the state that only is connected with PLC μ between controller, though PLC ω and PLC ψ have carried out physical connection, is in not as website and the state that moves o.3 of network N between controller.

Then and since with controller between the admin site PLC that o.3 is connected of network N be that master station in the network parameter of PLC μ counts and is " 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 controller " from " the website sequence number 1 of network N admin site o.3 between controller ".Thus, at this regularly, o.10 o.3 network N change between controller network N between controller, between controller network N o.10 in, to move with PLC μ, PLC ω and the state that PLC ψ is connected.The parameter of each PLC of Figure 55-2 is rewritten the processing end thus.

Then, rewrite with the controller that has change between the processing of the routing parameter that o.3 is associated of network N.Here because o.10 o.3 network N change between controller network N between controller, so follow this situation, in the routing parameter shown in Figure 56-1～Figure 56-4 that calculates automatically again, be rewritten as with controller between the routing parameter that o.10 is associated of network N.That is,, write the new routing parameter P π q shown in Figure 56-1,, write the new routing parameter P α q shown in Figure 56-2 to PLC α to PLC π.In addition, because the network of existence change not much else, finish dealing with so rewrite in the parameter set.

According to this embodiment 7, have following effect, that is, when the change network parameter, can automatically write comprising the change of routing parameter at interior network parameter to the PLC that has change.In the prior art, when network parameter changes, need be on each PLC that changes connection control system design apparatus 100; Write new setting respectively; Very loaded down with trivial details, but in this embodiment 7, have the effect that can change the network parameter of each PLC via network.

Embodiment 8

Embodiment 7 is to effective method under the situation of 1 network change parameter in the system of having moved, and in this embodiment 8, the situation to a plurality of network change parameters is described.

Even under the situation of a plurality of network change parameters,, just can automatically rewrite the change that comprises routing parameter network parameter at each interior PLC as long as change application implementation mode in order 7 to each.But, because the PLC of routing parameter need be repeatedly rewritten in existence sometimes, so though the rewriting operation is carried out automatically, efficient is low.Thus, in this embodiment 8, to concentrating the Control System Design device and the Control System Design method of carrying out to describe above-mentioned rewriting operation.

The structure of the Control System Design device that in this embodiment 8, uses is identical with the structure shown in Figure 54 of embodiment 7.But; Rewriting portion 128 has following function in the parameter set; Promptly; At first, then, begin to carry out in order the renewal of routing parameter from the PLC nearest towards the PLC of network far away apart from starting point PLC from beginning not comprise the renewal of routing parameter in order at interior network parameter towards starting point PLC apart from starting point PLC network farthest.Thus, the state that can avoid network parameter can't communicate by letter in upgrading.

(1) summary of handling

Figure 57-1～Figure 57-the 2nd, the process flow diagram of an example of rewriting treatment step in the parameter set of a plurality of networks of expression.At first, with the Control System Design device 100 that one of them PLC that constitutes control system is connected, obtain on-line network structural information (step S511) from the control system of moving.Its result is stored in the on-line network structural information maintaining part 116.

Then,, under off-line state, parameter modification is edited (step S512) to the on-line network structural information that obtains, its result as off line network structure information storage in off line network structure information retaining section 122.At this moment, suppose changing more than or equal to 2 network of network parameters.Then, be based on the off line network structure information that edits out under the off-line state, carry out the computing (step S513) of routing parameter.

Then, the on-line network structural information that will in step S511, obtain and compare in the off line network structure information that step S512 inediting goes out, there is the network (step S514) of change in extracting parameter.

Then; From the network that is extracted; With reference to being stored in the off line connecting path information in the off line connecting path maintaining part 125; Select 1 connecting path network (step S515) farthest with starting point PLC, the parameter to each PLC in the selected network shown in the execution graph 55-2 is rewritten and is handled (step S516).In addition,, the parameter of this PLC in embodiment 7, is illustrated because rewriting to handle, should explanation so omit.

Whether if to the network of in step S515, selecting, the parameter of the PLC of Figure 55-2 is rewritten and is finished dealing with, then judge to exist the all-network of change all to carry out selecting (step S517) to the parameter that in step S514, extracts.Do not selecting from the network that extracts, to select 1 under all situation that have the network of change (in step S517, being situation not) apart from PLC network far away of starting point (step S518).Then, return step S516, repeat above-mentioned processing, until to the all-network that has change according to all selecting with the far and near order of the connecting path of starting point PLC.In addition, selecting to carry out the routing parameter rewriting processing (step S519) of Figure 57-2 under all situation that have the network of change (situation) for being in step S517.

Be transferred to Figure 57-2, from rewriting the PLC of the network associated of handling with having carried out network parameter, extraction needs to rewrite the PLC (step S531) of routing parameter.In the PLC that extracts, the short PLC of the connecting path from remain on off line connecting path maintaining part 125 begins to rewrite in order routing parameter (step S532).Thus, routing parameter is rewritten and is finished dealing with, and rewrites in the parameter set and finishes dealing with.

