There is provided a field device for downloading a new software through a field bus from a host system and replacing a current software which is currently executed with the new software. The field device includes: a history information generation and management section which generates and stores history information of the current software when the new software is downloaded from the host system.

Process control systems may include one or more diagnostic systems and/or processes. In particular implementations, a diagnostic system and process for a field instrument may include the ability to divide a signal input range into a plurality of zones with respect to an input axis or a time axis, measure input response characteristics for a zone with the field instrument, and store measurement data points for the zone in memory of the field instrument. The diagnostic system and process may also include the ability to transmit the measurement data points for the zone to a host application and, while transmitting the measurement data points for the zone, measure input response characteristics for a second zone with the field instrument.

摘要:
The present invention provides an off-line diagnosis system whereby the measurement resolution (number of measurement points) can be increased in order to obtain detailed input-output characteristics, and step response characteristics can be obtained at a sufficient frequency and more efficiently, without expanding the physically limited memory capacity of a field instrument or host application. The off-line diagnosis system comprises a field instrument that performs process control and has a self-diagnosis function or a valve diagnosis function and a host application that performs digital communication with the field instrument, wherein the self-diagnosis of the field instrument is executed or the diagnosis of a valve is executed during an off-line interval and diagnosis results are transmitted to the host application, and wherein the signal input range of the field instrument or the valve is divided into a plurality of zones with respect to the time axis or input axis, and the diagnosis results of each zone are successively transmitted to the host application.
