PURPOSE:To record positively necessary plant data with fewer recorders by automatically changing over a message point for the recorders judging a plant condition based on information from a plant measuring point providing the device with a device for deciding a plant condition. CONSTITUTION:A device for deciding a plant condition 3 judges the plant condition by deciding satisfaction or non-satisfaction of each condition on a condition table based on a signal from the plant. According to this judgement the device 3 selects a process on a process table and outputs an operating signal (b) indicating a recording speed corresponding to the process and an operating signal (c) indicating recording items and recording range. A recording signal generating device 2 extracts data (d) in a necessary recording item among each plant data (d), converts them into a specified recording range, and outputs each recording signal (a). A recorder 1 records a plural recording signal in a speed based on the operating signal (b). |
