とが可能となる。Next, the operation will be explained below. The signal flow j at the operation console 3 or control console 4 slave station 81 is the same as in the operation explanation in FIG. The data is returned to the master station 2 along with other monitoring data. In addition, the operator console 3 and control console 4 can receive the setting device as a monitor signal using the same processing as other monitoring signals. In addition, even if the set value control is switched to the control console 4 (or 2 or 4), the current setting device is received from each other, so this setting device cannot be used. It is possible to maintain this condition and prevent sudden changes.
