Further, the general-purpose process control module corresponding to the registration sequence number 101, for example, the general-purpose preparation control module 55, is read from the storage unit @60 into the storage unit 83a of the control device 83.

In the basic image 80, the main operation refers to the main control operation to be performed in each process control sequence.

The initialization top cover turn among the main operations of the basic image 80 is the initialization control stage 1! which should be performed first in the process sequence control procedure 54! i! Refers to the pattern to be selected in i 54a, in which a predetermined pattern is selected from among the three patterns in Table 1. When preparing raw material A, pattern 1 sets all direct active carriers to non-operating state.
is selected, and after moving the cursor within the frame 87, input 10p1 from the keyboard 82. This input content is written into the storage section 83a of the control device 83 and displayed at a predetermined location 87 on the screen 69a of the display 69.

In the basic image 80, the module refers to the general-purpose process sequence control module 55, 56, 57. For example, when the registration sequence number mentioned above is specified in the frame 86, the name given to the module 55, 56, 57 is the module 5.
5.56 or 57 is read into the storage section 83a of the control device 83 and displayed in the frame 88. In the case of the preparation control module 55 with the registration sequence number 101, for example, preparation 1 is displayed. Note that instead of automatically displaying "Preparation 1" in the frame 88, the name may be input from the keyboard 82.

In the basic image 80, boxes 89.90 are fields in which the general process sequence control module 55, 56, 57 specifies the starting point device and ending point device to be used for a specific process sequence Ill all. Registration sequence number 101
When using the control module 55 for preparing raw material A, the starting point device is the raw material A storage tank ST1 and the ending point device is the reaction tank R1.
Enter ST1 in the box 90 and R1 in the box 90. This input content is written to the storage section 83a of the control device 83 and is also written to a predetermined location 89.90 on the screen 69a of the display 69.
will be displayed. Note that the designation or input of the starting point device and the ending point device may be performed using the light bench using the CAD system as described above.

When a specific module such as the general-purpose preparation module 55 is specified as the registration sequence number 101 as the general-purpose process sequence control module, parameters PR1, PR2, PR3, PR4 related to the general-purpose preparation module 55 are displayed in the frame 91 of the screen G9a of the display 69. are displayed as R1 R2 R3 R4. Then, when ST1 and R1 are specified as the start point device and end point device in the frames 89 and 90, the parameters PRI, PR2°PR3, PR4 are specified in the frame 91.
Among them, the device name P1. corresponds to the device parameter PR1 representing the pump, the device parameter PR2 representing the valve, and the device parameter PR3 representing the flow meter. XV1. FQC1 is generated by the generation device 59 and displayed as follows.

PRI Pi PR2XVl PR3FqCl R4 Correspondence is established for the numerical parameter PR4 by moving the cursor to the right side where PR4 is displayed and inputting, for example, 500 in liters from the keyboard 82.

The contents of the parameter correspondence 4j in the frame 91 completed as described above are displayed in the frame 91 of the screen 69a of the display 69, and are also stored in the storage section 83a of the control device 83, and are further processed by the module program generation device 59 into the module. It is generated as a program 78.

In the basic image 80, the initial conditions (both initial conditions 1 and 2) are the initial conditions to be checked in the check step 54b of the initial conditions 54c before the module program execution step 54d in the process sequence control procedure 54. For example, when charging raw material A, it is necessary to close the outlet valve XV5 of reaction tank R1, to make sure that there is nothing left in reaction tank R1 (liquid level in percent units is O), and to make sure that the raw material If it is required that tank STI in A has a predetermined amount or more of raw material (liquid amount in percent units is greater than 20), then frame 921 corresponding to the initial condition is required.
After moving the cursor to 93, press XV5 from the keyboard.
Key in: Close LT2=0 LT3>20. This input content is displayed at predetermined locations 92 and 93 on the screen 69a of the display 69, and is also stored in the storage section 83a of the control unit 83.

In addition, instead of inputting kanji as ``shusei'', for example, you can input ``heishi'' or ``heishi'' in kana, or even if you input alphanumeric characters as rcLO8EJ, you can input other symbols or codes. It's okay. (Same for other frames).

In the basic image 80, the initial condition 2 refers to a condition for restarting a certain process sequence control procedure 54 when the sequence control procedure 54 is interrupted during its execution for some reason.

For example, in the case of preparing raw material A, initial condition 2 is rXV5
"closed".

In the basic image 80, monitoring refers to monitoring the reaction tank temperature, etc., as necessary during execution of the process control procedure 54.

If the process sequence control is, for example, the preparation of raw material A, no special monitoring is performed, so the monitoring designation column 95 is left blank.

The designation, display and storage of the designated contents in this frame 95 are performed in the same manner as in the case of other frames.

