2. Description of the Related Art Conventionally, a molding machine is controlled by a controller equipped with a microcomputer system. The controller processes the data sent from the molding machine and sends the control data for controlling the molding machine to the molding machine. Data exchange between the molding machine and the controller is performed via the I / O port. On the controller side, data processing is performed using the number (physical line number) assigned to the signal line (physical line) connected to the I / O port as it is as the line identification.

However, the controller of the conventional molding machine described above has the following problems. For example, connection of signal lines may be changed or signal lines may be added to change the control mode of the molding machine. In that case, the conventional physical line number cannot be used as the line identification. Therefore, it is necessary to change the controller program, but the program cannot be changed immediately. Therefore, there is a problem in that the operation of the molding machine must be stopped for the time required to change the program. Further, even if a physical line number that is no longer used due to a change in the connection of a signal line occurs, the vacant physical line number cannot be assigned to a newly connected signal line unless the program is changed. Therefore, it may be necessary to newly add an I / O board. Therefore, it is an object of the present invention to provide a controller of a molding machine capable of easily changing the line identification even when the physical line is changed.

Reference numeral 20 denotes a microprocessor (M
PU). The MPU 20 stores the physical line number and the logical line number input via the input unit 14 in the storage unit described later in association with each other, and combines the physical line number and the logical line number stored in the storage unit. Based on the above, the data sent from the signal line 13 is input to the logical line 15 to which the logical line number corresponding to the physical line number of the signal line 13 is given. Further, the MPU 20, based on the combination of the physical line number and the logical line number stored in the storage means, sets the data sent from the logical line 15 to the physical line number corresponding to the logical line number of the logical line 15. Signal line 1 attached
Enter 3. Further, when the physical line number and the logical line number corresponding to the display 16 are still displayed, when the change of the physical line number and the logical line number is inputted through the input means 14, the contents of the storage means are updated. At the same time, the exchange of data is controlled by the combination of the updated physical line number and logical line number. In addition, the MPU 20 identifies the I / O board connected to the I / O port 18, and controls each part of the injection molding machine including the injection molding machine 12 including the controller 10 of this embodiment.

Reference numeral 22 denotes a storage means, which is composed of, for example, a RAM and an external memory, and stores a physical line number of the signal line 13 for exchanging data and a logical line number of the logical line 15 in association with each other. In addition, MPU20 in RAM
The data input to the I / O board, the identification of the I / O board identified by the MPU 20, the information processed by the MPU 20, the calculation result, and the like are temporarily stored.

Next, an example of changing the wire number will be described. Here, the change of the wire number (input wire number) of the input system for sending data from the injection molding machine 12 to the MPU 20 will be described. When the input means 14 is operated to instruct to start changing the input wire number, the MPU 20 reads the control program, clears the RAM of the storage means 22, reads the table of the wire number currently set from the external memory, and stores it in the RAM. It is written and displayed on the display 16. An example of this display 16 screen is shown in FIG.

In FIG. 2, the input wire number table 26 is shown in the center frame. In each frame, "logical wire number-physical wire number" is shown. For example, the logical line 15 having the logical line number "0" receives data from the signal line having the physical line number "10". T1 is a touch area for designating the change of the logical wire number. By operating the touch contact of the corresponding touch panel, the input is designated and the logical wire number to be changed is inputted from the keyboard. .. T2 is a touch area for designating the change of the physical wire number. By operating the touch contact of the corresponding touch panel, the input is designated and the physical wire number to be changed is input from the keyboard. .. T3 is a touch area for designating cancellation of input,
It is designed to be canceled by operating the touch contact of the corresponding touch panel.

T4 is a touch area for inputting an instruction to change the screen into an output wire number (wire number of the output system for sending data from the MPU 20 to the injection molding machine 12) table.
The display is changed by operating the touch contacts of the corresponding touch panel. When the screen is the output wire number table, "input wire number table" is displayed in the touch area T4. T5 is a touch area for designating the I / O board. By operating the touch contact of the corresponding touch panel, the input is designated, and the I / O board for which the table 26 is to be displayed is identified from the keyboard (this implementation). In the example, the identification number) is input.

When the operator operates the keyboard and the touch panel of the input means 14 to change and input the logical wire number and / or the physical wire number in the state where the above screen is displayed, the MPU 20 stores the changed contents. The contents of the means 22 are rewritten. As a result, the MPU 20 controls the data transfer according to the changed logical wire number and / or physical wire number. The operation procedure for the output wire number table is also the same, so description thereof will be omitted. When the wire number can be changed in this way, even if the connection of the signal line 13 is changed, it is only necessary to input the change of the target wire number according to the procedure described above, which is called a conventional program change. No need for troublesome work. In addition, when a wire number becomes vacant, a new signal line 13 can be assigned to the vacant wire number by changing the wire number, so that efficient wire number allocation can be performed, and I / O can be unnecessarily increased. There is no need to add an O board. If necessary, the physical line may be identified by a character, a code or the like instead of the physical line number. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, as a logical line identification, characters and symbols are used in addition to logical line numbers. Of course, many modifications can be made without departing from the spirit of the invention.

[0014]

When the controller of the molding machine according to the present invention is used, in the first configuration and the second configuration, the physical line number and the logical line identification are displayed on the display in correspondence with each other. Further, since the control means stores the physical line number and the logical line identification inputted through the input means in the storage means in association with each other, the operator changes the combination of the physical line number and the logical line identification while looking at the display. Since it becomes possible, it is not necessary to change the program even if there is a change in the connection of the physical line, and the process of changing the connection can be completed in a short time. Further, even if a vacant line number is generated, the vacant line number can be used by changing the line number, so that the line can be used efficiently, and so on.
