Abstract
When a general-purpose operation part () is hidden by a window part (), it becomes hard for an operator to visually check an association state between a field device (A,B) and a hardware switch (). If such a display state has occurred, an HMI server () stops a health check signal which is being output to a PLC (). The PLC () detects the stop of the health check signal and forcibly cancels the association state between the field device (A,B) and the hardware switch (). Thus, a human error can be prevented.
