Abstract
A method of switching between a sequential control mode and other operation modes by mapping beforehand corresponding operating states with respect to operation tables provided for the different control modes of operation. When an operating state in the sequential control mode, in which a sequential control for plural operation processes on the basis of an SFC (Sequential Function Chart) is performed using programmable sequential controller, is switched to an operating state in a manual control mode or in an inching control mode, the corresponding operating state in the operation table is carried out immediately for the manual or inching mode of operation.
