-1 is returned (step S12 in FIG. 4). Server terminal 2
Returns the screen HTML, and then the client terminal 1-1
The system waits for a request to receive the alarm information from (step S13 in FIG. 4).

Upon receiving the request for alarm information, the server terminal 2 activates the alarm conversion processing program 21 (step S14 in FIG. 4). The alarm conversion processing program 21 reads alarm information from the alarm history file 22 (step S2 in FIG. 5).
1) Convert the alarm information into an HTML document (step S22 in FIG. 5).

The server terminal 2 is the alarm conversion processing program 2
The alarm information HTML converted by 1 is returned to the client terminal 1-1 (step S15 in FIG. 4). The server terminal 2 activates the alarm conversion processing program 21 at the refresh interval transmitted at the alarm request (step S1 in FIG. 4).
6, S14).

After the complex multiplexer 3 is activated, it monitors a device fault or a transmission line fault, and if a fault is detected (step S41 in FIG. 7), it sends an alarm to the server terminal 2 (step in FIG. 7). S42).

In this way, the monitor control terminal program 23
The alarm information output by the device is stored in the alarm history file 22, and the server terminal 2 reads the alarm information at every refresh interval input from the client terminal 1-1 to monitor the alarm, and thereby the composite multiplexer 3 (alarm It is possible to realize the alarm monitoring without changing the configuration of the device which issues the alarm.

Further, the alarm information read from the alarm history file 22 by the alarm conversion processing program 21 is stored in the HTM.
By converting to an L document, the client terminals 1-1 to 1
Since the alarm information can be easily browsed by the WEB browser installed in -5, the alarm information can be monitored from any of the client terminals 1-1 to 1-5.

In the above-described embodiment, the system in which the five client terminals 1-1 to 1-5 are connected has been described, but the number of client terminals connected to the system is not particularly limited.

In this embodiment, the system configuration connected to one complex multiplexer 3 (device issuing an alarm) has been described, but the number of complex multiplexers 3 connected is not particularly limited. Similarly, in this embodiment, the system configuration in which one server terminal 2 is connected has been described, but the number of connected server terminals is not particularly limited.

Further, although the present embodiment has been described with respect to the configuration in which the compound multiplexer 3 and the server terminal 2 are network-connected, the type of the network connecting them is not particularly limited.

Furthermore, in this embodiment, the initial screen is shown in FIG. 8 and the alarm information screen is shown in FIG. 9, but this screen is an example, and there is no particular limitation on the contents of the screen.
The complex multiplexing device 3 that transmits various signals as a monitoring control target on the alarm information screen has been described, but it can be applied to any device as long as the device requires remote operation / monitoring by the monitoring control terminal. . At this time, the monitoring target is the alarm information, but any information output from the monitoring control terminal can be applied.
