Note that the same reference numerals indicate the same objects throughout the figures.

Hereinafter, the setting data checking method of the present invention will be explained with reference to FIG.

In this embodiment, for convenience of explanation, one monitoring device 4 is used.
As an example of an adapter, a communication control processing unit (CCP)
An example of N line interface units (LICs) (adapters 1 to n) is shown. In addition, there are two setting registers (150, 151) in one adapter 15. For example, the line address is set in the setting register (11, 21, 3L-・Nl) 150. , configuration register (
12, 22, 32, -.N2) 151 is defined to set the communication speed.

First, the monitoring device 4 prepares setting data 5TDATA for the adapter 1 (15) in the setting data creation circuit 44, and sets the data in the setting register 150.
Data 5ELREG for selecting 151 is created by the setting register selection data creation circuit 45.

Here, from the timing generation circuit 46, the setting register 1

By issuing K, the above setting data ST[)AT
Setting register 150.A selected. or set to 151.

Similarly, setting data is set up to adapter N (15).

The setting data is stored in the setting register 150. Or, in order to check whether the setting registers 150 . Alternatively, selection data is set via the 5TDATA line so that the output of 151 is selected.

Here, a signal CHK ? indicating the mode for checking the setting data is sent. By energizing IOD to “on”,
The setting register 150. selected by the value set in the selection register (1 to N) 152. Or, a specific operation is executed in the arithmetic circuit 154 using the output of 151 and the external input data CKDATA t for the adapter 1 (15), and the external input data of the next adapter 2 (15) is used as the operation result data CKDATA1. It works as follows.

Since the setting data created in advance is known in the monitoring device 4, the expected value creation circuit 47 performs a cyclic code (CRC) operation similar to that described above based on the data to generate an expected value.

Then, by comparing the value of CKDATA N with the expected value generated in the monitoring device 4 in the comparison circuit 41, if the result is a failure, it is determined that the setting was performed correctly. If there is a mismatch, it is recognized that the setting of one of the adapters is incorrect and a correction process is started.

In this way, when specific data is set from a monitoring device to a plurality of adapters, the present invention allows specific data to be set between the set data and the external input data for each adapter in each adapter. The calculation results are used as external inputs to the next adapter, and the calculation results of all adapters are sent to the monitoring device.
The feature is that the setting data is checked by comparing it with the expected value created in advance.

In the above embodiment, a plurality of adapters (1 to N
) 15 in the configuration register 150. 151 and external input data for the adapter, cyclic code (CRC) calculation has been explained as an example, but considering the purpose of the present invention, it is not limited to this. Needless to say, this is true.

〔Effect of the invention〕

As explained above in detail, the configuration data check method of the present invention allows the monitoring device to check multiple adapters.
In an information processing device that configures data, each adapter has a configuration register that configures specific data, and a specific Means for providing an arithmetic circuit that performs an arithmetic operation, for example, a cyclic code (CRC) arithmetic operation, and a mechanism for using the arithmetic result as the above-mentioned external input data of another adapter, and notifying the above-mentioned monitoring device of the arithmetic result from the final stage adapter. By providing the above, the result output calculated by each adapter is compared with the expected value by the monitoring device, and the normality of the specific setting data for each adapter is checked. There is no need to read out the setting data set in the setting, and it can be determined whether the setting values are correct or not with a single check, which reduces the checking time and reduces the total setting time from the start of the setting operation to the end of the check. be.
