PROBLEM TO BE SOLVED: To provide a programmable controller capable of easily rewriting a program in a short time.SOLUTION: There is provided a programmable controller including a first storage part 17 which stores a sequence program defining the operation of a controlled system, an arithmetic processing part 10 which executes the sequence program so as to control the operation of the controlled system, and an interface 30 which can make a communication connection with the outside. The arithmetic processing part is set in one of a normal mode in which the operation of the controlled system is controlled using the sequence program, a rewrite mode in which the sequence program stored in the first storage part is permitted to be rewritten, and an output mode in which the sequence program stored in the first storage part is output from the interface so as to rewrite a sequence program of another programmable controller. |