(2) object lesson of handling

Owing in above-mentioned explanation, record and narrate, so the following object lesson that is directed against this processing at length describes to rewriting the summary of handling in the parameter set of a plurality of networks.Here; Describe to following situation; Promptly; O.1, o.9 the control system shown in Figure 28 of moving for the routing parameter with Figure 53-1～Figure 53-4 of calculating through embodiment 6 changes between controller network N with network N between controller, and o.10 o.3 network N between controller changed between controller network N.

At first, the method according to explanation in the embodiment 1 obtains the on-line network structural information of the control system shown in Figure 28 of moving, and is stored in the on-line network structural information maintaining part 116.

Then; Method according to explanation in embodiment 4; By system architecture editorial office 121 make respectively under the off-line state with controller between network N o.1 change between controller network N o.9, with controller between network N o.3 change to network N off line network structure information o.10 between controller, be stored in the off line network structure information retaining section 122.In addition, according to the method for explanation in the embodiment 6, carry out the calculating of routing parameter based on off line network structure information after changing.Figure 58-1～Figure 58-the 4th, the figure of the formation routing parameter after changing of expression control system.

Then, online network structure information and off line network structure information are compared, there is the network of change in extracting parameter., extract following situation here, that is, between the controller of on-line network structural information network N o.1, the part of No.3 in off line network structure information, change to respectively between controller network N o.9, No.10.

Then, to network between each controller that has change, the parameter of each PLC shown in the execution graph 55-2 is rewritten and is handled.That is, at first o.1, implement the parameter rewriting of each PLC and handle, then, to network N between the controller that has change o.3, implement the parameter of each PLC and rewrite processing to network N between the controller that has change.

Then, as follows, be implemented in shown in Figure 57-2 with the controller that has change between network N o.1, the rewriting of the routing parameter that is associated of No.3 handles.

At first, extract in the routing parameter of the Figure 58 that recalculates-1～Figure 58-4, need to rewrite the PLC of routing parameter.Here, because o.9 o.1 network N change between controller network N between controller, o.10 o.3 network N change between controller network N between controller, so rewrite all routing parameters shown in Figure 53-1～Figure 53-4 of the current use that comprises above-mentioned key element.That is, need write the new routing parameter shown in Figure 58-1, write the new routing parameter shown in Figure 58-2, write the new routing parameter shown in Figure 58-3, write the new routing parameter P μ q shown in Figure 58-4 to PLC μ to PLC β to PLC α to PLC π.

Carrying out writing of above-mentioned routing parameter when handling, in these PLC,, rewrite routing parameter with the order that the short PLC of the connecting path from remain on off line connecting path maintaining part 125 begins., remaining on the off line connecting path in the off line connecting path maintaining part 125 here, is to the network architecture that under off-line state, edits out, the connecting path that when calculating routing parameter, uses.Here, because the connecting path of direct-connected PLC π is the shortest, so at first write the new routing parameter of Figure 58-1 to PLC π.

Then, with reference to off line connecting path maintaining part 125, extract the shortest PLC of connecting path wherein.The shortest PLC of connecting path wherein is PLC α.Thus, then write the new routing parameter of Figure 58-2 to PLC α.

Identical ground, connecting path time short PLC is PLC β and PLC μ, writes the new routing parameter of Figure 58-3 to PLC β, writes the new routing parameter of Figure 58-4 to PLC μ.Thus, the rewriting of routing parameter handle and the parameter set of a plurality of networks in rewrite and finish dealing with.

Under situation, can automatically rewrite the change that comprises routing parameter network parameter, but the PLC of routing parameter need be repeatedly rewritten in existence sometimes here, at each interior PLC to the method for the PLC application implementation mode in order 7 of rewriting network parameter.That is, in PLC π, write reflected controller between network N o.1 change between controller behind the network N routing parameter o.9, need once more to PLC π write reflected controller between network N o.3 change to network N routing parameter o.10 between controller.But, through utilizing said method, can these routing parameters be collectively written into, can be so that the operation high efficiency that the change of the routing parameter that the change of network parameter is related writes to each PLC.

According to this embodiment 8; Because the network of network parameter more than or equal to 2 of formation control system has taken place under the situation of change under off-line state; At first from beginning only to change in order network parameter with the connecting path of starting point PLC network far away; Then to begin to change in order routing parameter, so have the effect that to concentrate the rewriting of carrying out network parameter with the nearer person of the connecting path of starting point PLC.

In addition, in above-mentioned embodiment 1～8, give an example the situation of the control system that Programmable Logic Controller is formed by connecting as control device and network has been described, but purport of the present invention is not limited thereto.For example, except Programmable Logic Controller, also can be applied to the control system that numerical control device or movement controller, robot controller equal controller and network are formed by connecting identically.

In addition, above-mentioned Control System Design method can realize through following method, that is, the program that has write treatment step carried out by computing machines such as personal computer with CPU (central arithmetic processing apparatus) or workstations.In this case, the CPU of computing machine (control module) carries out each treatment process that said procedure generates the support method according to program.These procedure stores are in the storage medium that 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 read by computing machine, through from storage medium, being read and carried out by computing machine.In addition, these programs also can be issued via networks such as the Internet (communication line).
