Except that is input, it functions in the same manner as the backup switch 61.

  Similar to the preliminary measurement control device 62, the permanent preliminary measurement control device 72 has the control logic of all the individual measurement control devices 18, and corresponds to the stopped individual measurement control device 18 when the individual measurement control device is stopped. The process signal A1 connected to the backup switch 71 via the connector cable 56 and input from the measuring instrument 11 to the stopped individual measurement control apparatus 18, and the storage of the backup switch 71 corresponding to the individual measurement control apparatus 18 The operation signal B2 stored in the device 63 is captured.
