This development support device 6 creates a user program executed by a PC such as a ladder program and transfers it to each of the PCs 1 to 4 via the connection cable 7.
It has a U 61, a system program memory 62, an external storage device 63, an output device 64 such as a display, an input device 65 such as a keyboard, an internal memory 66, and an interface 67.

The CPU 61 functions as a program creating means and a program transferring means by executing the system program stored in the system program memory 62, and creates a user program based on the ladder circuit or the like input by the input device 65. , Functioning as program transfer means to perform program transfer processing shown in FIG. 4 described later. It should be noted that when a user program is created, the identification number of the program that matches the node number of the transfer destination PC is registered in each user program by a ladder circuit described later.

The external storage device 63 stores the user program having the identification number created by the CPU 61.

On the side of the CPU unit 11 of the PC 1,
It is generally configured and has a microprocessor 11a.
, I / O memory 11b, system program memory 11c, work memory 11d, user program memory 11e, and interface 11f are connected by a bus 11g.

Then, in the work memory 11d,
As with the other PCs 2 to 4, the node number “001” in the PC network is registered in advance as the identification number of the PC 1.

FIG. 3 shows an identification number registration circuit R for registering the identification number of the program in each user program when the user program to be transferred to each PC in the development support apparatus is created.

The identification number registration circuit R is incorporated in the user program when the CPU 61 creates the user program, and the command word "PRTCT" indicating the registration of the identification number of the program and each user as the identification number of the program. It is composed of an operand "000" in which the node number of the transfer destination PC of the program is set.

The identification number registered in the user program by the identification number registration circuit R is not limited to the collation processing with the identification numbers of the PCs 1 to 4 at the time of program transfer, which will be described later. Each PC 1-4
When the user program is transferred to and stored in the user program memory in each of the PCs 1 to 4, it can also be used as a password for reading the user program.

Next, a program transfer process in the development support apparatus of the first embodiment having the above-mentioned configuration will be described.

FIG. 4 shows a program transfer process in the development support apparatus of the first embodiment configured as described above.

When the program transfer process is started (step 100), first, the CPU 61 of the development support device 6 internally stores, from the external storage device 63, the user program to be transferred to the PC among the user programs created as described above. The transfer destination P is loaded in the memory 66 and is also based on the node number of the transfer destination PC designated as the transfer destination.
A communication path is established with C via the connection destination PC 1 (step 110). That is, for example, in FIG. 1, when the PC 3 having the node number “003” is designated as the transfer destination PC, the development support apparatus 6 establishes a communication path with the transfer destination PC 3 via the connection destination PC 1.

Next, the CPU 61 of the development support device 6 accesses the work memory of the CPU unit of the transfer destination PC 3 and assigns the node number which is the identification number of the transfer destination PC 3 registered in advance in the work memory. At the same time as reading (step 120), the internal memory 6 of the development support device 6 is read.
The identification number registered in the user program to be transferred to the transfer destination PC 3 loaded in 6 is read (step 130), and the node number of the transfer destination PC 3 matches the identification number of the user program to be transferred. It is checked whether or not there is (step 140).

As a result, when the node number of the transfer destination PC 3 and the identification number of the program to be transferred match (step 140 "Y"), the CPU 61 matches the node number to the transfer destination PC 3 concerned. The user program having the identified identification number is transferred (step 150) and the transfer process is terminated (step 170) while the transfer destination P is transferred.
If the node number of C3 and the identification number of the program to be transferred do not match (step 140 "N"), an error message indicating that the collation does not match is displayed on the output device 64 such as the display of the device 6 (step 140). 160) and terminates the transfer process (step 170).

Therefore, according to the first embodiment, after the communication path with the transfer destination PC is established and before the user program is transferred to the transfer destination PC, the node number of the transfer destination PC and the program to be transferred are identified. It is determined whether or not the numbers match, and if they match, the user program is transferred to the transfer destination PC. Therefore, a human error of an operator who is not familiar with the system during the program transfer process Therefore, it is possible to perform an accurate program transfer process intended by the designer, and prevent erroneous transfer of programs, overwrite errors, and the like.

In the first embodiment, the node number is adopted as the identification number of each PC, and the node number of the transfer destination PC is registered as the identification number of the user program to be transferred. Although it has been described that the program is transferred only when the number and the identification number of the program to be transferred match, the present invention is not limited to this.

That is, an identification number other than the node number of each PC may be adopted as the identification number of each PC, and the identification number of the transfer destination PC and the identification number of the program to be transferred need to match. Instead, some kind of relationship or correspondence may be provided.

