The monitor items that are taken in include time monitoring items, position monitoring items, rotation speed monitoring items, speed monitoring items, pressure monitoring items, temperature monitoring items, power monitoring items, and other important items of the molding operation condition setting items described above. Are almost overlapping.

The display control unit 23 uses the key input device 4 to call a display image in a mode desired by the operator, and based on a display image creation / control program created in advance, the data conversion processing unit 24 and the display unit. By controlling the fixed data storage unit 25, the image data generation / storage unit 26, etc., the data of the entire display mode image designated in the image data generation / storage unit 26 is created / stored. That is, the display control unit 23 causes the data conversion processing unit 24 to extract the data used for displaying the display mode image from the information stored in the molding condition setting storage unit 20 and the measured value storage unit 22 as needed. At the same time, the key input data processing unit 28 receives the input data of numerical values and symbols and the cursor position information, which are primarily stored in the key input data processing unit 28, converts them into image data, and sends them to the image data generation / storage unit 26. In addition, the display control unit 23 uses the fixed data for a large number of mode images, which are created and stored in advance in the display fixed data storage unit 25, such as characters, symbols, graphic figures, and ruled line data, to display the display mode image. Data to be used for display is extracted and sent to the image data generation / storage unit 26. Image data generation / storage unit 2
In 6, based on the image composition program created in advance,

And keep it rewritable.

The image data of the image data generating / storing section 26 is transferred to the frame buffer 27 by the display control section 23 and temporarily stored therein, and the output of the frame buffer 27 is displayed by the instruction of the display control section 23. The image data in the predetermined mode is sent to the device 6 and displayed on the display screen of the display device. And
Now, depending on the operator, 1 of the setting condition display mode image
When one is selected, the image data of this setting condition display mode is generated and displayed on the display screen of the display device 5, whereby the microcomputer 1 automatically or by a predetermined key operation after that, the microcomputer 1 operates under operating conditions. The mode for setting (or rewriting) a value is accepted. Therefore, in this state, the operator uses the cursor movement key group 10 to move the cursor to the condition setting field of the item to be set, and thereafter, the numeric key group 11 is used to input the set numerical value and display it in the condition setting field. Then, by confirming the displayed numerical value and then performing a registration operation using the entry key 14, the microcomputer 1 can operate the internal setting condition storage unit 20.
By registering / storing the set numerical value in the area corresponding to the setting item and repeating this procedure, the setting of each operating condition is sequentially performed.

That is, when a registration operation is performed using the entry key 14, the numerical data temporarily stored in the key input data processing unit 28 is transferred to the input set value determination processing unit 29, and the input set value determination process is performed. The unit 29 determines whether or not the input numerical data is within the permissible range determined in advance by a case study for each setting item (compared with the content of the permissible range setting table (not shown)), When it is within the allowable range, the input numerical value data is automatically aligned in the input set value determination processing unit 29 to the number of significant digits defined for each setting item and transferred to the setting condition storage unit 20. It has become so. On the other hand, when the input numerical data is outside the permissible range determined in advance by the case study for each setting item, the input set value determination processing unit 29 stops the transfer of the numerical data to the setting condition storage unit 20. Then, an alarm is generated by a warning sound generating means (not shown). By doing so, the situation in which erroneous data is set is suppressed as much as possible, and the effective digit number is automatically adjusted, which is highly convenient for the operator.

Here, the display control unit 23 recognizes that the image data currently displayed is the setting condition display mode image, and the cursor from the key input data processing unit 28 is recognized. The current cursor position is also recognized by the position information. In the present embodiment, the calculator function image 16 can be called in any display image mode, and calculation using the calculator function can be performed in any screen mode. The calculation result using the image 16 can be automatically registered and set only when the current display mode is the setting condition display mode image and the current cursor position is in the condition setting field of the optional setting item on the screen. Limited. Therefore, in order to calculate and register the set numerical value by the built-in calculator function of the microcomputer 1, the operator moves the cursor 15 to the condition setting field of the setting item by operating the cursor moving key group 10, "Calculator" selection key 9
Push -2. As a result, the calculator function display data is read from the display fixed data storage unit 25 based on the command from the display control unit 23, and is combined with the setting condition display mode image in the image data generation / storage unit 26. The contents of the frame buffer 27 are rewritten and updated, and the display screen of the display device 6 displays the current cursor 1 along with the setting condition display mode image as shown in FIG.
The calculator function image 16 is displayed in a window at a screen position other than the position 5.

In this state, as described above, the corresponding key group on the key input device 4 displayed in the calculator operation key function display section 17 in the calculator function image 16 is used for inputting the displayed characters and symbols. The cursor 1 functions as a key group, and after the calculation result calculated using the key group displayed on the calculator operation key function display unit 17 is confirmed on the calculator calculation display unit 18, the entry key 14 is pushed to move the cursor 1 described above.
The numerical value obtained by the calculator function is displayed in the condition setting column of the setting item where 5 is located, and the setting numerical value is stored in the area corresponding to the setting item of the setting condition storage unit 20 in the microcomputer 1. Of course, also in this case, the input set value determination unit 29 determines whether or not the input numerical data is within the permissible range determined in advance by a case study for each setting item, and is within the permissible range. In this case, the input numerical data is automatically aligned by the input set value determination processing unit 29 to the number of significant digits defined for each setting item and transferred to the setting condition storage unit 20. There is.
If the input numerical data is outside the permissible range set in advance by a case study for each setting item,
The input set value determination processing unit 29 stops the transfer of the numerical data to the setting condition storage unit 20 and causes an alarm (not shown) to generate an alarm. By doing so, the input setting of the numerical data of the operating condition setting items that must be calculated based on the predetermined calculation formula becomes easy and reliable, and the usability is improved.
