Method and system for validating a control program for an automation system, wherein the control program is created in a first controller programming language and is arranged and setup to control an apparatus or device of the automation system when executed by an automation controller of the automation system, where the system includes a controller environment for executing the control program, an equipment simulation environment for executing a simulation program for simulating behavior of the apparatus or device or parts thereof, whereas the equipment simulation environment is communicatively coupled to the controller environment to enable and/or perform a simulation of the automation system, and whereas the simulation program is created in the first controller programming language or a second controller programming language.

A control apparatus includes driving means for rotationally driving a predetermined mechanism, braking means for braking the driving means by pressing a pressing unit against a rotation unit of the driving means, and control means for, in order to change rotation position of the predetermined mechanism, controlling the driving means in a braking release period in which the pressing unit is returned to a predetermined position to temporarily maintain the rotation position of the predetermined mechanism, and then driving the predetermined mechanism to thereby change the rotation position. The control apparatus performs at least one of notification to the user, braking of the predetermined mechanism, and stopping of the driving means when a command time for the driving means at the time of temporarily maintaining the rotation position of the predetermined mechanism is longer than or equal to a predetermined time.
