[0005]

SUMMARY OF THE INVENTION Among the above conventional examples,
In the case of the first conventional example: a) In the case of multi-product production G required depending on the manufacturing method
Since the D texts are different, the number of GD texts that can be registered in the system may be insufficient. That is, when GD texts for all varieties are registered in advance, the GD
The number of words decreases. Also, when the same apparatus, for example, the same reaction apparatus or drying apparatus is present during the production process of different varieties, a different GD is used even with the same GD wording.
Must be registered as wording. This is another GD wording to identify which device caused a factor such as failure when the same product is produced in parallel by different production lines, even if it is not a production process of different types. You need to register.

B) Since the software of the PCS program and the GD text processing are separately designed, engineering such as arrangement of delivery marks is required.

C) The correspondence between the GD text and the device is obvious,
D wording and the running product production unit (hereinafter called batch)
The relationship with is not obvious. For this reason, when it is necessary to keep a history of GD texts generated in batch units, considerable engineering is required.

D) The GD text is displayed as a result of the factor event, and it is not possible to display in advance the GD text relating to the event to be executed in the future.

In the case of the second conventional example, since the GD word is included in the recipe for each product type and the GD word is selected and the type is produced, the GD word is insufficient even in the case of multi-type production. It does not occur. Further, since the GD text is registered as a part of the PFC program, the engineering as in the above b) does not occur. Unexecuted P
By adding the function of selecting the FC step and displaying the content, the GD text relating to the event to be executed in the future can be displayed in advance.

However, in this conventional example, a) recipes having the same or similar manufacturing procedures except that parameters indicating manufacturing conditions are different, and even if the contents of the GD text are the same, the recipe must be registered for each recipe. .

B) A GD wording for a rough manufacturing procedure, and a detailed GD wording when executed by the PCS, for example, a GD wording when an abnormality occurs during execution of one process is issued. I can't do that.

C) The relationship between the GD word and the batch is obvious,
The relationship with the manufacturing equipment is not obvious. Therefore, when there are a plurality of the same or similar manufacturing apparatuses, the responsiveness when performing a specific operation in response to the GD wording deteriorates.

D) As part of the PFC program,
The GD text is only a character string due to capacity restrictions and the like, and further restrictions such as the number of characters are generated.

[0014] It is therefore an object of the present invention to provide a system that provides operators with appropriate and rich GD language in the case of multi-product production.

As described above, in the operation guide display device for the multi-product production process of the present invention, the GD text is basically associated with the steps of the PFC as in the second prior art. However, the apparatus according to the present invention is different from the prior art in that: 1) The PFC registers not the GD text itself but tag information such as a document file name for citing the GD text. These GD texts are stored in an area that can be commonly referred to from each batch in the GD text file. 2) The PFC (the whole or lower hierarchy in the case of a hierarchical structure) including the GD indicator information corresponds to the execution device. , And the process control system PCS1, PCS2,..., Which is downloaded to the unit TAGn in the PCSN and executed.

The present invention is not limited to the above embodiment, and various modifications are possible.

That is, in the above embodiment, G
The D text file 3 is provided in the HMI, but may be installed in another station on the network.

The registration of the GD text to the PFC can be performed by registering the entire file name of the GD text for each PFC in the recipe, or by registering one GD text file for one recipe. , Each P in the recipe
In the FC, a system that registers a part (extension or the like) of the GD text file or a display position (text address) in the GD text file or the like is also possible.

In this case, the present invention can be applied to a model in which the PCS cannot handle character information.

Furthermore, in the above-described embodiment, the PFC included in the recipe of the corresponding product type is downloaded to the PCS every batch production or at the time of product type switching. The PFC may be DL in the PCS at the time of raising.

That is, this method is as follows: 1) A GD text file name corresponding to an arbitrary step of the PFC is registered, and the PC is executed before the PFC is executed.

According to this method, the number of PFCs is limited to the PCS capacity as compared with the above embodiment, so that there is a restriction that the manufacturing procedure is limited to the selection and rearrangement of the execution procedure within the range. On the other hand, since the DL of the PFC is not required at the time of batch production, the reliability can be improved such that the HMI for managing the recipe can be produced even in the event of an abnormality.

Further, in the above embodiment, the PCS has a DL
Is a GD alerting method based on the specified PFC, but the PF of the upper layer executed by the HMI in the layered PFC
C may be used to issue a GD.

That is, in this method, 1) a GD text file name corresponding to an arbitrary step of the PFC in the recipe is registered.

2) A recipe corresponding to a kind to be manufactured is designated for each batch. At the time of batch production execution, the recipe is transferred to the batch TAG and the production of the product is executed. (Actually, the PMI of the PCS corresponding to the PFC lower layer from the HMI
By starting the FC process, the process is controlled. 3) According to the PFC execution progress in the HMI, the batch TA
The GD document file name in G is updated to the content of 1).

The following is step 3) in the above embodiment.
5).

This method is applied to a model that can execute PFC on the HMI.

Further, in the system of the above-described embodiment, the PFC is operated in the unit TAG by DL. However, this can be used together with the system of operating the PFC by the batch TAG.

That is, in this method: 1) A GD text file name corresponding to an arbitrary step of the PFC in the recipe is registered.

2) A recipe corresponding to the type to be manufactured is specified for each batch. At the time of batch production execution, the recipe is transferred to the batch TAG and the production of the product is executed. HM

According to the present invention, the following effects can be obtained.

A) Since the designation of the GD document file can be changed for each recipe, the number of GDs that can be managed can be increased.

B) Since GD information is directly set on the PFC, engineering is easy.

C) Since the recipe is downloaded to the PCS as information on the patch being manufactured, the relationship between the GD and the batch becomes obvious.

D) By adding a function of selecting an unexecuted PFC step and displaying the contents, a GD relating to an event scheduled to be executed in the future can be displayed in advance.

E) If the GD document file name is the same between arbitrary recipes, GD text can be shared.

F) The GD text itself can be a separate file.
Therefore, it is possible to perform GD in any form (combination of charts and photographs, long culture, audio information, etc.).

H) Since the GD can be specified for the PFC executed in the PCS, it is possible to issue a fine GD alert.

G) Unit TA corresponding to the device to be executed
Since it is DL to G, the correspondence between GD and the device becomes obvious.
In addition, since the GD is in the form of a GD for the device, the GD text itself does not need a device name, and it is easy to share the GD text.
