The effect of the present embodiment will be described. As described above, in the electronic manual display device, the monitoring device, and the electronic manual display method according to the embodiment of the present invention, the contents of the system alarm and the pages, chapters, sections, sections, etc. attached to the electronic manual in advance. When a system alarm occurs,
At the request of the observer, the relevant page of the manual relating to the alarm that is occurring can be displayed quickly without any additional operations.

[0096] Therefore, since an appropriate measure can be taken promptly, there is no need to troublesome and inquire the manufacturer. Similarly, since the tag is associated with the paragraph information on the page, chapter, section, section, etc. attached to the electronic manual in advance, when a process alarm occurs, the corresponding page of the manual related to the alarm being generated is superfluous. It can be displayed quickly without any operation.

Next, since the host document server 3 serving as the first document server is provided in the host system 1 of the maker that has created the control system, it is possible to quickly respond to frequent renewal of the system.

Therefore, maintenance becomes easy, and the user can always refer to the manual in the latest state. In addition, it is possible to display an appropriate countermeasure for a system alarm that is difficult for the monitor to understand.

Next, since the electronic manual is provided in the host document server 3 and the local document server 5, it is possible to solve the shortage of the hard disk capacity in the monitoring apparatus caused by holding the electronic manual.

Next, since the monitoring device 7 having the electronic manual display device body 6 and the host document server 3 are connected via the public line 2, the host document server 3 can be shared.

Therefore, it is possible to prevent an increase in the number of devices caused by the introduction of the electronic manual display device, an increase in cost associated therewith, and difficulty in maintenance, thereby facilitating the introduction of the electronic manual display device. In particular, when only an electronic manual for a system alarm is required, it is only necessary to connect to the public line 2 and there is no need to introduce a special document server, so that an inexpensive system can be constructed.

Next, since the electronic manual registration means for the local document server 5 is provided, the monitor can create and display the most appropriate electronic manual for the process alarm.

Therefore, it is possible to read out an appropriate countermeasure for a process alarm having different types and different contents for each control system or for each field of the control system. Therefore, even an inexperienced observer can perform the same judgment and coping with a mature person.

In addition, this makes it possible to make the contents based on the effective knowledge obtained through the work accumulated up to now into a database, and to make new information manual while the storage is new. Disappears.

In addition, in a case where a new device such as a printer is added to the local system in each control system, for example, when there is no electronic manual information of the device to be added in the document server 3 of the host, the host is replaced with the host. By installing the manual information in the local document server 5 in this way, it can be easily handled.

Further, the alarm can be used as an electronic manual without associating the manual with the alarm.
By doing so, it is possible to display and register as a normal document such as a function manual and an instruction manual regardless of the abnormal time.

The present invention is not limited to the above embodiment, but can be variously modified without departing from the scope of the invention. For example, in the present embodiment, the public line 2 is used, but the present invention is not limited to this, and another line such as a dedicated line may be used. Furthermore, in the present embodiment, the electronic manual display device main body 6 is incorporated in the monitoring device 7,
Dedicated hardware may be provided.
