Abstract
A non-transitory computer readable-medium storing a compiler to cause a computer to perform processing for compiling sequence programs including a declaration of a global variable and generating an execution program to be executed by a PLC. When there is a change in a memory address in the PLC assigned to the global variable between before and after edit of a declaration of the global variable, the compiler gives an execution code to synchronize a first value stored at a memory address assigned to an unedited global variable with a second value stored at a memory address assigned to an edited global variable to an execution program corresponding to the sequence program that references the edited global variable.
