JPH09288502A - Information sharing method between a plurality of controllers and electronic parts mounting device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the need of changing software in the other controller even if an address in which software in one controller recognizes is changed by using a transfer medium for transferring a table where the name of shared information and the address of information are made into a pair between the controllers. SOLUTION: An operation controller 1 has the symbol table 4 where the name (symbol) of shared information and the address from/into which information is read/written are made into a pair. An operation controller 2 has a function for receiving the symbol table 4. The operation controller 1 writes the symbol table 4 into a data transfer area 5 provided in two port RAM 3 at the time of starting and issues interruption to the operation controller 2. The operation controller 2 receiving the interruption reads the symbol table 4 written into the data transfer area 5. Thus, the symbol table 4 is transferred from the operation controller 1 to the operation controller 2.

/ Run the program in RAM15, and communicate I / F16
And a CPU 14 for controlling the external I / F 13.

An information sharing method between a plurality of control devices of the electronic component mounting apparatus 6 configured as described above will be described below with reference to FIG. 5 as an example of its operation. First, the keyboard 11 is used to input the coordinates of the component to be mounted as an operation instruction command. The input operation instruction command is transmitted to the CPU 14 of the operation control device 2 through the external I / F 13 in the operation control device 2 and the address 0006 of the 2-port RAM 3 in which the operation instruction command previously stored in the ROM / RAM 15 is written. Is acquired, the operation command is written to the address 0006 through the communication I / F 16, and an interrupt is issued to the operation control device 1.

In response to the interrupt, the operation control device 1 refers to the address 0006, in which the operation instruction command stored in the ROM / RAM 15 in the operation control device 1 is written, through the communication I / F 16 to give the operation instruction. A command is sent through the external I / F 13 to the head unit 7, component supply unit 8, XY
Notify table 9. In response to the contents, the head section 7,
The component supply unit 8 and the XY table 9 operate, and the head unit 7 sucks the electronic component from the component supply unit 8 and mounts the electronic component on the positioned XY table 9.

Further, the position information of each part (the head part 7, the component supply part 8, the XY table 9) in which the operation is completed is transmitted to the operation control device 1 through the external I / F 16 in the operation control device 1, and the operation is performed.

By the way, in the above-described conventional information sharing method, the operation control device 1 and the operation control device 2 refer to predetermined addresses of the bidirectional read / write medium 3 to each other so as to store information. Although shared, this method has a problem in that when one control device changes the address of the bidirectional read / write medium 13, the address recognized by the control device on the other side must also be changed.

Further, in order to realize the same operability for a plurality of models, even if the operation control device 2 of the same software is used, the bidirectional read / write medium 3 recognized by the operation control device 1 can be used. Since the address is fixed in each model, there is a problem that the software of the operation control device 2 cannot be shared.

In view of the above-mentioned conventional problems, the present invention makes it unnecessary to change the software of the other control device even when the address recognized by the software of one control device is changed, An information sharing method between a plurality of control devices and an electronic component to which the same operation control device can be used for a plurality of types of operation control devices to improve software development efficiency and quality It is intended to provide a mounting device.
