Summary:An environment for easily executing a plurality of types of programs in cooperation with each other is provided. A control device (100) includes: a first program executing unit (10) that executes a sequence program (30) for each first control cycle (T1) and calculates a first instruction value (14); a second program executing unit (12) that executes an application program (32) which is described in codes which are sequentially interpreted and calculates a second instruction value (16) for each first control cycle (T1); and a shared memory (20) configured to be accessible by both the first program executing unit (10) and the second program executing unit (12). The second program executing unit (12) executes the application program (32) while referring to the first shared variable value (18) stored in the shared memory (20) in accordance with the codes described in the application program (32).
