    • PROBLEM TO BE SOLVED: To provide a process control method and device with maximum possible safety secured in a manner as simple and cost-favorable as possible.
      SOLUTION: At least one process unit to control is controlled by at least one process module and by at least one security module, process signals irrelevant to the security are transmitted from the process module and security signals relevant to the process security are transmitted from the security module respectively to a local control unit embedded in the process unit, the process signals and the security signals are logically linked to each other in the control unit, the process unit to control is connected to a control output of the control unit, and the result of the logical link is provided to the control output.

    • PURPOSE: To cope with high flexibility with the different input/output specifications or the change of specifications of a sequencer itself, by using a setting means to perform switching between the input and output means as well as the input and output point numbers and to set the answer time of the input.
      CONSTITUTION: A setting means 120 performs switching between the input and the output and sets the number of inputs and outputs as well as the answer time. An input control means 102 performs the input filtering to the input signal given from an external device read by a reading means 101 in response to said setting operation. Then the means 102 fixes the input state and stores this fixed state to the 1st memory means 103. This stored data is delivered to a bus 150 by a bus control means 130. While an output control means 112 supplies the data supplied from the bus 150 and given to the external device via a bus control means 130 and stores the data to the 2nd memory means 113. Then this data is delivered to the external device and held there.
