In step S4, the contents of the e-mail defining the address of the recipient of the process mail and the address of the proxy recipient are reflected on the process mail control device 71.

In step S5, the contents of the e-mail defining the process information aggregation condition are reflected in the process information aggregation condition storage device 62.

After the necessary control conditions are set in this way, process data is obtained.

The operation of the process data transmitting apparatus according to the fifth embodiment when acquiring process data will be described with reference to the flowchart of FIG.

Step S1 shown in the flowchart of FIG.
Steps S1 to S14 shown in FIG.
1 to Step S14. Accordingly, here, the description will be made from step S14 onward, that is, from step S20.

When the process data transmitted from the mail transmitting / receiving device 81 of the process data transmitting device 1 is read by the recipient (S20: Yes), the content is confirmed by the recipient (S21), and
The flag of the option for recipient confirmation changes (S22),
This is confirmed by the process information distribution destination reception confirmation device 63.

As a result, it is confirmed that the process mail has been read by the recipient, and the transmission of the process data is completed (S23).

On the other hand, if the process data transmitted from the mail transmitting / receiving device 81 of the process data transmitting device 1 has not been read by the recipient (S20: No),
The flag of the recipient confirmation option does not change. If the flag of the option for confirming recipients does not change after a certain period of time, it is determined that the recipient is not able to read the mail due to absence etc., and the process is sent to the substitute recipient instead. An e-mail is transmitted (S25), and thereafter, step S20 and subsequent steps are repeated.

Note that the present invention is not limited to the above embodiment, and the process information aggregation condition storage device 62
In addition to the process information aggregation condition, the process information periodic aggregation condition described in the second embodiment described above, the process information event detection condition described in the third embodiment described above, and the process information event detection condition described in the fourth embodiment described above. By also defining the process information attachment conditions described in the embodiments, process data is regularly aggregated, process data is transmitted only when the operating state of the plant changes, and related information is It can also be attached to process data and sent to the receiving side. Furthermore, it is also possible to implement them by appropriately combining them.

As described above, in the process data transmitting apparatus according to the present embodiment, the process mail in which the recipient confirmation option is added to the plant data is transmitted to the designated recipient by the above operation. At the same time, it is possible to determine whether or not the designated recipient has read the process mail by checking the change of the flag of the recipient confirmation option.

When it is confirmed that the designated recipient has read the process mail, it is determined that the transmission of the process mail has been completed. On the other hand, when it is determined that the designated recipient has not read the process mail, , A process mail can be sent to the proxy recipient.

That is, the monitor can check the process data of the plant 5 at any place provided with the e-mail receiving equipment, even if the monitor is not provided with a dedicated monitoring control device or the like. Thus, the process data transmitting apparatus 1 can also recognize the confirmation state of the receiver.

Thus, for example, even if the receiver is absent or the like, the process mail is sent to the substitute receiver instead, so that the monitor can surely grasp the operation state of the plant 5. .

As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to such configurations. Within the scope of the technical idea described in the claims, those skilled in the art can come up with various modified examples and modified examples, and these modified examples and modified examples are also within the technical scope of the present invention. It is understood that it belongs to.

[0150]

As described above, according to the process data transmitting apparatus of the present invention, process data obtained from a plant can be transmitted to a monitoring side via a general-purpose communication network.

As described above, the process data of the plant can be obtained without using a dedicated monitoring and control device.
