Since the data processing of I / O information, which is the source of the O allocation table, is enormous, it is difficult to grasp the whole, and information necessary for classification is leaked, and transcription work requires a lot of time because it is manual. Not only this, double transcription or omission of transcription may occur at the time of transcription, which may reduce the reliability of the PLC-I / O allocation table. Also, if there are many device types, the I / O information is distributed in a list for each of a plurality of devices, and even when data is transferred to the PLC-I / O allocation table, a unique logic is required for each list. Therefore, it was difficult to unify the data by computer processing, and it was necessary to rely on human thinking. The purpose of the present invention is enormous,
It is to provide a data processing device capable of performing PLC-I / O allocation work in a short period of time by collectively processing various types of data.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a conceptual diagram of a data processing device of the present invention. The device specification data describes the device name and the like. The PLC-I / O allocation table generation pattern is a matrix in which the control method (shown as control) is plotted on the vertical axis, the operation name, and the input / output device specifications (respectively shown as operation, IO) are plotted on the horizontal axis. A flag (hereinafter referred to as a transfer flag) describes whether or not the operation is necessary as I / O data for each control method. Here, the PLC-I / O allocation table generation pattern is patterned to some extent according to the type of device specification data, and it is not necessary to newly create it in each process. The I / O data table generation means 1 extracts and transfers the device name, operation name, etc. from the device specification data and the PLC-I / O allocation table generation pattern,
An / O data table is created. FIG. 2 is a diagram showing a data table generation flow in the I / O data table generation means. First, from the device specification data, the device name,
The control method is sampled and transferred to the device name column (vertical axis) of the I / O data table (step 21). Next PLC-
The operation name and the input / output device specifications are extracted from the I / O allocation table generation pattern and transferred to the operation name column (horizontal axis) of the I / O data table (step 22). The PLC-I / O allocation table generation pattern is searched for from the control system of the device specification data, and the pattern (transposition flag) in which the control system is coincident is transferred to the I / O data table (step 23). FIG. 3 is a diagram showing the expansion flow of the I / O data expansion means. The I / O data expansion means extracts and transfers the device name and operation name at the transfer flag position and the input / output device specifications to generate a PLC-I / O database. First, the transfer flag of the matrix pattern portion of the I / O data table is determined, and the next step is performed only when the transfer flag is set (step 31).
The device name is transferred from the O data table to the device name column of the I / O database (step 32), the operation name and the input / output device specification are extracted, and the operation name of the I / O database,
Transfer to the I / O card format and I / O type fields (step 33). Step 34 is to confirm the completion of the transfer flag search of the I / O data table. As for the lists of other models such as the sensor list and the valve list, the I / O data table is created for each type of device in the same way as the motor list, and these I / O data tables are put together to create the I / O list.
It is input to the data expansion means. The PLC-I / O allocation table creating means 3 collects the I's collected in the I / O database.
/ O information such as device name, operation name, I / O device specifications
PLC-I / O that sorts and sorts from all angles
PLC-I / O allocation processing, such as determining the address of, is output, the PLC-I / O allocation table is output, and the input / output comment is output. FIG. 4 is a diagram showing a processing flow of the PLC-I / O allocation table creating means. In the case of plant equipment, PLC-I / O assignment is performed by first naming the equipment or operating the equipment (equipment),
The data is sorted and sorted using the I / O type and the I / O card format as keys (step 41). The priority order of the keys varies depending on the plant equipment conditions, software configuration in software design, and the like. After the rearrangement is completed, the head number of the address is designated and the addresses are sequentially allocated (step 42). At this time, different allocation is performed depending on the type of I / O. For example, if it is a digital signal, it is serially added by 1 (bit). If it is an analog signal, it will be a serial number of 16 (bit) each. next,
Conversion to the format of the PLC-I / O allocation table (step 43) completes the PLC-I / O allocation table. further,
The PLC-I / O database is used as a comment in the PLC software by connecting data such as device name and operation name to the PLC software design process (step 44).

[0007]

As described above, according to the present invention,
With the I / O data table created for each device type,
Since the data can be grasped for each type of device and can be viewed in the matrix, the classification and rearrangement work in the PLC-I / O allocation table can be easily performed. Further, the expansion logic from the device specification data to the I / O database differs depending on the device type, but by providing an I / O data table in the middle, it is possible to easily create a wide variety of device specification data expansion logic. can do. It was difficult to grasp the whole because the device specifications were huge P
In the LC-I / O allocation work, I / O data of different equipment types can be finally aggregated as a single I / O database for each facility of the plant. Therefore, grasp the entire I / O data. Also became easier. PLC-I such as classification and rearrangement of each I / O information using the control method, input / output device specifications, etc. in the I / O database as keywords.
Since I / O allocation work can be done in a batch of I / O databases,
It is possible to significantly reduce the working time while helping the thinking of the worker. Improves data accuracy by automating the I / O allocation work that was performed manually, that is, eliminates human error that may occur during transfer work such as double transfer and omission of transfer. This has the effect of significantly reducing the time.
