Abstract

PURPOSE:To produce the accurate data in a short time by supplying the initial information, an input terminal parameter, and a logic flow to an optional ROM via an input device. CONSTITUTION:An input/output setting part 2 sets an input/output terminal parameter of an ROM 11 at an input/output terminal parameter data bank 4 based on the input of an input device 1. A logic flow setting part 3 sets a logic flow at a logic flow data bank 5. A data production part 6 reads the input/output terminal parameter and the logic flow out of the banks 4 and 5 respectively and sets the logic flow to all valid addresses of the optional ROM 11 to be produced. Thus, the part 6 produces the ROM data and stores this data into a data bank 7. An ROM writing part 8 transfers the data on the bank 7 to an ROM writer 9 and sends a writing instruction to the optional ROM 11. In such a way, the accurate data can be produced in a short time without manual operation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an improvement in a ROM data creation system, and in particular to a ROM data creation system in a programmable sequential machine.
Concerning systems that create data.

(Prior art) Conventionally, in this type of ROM data creation system,
After creating a logic flow related to programmable ROM data, manually create a logic flow for all valid addresses of the ROM, create data, and then input the created data into a ROM writer to create a sequential ROM. (Problem to be determined by the invention) The conventional sequential ROM data creation system described above has problems in creating a logical flow, creating ROM data, and
Creating a sequential ROM after setting data in the OM writer is done individually. For this reason, nine manual intervention is required to transfer the data. Friend, in the above configuration, there is a risk that the data will be incorrect.Furthermore, it is necessary to manually create data that corresponds to the logical flow, which takes a long time, and there is also a risk of creating incorrect next data. There is a drawback to being large.

An object of the present invention is to eliminate the above drawbacks by inputting initial information, input/output terminal parameters, and logic flow to any ROM from an input device, and to create accurate data in a short time. The object of the present invention is to provide a ROM data creation system for a sequential machine.

(A precautionary measure to solve the problem) The ROM data creation system for a sequential machine according to the present invention includes an input/output setting section, a logic flow general section, a data creation section, and a ROM writing section. It is something.

The input/output setting section is an arbitrary ROM input from an input device.
This is for setting the input/output terminal parameters of.

The logical flow setting section is for setting an arbitrary logical flow input from an input device.

The data creation section is based on the information set by the input/output setting section and the logical flow setting section.

After executing the logic flow for the ROM address, it is for creating data for all valid address values of the ROM.

The ROM writing section is for causing the ROM writer to write the data created by the data creation section into the ROM.

(Example), - Next, one embodiment of the present invention will be explained with reference to the drawings.

Figure 1 shows a ROM of a sequential machine according to the present invention.
FIG. 1 is a block diagram showing an example of a data creation system.

In FIG. 1, 1 is an input device, 2 is an input/output setting section, 3 is a logic flow setting section, 4 is a data bank for input/output terminal parameters, 5 is a data bank for logic flows, 6 is a data creation section, and 7 is a data bank of 80M data, 8 is R
OM writing section.

9 is a ROM writer, 10 is an information processing device f, and 11 is a ROM
It is.

The input/output setting section 2 is based on the input from the input device.
ROMII input/output terminal parameters in data bank 4
, and the logical flow setting unit 3 sets the logical flow in the data bank 5.

The data creation unit 6 reads input/output terminal parameters and logic flows from the data bank 4.5, associates the logic flows with all valid addresses of any ROMII to be created, and creates ROM data. and stored in the data bank 7.

The ROM writing unit 8 writes the data in the data bank 7 to the ROM.
The data is transferred to the writer 9 and a write instruction is sent to any ROM 11.

In the above, the input/output setting section 2 and the logical flow setting section 3
, data bank 4.5.7, data creation section 6, and R
An information processing device 10 is configured by the OM writing section 8.

(Effects of the Invention) As explained above, the present invention allows arbitrary 'F' to be input from the input device.
By inputting initial information, input/output terminal parameters, and logic flow to LOM, ROM data can be created based on the setting information in the data creation section on the information processing device, and ROM writing Writing is executed to the ROM on the ROM writer in the sequential RO
Since M is created, there is an effect that a sequential ROM holding accurate data can be created in a short time without any human intervention in data creation.
