Abstract
A field device (10) includes a detector (11) that detects a physical quantity and outputs a detection signal, a controller (121) that calculates, based on the detection signal, data for a measured trend indicating a temporal change in a parameter used for predictive diagnosis of the field device (10), and a memory (122) that stores the data. The controller (121) stores the data in the memory (122) at time intervals from the start time of measurement in the field device (10) to the current time and executes a compression process on the data stored in the memory (122) upon the amount of the data stored in the memory (122) reaching the upper limit of the storage capacity of the memory (122).
