Abstract

PURPOSE:To shorten an execution time without changing the sequence language used up to this time, by providing a storage area for storing the next jump destination, when there is dissidence in an input condition. CONSTITUTION:A sequence controller is constituted of a CPU11, a sequence program storage area 12, a jump destination address storage device, and an interface 14 for controlling an external device 15. On this controller, a storage area 13 for storing a jump destination address is provided so as to jump to the head of the next line in case when there is dissidence of conditions, in AND of the input conditions for constituting a sequence program. In this way, the execution time can be shortened without changing the sequence language used up to this time.
