Abstract

PURPOSE:To enable to step forward manually on the way of stepping, when a program is being operated automatically. CONSTITUTION:An external control input 33 is constituted of a block selection input and a control input so that each block is operated separately from the outside by combining both said inputs. When a ''STOP'' input becomes ON, operation is stopped at a step which is being executed, and an output becomes all OFF. The internal state, however, is held as it is. When a ''START'' input turns to ON, the operation is started from a step which is being displayed, in accordance with a program, and in case when a step is different in each block, the operation is started from each different block. When a ''P-STOP'' input becomes ON, a step-forward of a process counter is stopped at a step which is being executed, and an output state and a state of a count timer, etc. are held as they are. When a ''STEP'' input turns to ON, the process counter is stepped forward by 1 step at every time, accordingly, contents of display, an output state, etc. are varied.