In the first embodiment, the node number registered in the work memory of each PC has been described as the identification number of each PC. However, when the identification number of each PC cannot be registered in the work memory, The password command of the program registered in the program stored in the memory of each PC may be used as the identification number of each PC. In this case, the development support device accesses the program of the memory after establishing the communication path with the transfer destination PC, reads the password command into the device, and identifies the password command and the identification number of the program to be transferred. Are checked, and if they correspond, the program is transferred to the transfer destination PC.

It is a table that is registered in advance by linking it with an identification (ID) number such as a node number, and is stored in the same directory such as the external storage device 63 in which each user program file to be transferred to each PC 1 to 4 is stored. It is a thing.

In the directory of the external storage device 63, user programs created by this device are stored corresponding to their file names, and user programs other than the transfer target of this time are also stored. .

Next, the program transfer processing of the development supporting apparatus and the like according to the second embodiment having such a configuration will be described with reference to the drawings.

FIG. 6 shows a program transfer process in the development support device.

First, the directory of the external storage device 63 in which the file of the user program created by this device is stored is designated by the input device 65 as the directory designating means, and the directory name is entered in the development support device 6. Then, (step 200), in this development support device 6, the CPU 61 functions as a program transfer means to read the program file name stored in the directory from the external storage device 63, and the file name is shown in FIG. Based on whether or not the program file to be transferred is stored in the designated directory of the external storage device 63, it is determined whether or not it is registered in the link table T shown (step 210).

If it is determined that the program file to be transferred is not stored in the designated directory of the external storage device 63 ("N" in step 210), the program transfer process is terminated while the transfer is completed. When it is determined that the program file to be stored is stored (step 210 “Y”), the program file is read from the external storage device 63 (step 220), and the file name of the read program file is shown in FIG. Transfer destination P by referring to the linked table T shown

Next, the CPU 61 of this development support device 6
Performs a connection process with the connection destination PC 1 to which this apparatus is connected via the connection cable 7 to establish a communication path (step 240), and subsequently uses the transfer source address as the identification number of the development support apparatus, and , The transfer destination address is used as the identification number of the transfer destination PC, and the transfer request for the read program file is sent to the connection destination PC 1 (step 25).
0).

If the transfer request is permitted by the connection destination PC 1 (step 260 "Y"), the transfer source identification number is used as the development support device identification number, and the transfer destination identification number is used as the transfer destination PC. The program file with the identification number of is transferred to the connected PC (step 27).
0), if the transfer cannot be performed normally (step 280)
"N"), while the transfer is repeated again (step 27)
0), if the transfer was successful (step 280)
"Y"), return to the above step 210, judge whether or not there is a program file to be transferred in the directory (step 210), and if there is a program file to be transferred, perform the same processing as above. repeat.

FIG. 7 shows the program transfer processing in the connection destination PC 1.

In the connected PC 1, first, the development support device 6
The transfer destination identification number in the program file sent from the server is checked (step 300), and it is determined whether or not the transfer destination identification number is addressed to its own node (step 310).

If it is not addressed to its own node (step 310 "N"), the program file to be transferred is transferred to the PC indicated by this transfer destination identification number (step 320), and then developed from the transfer destination PC. The response data sent to the support device is received (step 330), and the received response data is sent to the development support device 6
(Step 340) and the process at the connection destination PC ends.

On the other hand, when the transfer destination identification number is addressed to its own node (step 310 "Y"), the transfer destination PC will be described in detail with reference to FIG. 8 like the other PCs 2 to 3. Program reception processing in step (35)

Response of “program writing failure” is sent to the development support device 6
(Step 357), and the receiving process at this transfer destination PC is terminated.

Therefore, according to the second embodiment, if the directory name in which the user program is stored is input,
Referring to the link table, only the program files registered in this link table among the program files stored in that directory are established with the transfer destination PC and the communication path corresponding to the file name, the transfer of the program, Since the program transfer process is performed by repeatedly releasing the communication path, the program corresponding to multiple PCs can be automatically transferred by only one process of inputting the directory name in which the user program is stored. It is not necessary for the person to move between PCs, and the work of switching the transfer destination PC is also unnecessary automatically, and it is possible to perform another work while away from the device even when the device is operating.

In the second embodiment, the file name of the user program in which the user program to be transferred is stored is designated by designating the directory name. However, the present invention is not limited to this. Instead, for example, a directory in which user program files to be transferred are stored is determined in advance, and the user program is transferred as described above by referring to the link table from the directory without specifying the directory name. good.

Further, in the second embodiment, as in the first embodiment, the node number is adopted as the identification number of each PC, and the node number registered in the work memory of each PC is the identification number of each PC. However, the present invention is not limited to this, and an identification number other than the node number of each PC may be adopted as the identification number of each PC, and the identification number of each PC cannot be registered in the work memory. In such a case, the password command of the program registered in the program stored in the memory of each PC may be used as the identification number of each PC.
