Control apparatus

A control apparatus included in a distributed control system, comprising:

• at least one processor configured to:
• synchronize the control apparatus with another control apparatus included in the distributed control system in terms of time;
• control to receive information from the another control apparatus;
• add synchronization time information to the information and store the resulting information in at least one memory;
• set an area of the at least one memory according to a time difference of the information;
• select shared data from the information stored in the at least one memory;
• calculate a control command for a control target;
• store the selected shared data in the at least one memory,
• transmit the selected shared data;
• and
• calculate the control command for the control target based on the transmitted shared data,
• wherein the time difference of the information is a difference from an acquisition time at which the control apparatus acquires first information regarding the control target from a first sensor and another acquisition time at which the another control apparatus acquires second information regarding the control target from a second sensor.
