Abstract

PURPOSE:To supplement the deficiency of a timer in a user program side by providing a timer element in a CPU unit, providing the timer element in a temporary storing means and setting a timing by both the elements. CONSTITUTION:At the time of turning on a contact 1 for indicating the initialization of the extended timer, a designated device except the timer is designated by a first SUB instruction 2 and the timing of the device is set to a device memory according to a MOV instruction 3. When the device designated according to the first SUB instruction 2 is the device of a coil 6, at the time of turning on the contact 5 of an input condition, the coil 6 is turned on. A second SUB instruction 4 detects the on state of the coil 6 in the executing cycle of a next sequence program and starts to count a time. When this counted value is a numeric value set by the MOV instruction 3 or exceeds the numeric value, an operation for turning on a contact 7 is executed by a program called by the second SUB instruction and an output coil 8 is turned on according to the condition of turning on the contact 7.
