PURPOSE:To execute easily setting corresponding to a monitor condition by setting discriminating data corresponding to segment data and selecting data corresponding to level data, in accordance with the own monitor object range, in each display device, and displaying an alarm data in accordance with each coincidence. CONSTITUTION:In display devices 31-3n dispersed in areas 11-1n and display devices 51, 52 of an area 4, discriminating data is determined in accordance with segment data and stored in a storage device. In the same way, selecting data is determined and stored in accordance with level data. In this state, transmission and reception of a data signal are executed in a transmission line 6, coincidence between the own discriminating data and received segment data is decided, and control devices to be received 21-2n are discriminated. Also, based on the level data which is sent in the next time, whether the display device is in a motor object range or not is discriminated by a coincidence of a control device to be received in the selecting data and a logical value in the corresponding level. |
