Abstract

PURPOSE:To enable to change the set value even if the sequence controller is in operation, by externally locating the external setter group outside the sequence controller. CONSTITUTION:A set value data signal 3b' is included in the sequence instruction 2a' read out from a program memory 2, it is inputted to an operation section 3, from which input is made to a set value selection section 7 and an external set readout section 10. The external set readout section 10 outputs the setter readout signal 10a as the address signal to the external setter group 9 according to the set value data 3b', only when the selection signal 3c is the signal selecting the specified setter of the external setter group 9. The set value selection section 7 selects either internal set value data 3b' or external data 8a, and transmits it as the set data 7a of the timer or counter to a timer and counter control section 4.
