• and
• specifying a transmission cycle at which an error between a difference between the end time and the start time and the specified transmission cycle is within a prescribed range.

A communication control apparatus comprising:

• an execution unit configured to execute a prescribed command at a specified transmission cycle;
• an acquisition unit configured to acquire a start time at which the execution is started and an end time at which the execution is ended;
• a performance unit configured to perform the execution and the acquisition while changing the transmission cycle;
