PURPOSE:To elevate the reliability and to make it satisfactory economically, by connecting the master station of the telemeter equipment and the arithmetic control device, and executing the backup of the microcontroller. CONSTITUTION:In the figure, 11A is a signal line for connecting a master station 2 of the telemeter equipment and a microcontroller 3 by a bit parallel word serial signal, and likewise, 11A' is a signal line for connecting the master station 2 of the telemeter equipment and an arithmetic control device 4 by said signal. A distinctive feature of this invention is to have added said signal line 11A', and it can be realized easily by preparing in parallel two existing bit parallel word serial output signals for the master station 2 of the telemeter equipment. Accordingly, in the event of downtime of the microcontroller 3, the monitoring operation function by a monitoring operation console 5 is impossible, but the monitoring operation function which has used a CRT display device 6 is available, and the recording function such as tabulation by use of a typewriter 7 becomes available, as well. |