In the basic image 80, the abnormality processing is the main process sequence control 54 by executing the main process sequence control module program among the process control procedures 54 in FIG.
If an abnormality is detected during the execution of d (
54x) refers to the abnormality handling process 54V that is executed unconditionally.

When the main process sequence control is the preparation of raw material A, abnormality monitoring and abnormality processing are not performed, so the abnormality processing specification column 96 is left blank.

The designation, display and storage of the designated contents in this frame 96 are performed in the same manner as in the case of other frames.

As described above, the blank space 84 of the basic image 80,...
. . , 96 is filled in and an image 97 specifying, for example, the preparation process of raw material A is formed, the preparation control module program 78 for raw material A generated by the module program generation device 59 under the control of the control device 83 A preparation sequence control program for raw material A incorporating the above is generated and stored in a peripheral storage device 98 such as a magnetic disk.

In the raw material charging sequence control program, the content i0DI of the initialization cover turn iop may be incorporated as is in the form of an execution program, or may be cited as a subroutine.

In FIG. 13, reference numeral 110 shows an example of specification for generating a process control program in the case of charging catalyst B in process number 2.

In this case, the registration sequence 101, ie, the use of the preparation 1 as a general-purpose module, is the same as in the case of the preparation of the raw material A, but since no pump is used, PR1 is left blank.

In addition, 1op2 is used as the initial output cover turn, and the motor M is operated to cause the raw material A in the reaction tank R1 to be stirred by the stirrer 3.
This differs from the case of charging raw material A in that the catalyst B and the catalyst B being charged are stirred, and in the content of the initial conditions.

In FIG. 14, reference numeral 111 shows an example of specification for generating a process control program in the case of charging raw material C of process number 3.

In this case, the registration sequence 101, that is, the use of the preparation 1 as a general-purpose module, is the same as in the case of material preparation, but since the starting point device and piping system are different, the equipment corresponding to the parameters is different. Of course, the initial conditions are also different.

Also, 1op3 is used as the initial cover pattern,
Raw materials A and C in the presence of catalyst B with the start of charging raw material C
Cooling is performed with the refrigerant by adjusting the opening degree of valve XV4 so that the heat generated by the reaction during the reaction can be removed as necessary.

Furthermore, the reaction tank temperature T is monitored by the temperature detector TE, and if the temperature T is 45°C or higher, the direct active equipment is unconditionally set to the abnormal processing state specified by 1op3, and the charging of the raw material C is interrupted. Ru.

In addition, the initial condition 2 in the case of preparing raw material C is "T≦40"
It is.

In FIG. 15, reference numeral 112 shows an example of specification for generating a process control program for the post-reaction of process number 4.

In this case, as the registration sequence 104, the stationary module 56 with the registered module name stationary is used.

In the stationary module 56, the start point device and the end point device are unconditionally reaction columns, so even if columns 89 and 90 are left blank as shown in the figure, taking into consideration the case where there are multiple reaction vessels in general-purpose equipment, etc. R1 may be specified in either or both of columns 89 and 90.

In the case of the stationary module 56, only the numerical parameter PR1 is required to be specified, so, for example, 60 in minutes (ie, 60 minutes post-reaction) is input in the box 91.

In the case of the post-reaction, the initial output pattern, monitoring conditions, and abnormal treatment are the same as in the case of charging raw material C.

In FIG. 16, reference numeral 113 shows an example of specification for generating a process control program in the case of process number 5, which is static.

In this case, the point that "Stand" is used as the registration sequence 104, that is, the general-purpose module, is the same as in the case of the post-reaction.

Note that this differs from the post-reaction in that stirring is not performed (iopl) in order to separate the product 2 and waste liquid 34 based on the difference in specific gravity.

In FIG. 17, reference numeral 114 shows an example of specification for generating a process control program in the case of waste liquid separation of process number 6.

In this case, the transport module 57 with the module name "transfer" registered as the registration sequence 106 is used,
In order to transfer the waste liquid 34 from the reaction tank R1 to the tank D, the related start point device R1 and end point device DT are specified, the related device name is automatically generated and specified as the device parameter, and the related numerical parameter is specified. ing.

In the case of waste liquid separation, the initial cover turn is the same as in the case of standing still.

(in percent).

In FIG. 18, reference numeral 115 shows an example of specification for generating a process control program in the case of product transfer of process number 7.

In this case, the registration sequence 106, that is, the use of "transfer" as a general-purpose module, the initial export pattern,
Although the monitoring conditions and the presence or absence of abnormal treatment are the same as in the case of waste liquid separation, the end point equipment and part of the piping system are different, so the equipment corresponding to the parameters is different.Of course, the initial conditions are also different.
