Control device and control method

A control device configured to control a plurality of motors, the control device comprising:

• a first program executing unit that executes a sequence program for each control cycle;
• a second program executing unit that calculates an instruction value for each motor in accordance with a numerical control program;
• and
• a state managing unit that manages a control state correlated with a group including a plurality of predetermined motors of the plurality of motors,
• wherein the sequence program includes a control command for controlling a process of executing the numerical control program in the second program executing unit,
• wherein the first program executing unit gives an instruction relevant to execution of the numerical control program in the second program executing unit in accordance with the control command included in the sequence program, and
• wherein the state managing unit updates the control state based on at least one of the instruction from the first program executing unit and an execution state of the numerical control program in the second program executing unit.
