INFORMATION SHARING METHOD BETWEEN A PLURALITY OF CONTROLLERS AND ELECTRONIC PARTS MOUNTING DEVICE

摘要

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.
