Abstract
A controller is provided with a first memory area and a second memory area, where a pre-update software is stored with the first memory area as the active area and an updated software is downloaded with the second memory area as an inactive memory area. A microprocessor for simulations performs a simulation of the control of the operation of a field device using the updated software that has been downloaded. The execution status of the simulation can be monitored using a host computer. If the evaluation result of the state of execution of the simulation by an operator is 'Pass,' then an activate command is sent to the controller. As a result, the active/inactive are switched in the controller.
