PURPOSE:To improve security and reliability of the operation of a control system operation by designing the titled controller that a central processing section does not complete a series of control operation so long as the control of other control variables is not finished even when only a signal control variable completes its control operation. CONSTITUTION:A selection control instruction detection section 4 detects whether plural control variables are controlled in parallel at the same time or only a specific control variable is controlled selectively. Control stop instruction detection sections 51-5n detect that a control variable receives a control stop instruction via sequence controllers 21-2n. The 1st control stop section 6 transmits a total control stop instruction signal 8 to a central processing section 1 when a parallel control instruction 4a outputted from a detection section 4 and total control end signals 5a, 5b outputted from the detection sections 51-5n are inputted. The 2nd control stop section 7 gives the signal 8 when a selection control signal 4b is inputted from the detection section 4 and only the specified control variable receives the control end signal 5a. |
