A setting systemincludes a device configuration database DBthat stores setting data in a first format in which a device parameter to be set to a field deviceand identification information that logically identifies the device parameter are associated, and for which authority prescribed in advance is required in order to change the stored data, and in which, using device configuration information specifying the physical structure of the field deviceand the setting data in the first format obtained by reference to the database DB, setting data is generated in a second format in which physical information specifying the physical address at which the device parameter is to be set is associated with the device parameter, and is set to the field device. According to this setting system, it is possible to perform exchange of a field device without any requirement for engineering by a system engineer, thereby avoiding a device in production efficiency.

The invention achieves a communication quality diagnostic unit capable of detecting an omen phenomenon of a communication trouble early in a stage prior to actual emergence of the communication trouble due to a noise, thereby issuing a warning. The communication quality diagnostic unit for diagnosing quality of communication for transmitting and receiving frames at predetermined interval time, comprising a frame-interval time detector for monitoring interval time between the frames, a frame-interval abnormality determiner for making determination as the case of diagnostic abnormality when a predetermined threshold value is exceeded by frame-interval time as detected, and a diagnostic abnormality notifier for notifying a host unit of the diagnostic abnormality as an alarm.
