[0002]

2. Description of the Related Art In a monitoring system for a large-scale plant, input / output data such as process data of a plant is input, predetermined processing is performed, and thereafter, calculation processing is performed by various processing programs. In such a process, input / output data is processed for each input / output point using input / output point numbers defined in advance by an input / output point list.

[0003] However, input / output data is frequently changed at the production stage or at the time of plant equipment remodeling.
The work of changing the input / output point list requires a great deal of labor.

Further, in order to carry out a confirmation test of the above-mentioned changed portion of the input / output point list, every time a change occurs, it is necessary to find out and use the input / output point number required for carrying out the confirmation test from the input / output data list. In addition, there is a problem that a great deal of labor is required, and a confirmation test failure due to an input / output point number error or leakage is apt to occur.

Further, when the confirmation test is performed, the correspondence between the input / output point list and the items on which the confirmation test has been performed is not known.

In order to solve the above problems, Japanese Patent Laid-Open No.
There is an instrumentation data management device disclosed in JP-A-314275. This device prepares an input / output point list for the entire plant to which a tag number (input / output point number) for identifying input / output data is assigned, and reads the signal content of each input / output data in the input / output point list. Analog input,
A list for each module such as an analog output, a digital input, and a digital output is automatically generated.

However, in this case, since the input / output point list handled by the entire plant is not automatically created, it takes effort to create the list, and a tag number (input / output point number) must be assigned to each input / output data.

There has been a problem that a great deal of labor is required and that a confirmation test failure due to an input / output point number error or leakage is likely to occur.

Furthermore, when the confirmation test is performed, the correspondence between the input / output point list and the items on which the confirmation test has been performed is not known, so that there is a problem that the confirmation test is likely to be defective due to omission of the confirmation test items.
