FIG. 5 is a flowchart showing the processing of the network configurator 400 shown in FIG.

Referring to FIG. 5, first, in this network configurator 400, each slave unit 20
Setting switches 201-1 to 201 of 0-1 to 200-n
It is checked whether a check instruction of -n has been input (step 501).

Each of the slave units 200-1 to 200-20
The check instruction of the 0-n setting switches 201-1 to 201-n can be input by, for example, clicking a setting switch check button displayed on the display screen of the network configurator 400 with a mouse or the like.

When it is determined in step 501 that the check instruction of the setting switches 201-1 to 201-n has not been input (NO in step 501), the process returns to step 501 and waits for the input of this check instruction. Is determined that a check instruction has been input (step 50).
1 and YES), and then the slave units 200-1 and 200-2
The unit number n of 00-n is set to “0” (step 502), and it is checked whether the unit number n is the last (step 503).

If the unit number n is not the last (NO in step 503), first, a command is issued to read the setting state of the setting switch of the slave unit having the unit number n (step 504).

Then, according to this command, the unit number n
Then, the setting state of the setting switch read from the slave unit is compared with the set value of the design setting switch registered in advance corresponding to the setting state (step 505). This comparison is performed by the comparison unit 405 shown in FIG.

The result of this comparison is stored in a storage unit (not shown) (step 506), and the unit number n is incremented to n + 1 (step 507).
It returns to step 503.

By repeating the above processing, when it is determined in step 503 that the unit number n is the last (YES in step 503), each of the slave units 200-1 to 200-n is determined based on the stored comparison result. Of the setting switches 201-1 to 201-n of the setting switches 201-1 to 201-n registered in advance or not are displayed (step S1). 508), this process ends.

The comparison result is displayed on the setting switch 201 of each of the slave units 200-1 to 200-n.
Whether or not the setting state of -1 to 201-n matches the design setting value of each of the setting switches 201-1 to 201-n registered in advance, and if not, depending on the inconsistent contents etc. Is displayed.

In the above embodiment, the setting switches are read and compared by the slave units 200-1 to 200-.
Although the description has been given of the case where the operation is performed collectively up to n, the operator of the network configurator 400 may individually input and designate the unit number n of the slave unit to be processed to read or compare the setting switch of the specific slave unit. Good.

In the above embodiment, all the slave units 200-1 to 200-n have been described as including the setting switch reading means. However, the configuration of the network unit includes the setting switch reading means. It is also conceivable to have a configuration in which a slave unit that performs reading and a conventional slave unit that does not have a setting switch reading unit coexist.

However, a conventional slave unit having no setting switch reading means responds to an error in response to a command to read the setting state of the setting switch from the network configurator 400. It can be determined that the slave unit is a conventional slave unit that does not include a setting switch reading unit.

The network configurator 40
0 indicates that the model of the slave unit connected via the network can be determined, so that it is possible to issue a command to read the setting state of the setting switch only to the slave unit having the setting switch reading means.

Therefore, the present invention can be easily applied to a network in which a slave unit having a setting switch reading means and a conventional slave unit having no setting switch reading means are mixed. it can.

[0061]

As described above in detail, according to the present invention, when the system is started, the setting state of the setting switch of each network unit connected to the network is taken up by the network configurator. Since the setting status of the setting switch of each network unit is displayed or compared with the design value of each setting registered in advance, the comparison result is displayed. The setting state of the setting switch of the unit can be checked easily and in a short time, whereby the time required for starting up the system can be greatly reduced.
