Control program automatic creation system

A control program automatic creation system, comprising

• a control program creator, having a block diagram data storage, an executable code storage, and a display;
• wherein the control program creator stores a block diagram which shows an arrangement of a plant instrument in the block diagram data storage, creates a control program of the plant instrument based on the block diagram which is stored in the block diagram data storage, and further stores the created control program in the executable code storage,
• a controller, having a process input output (PIO) device and a memory, the controller receiving a process signal from the plant instrument which is to be connected with the PIO device, and
• a network, connecting the control program creator and the controller,
• wherein
• the control program creator transmits the control program which is stored in the executable code storage by way of the network, and
• when the controller receives the control program by way of the network, the controller stores the control program in the memory, and further executes the control program, and transmits a computational decision of the control program by way of the network, and
• when the control program creator receives the computational decision of the control program by way of the network from the controller, the control program creator superimposes the computational decision on the block diagram which the display section displays and displays the superimposed decision.
