PROGRAMMABLE CONTROLLER SYSTEM, SUPPORT DEVICE THEREOF AND PROGRAMMABLE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a programmable controller system capable of easily transferring common variable data in programmable controllers to a common memory.SOLUTION: A compiler section 12 assigns a desired address of an internal memory 25 to respective variables of source codes 14 when performing compilation processing; and further, an arbitrary address of a common memory 21 is assigned to each of the common variables in the variables to generate a variable information management table 17 which includes the pieces of address assignment information and a piece of information representing whether or not each of the variables is common variable. A transfer processing section 24 of the PLC 20 transfers the common variable data in the variables from the internal memory 25 to the common memory 21 by using the variable information management table.
