Control management device

A control management device comprising:

• a job input circuitry into which a job including a plurality of instructions to a controller is input;
• a controller exclusive determination circuitry configured to determine whether or not the controller which is a target of an instruction included in the job is locked due to an ongoing exclusive process by another job, and, when the controller is locked, wait for the controller to be unlocked;
• a parameter value storage configured to, when an instruction to be executed next is writing of an exclusive process, store a value of writing target in the controller as an original data value and lock the controller;
• an instruction execution circuitry configured to notify the controller of the instruction to be executed next in the job and cause the instruction be executed by the controller;
• a job completion determination circuitry configured to determine whether or not all instructions in the job have been completed;
• and
• a parameter value restoration circuitry configured to restore the original data value to the controller after all the instructions in the job have been completed and unlock the controller.
