Abstract
An output unit, an input unit and an input-output system are provided to construct a safety control logic having a high degree of freedom in design and has scalability. The output unit includes an input signal receiving part, receiving an input signal from the input unit; and an output control part, performing an output based on the input signal. In each group set for the output unit, the output unit performs the output when receiving the input signals from all the input units set to the same group as the group set for the output unit.
Claims3
An output unit, capable of communicating with a plurality of input units, and more than one group is set for the output unit and each of the input units, and the output unit comprising:
- an input signal receiving part, receiving an input signal from the input unit;
- and
- an output control part, performing an output based on the input signal,
- wherein in each group set for the output unit, the output control part performs the output when receiving the input signals from all the input units that are set to the same group as the group set for the output unit.
An input unit, capable of communicating with an output unit, and the input unit being capable of group setting, and a value of an input from the input unit and information of the group setting being transmitted to the output unit.
An input-output system, integrating and outputting information from a plurality of input units, the input-output system comprising:
- the plurality of the input units and an output unit,
- wherein the plurality of the input units transmits values of inputs from the plurality of the input units and information of group setting to the output unit,
- the output unit receives the information transmitted from the plurality of the input units, and
- the output unit performs an output when receiving input signals from all the input units that are set to the same group as a group set for the output unit.
