In MELSEC-Q series, in that, I introduce the mail function though it is a PLC into which the function to consider the Internet is plentifully built.

Mail function |
Are you used, though are installed the mail function in Ethernet unit "QJ71E71" of MELSEC-Q series? I think that become accustomed in respect "Using mail", "in using to mail" is on daily routine job.
"When trouble happens on the site, I want to send information on equipment to the specified mail address"
It is very convenient to send automatically information on the trouble from the site.
Then, how do we use the mail function? In the helped control board maker might be a little difficult, and in the software house that the OA system studies a little, could be understood. It is difficult problem where to consult, too. Moreover, even if E-mail is understood that is soft shop of the OA system, about equipment might not be understood at all.
The usage of the mail function has in generally two types. One is a usage "It wants you to be able to read trouble information by using the Internet at home PC". Other is a usage of constructing "small scale LAN" at each equipment and setting up the mail server there.
It is possible to send to the mobile phone by using for the Internet like the former. If it does so, up to date version of "the warning monitoring system" that uses the "pocket bell" and "the announcement", make complete. However, though the mail function of a now Q series is a specification of sending information as an attached file, the "I mode terminal" cannot read the attached file.
Moreover, with the exception of "I mode terminal", how does it so that mail may send to outside the company like PC at home etc? It is necessary to set up the mail server that can send to mail outside. However, because there is difficult problem like the installation of "global domain registration" and "the firewall" etc. And all company needs to cooperate like "the information system management section etc". Because only the staff of the production facility is difficult.
It is possible to set unexpectedly it up easily if there is only a person who can set up the server, because is only a network in the closed specific area. Perhaps, We make surly, many people who use the mail function is selected this.

Then, we introduces that the Ethernet unit is installed in PLC. According to the scale, the cost of hardware grows. Because the explanation becomes long, about small scale LAN explains here. Because in large scale, the management of the network address becomes very pain, and it is necessary to think about an efficient system by combining with the FA network such as MELSECNET.

Only because the setting up of MELSEC side sets a necessary item on the network parameter screen of GX Developer, the setting that looks like at general E-mail software is needed, though it thinks that it is not difficult. Concretely, transmission server (SMTP), reception server (POP3), and the mail address, etc. are setup like a left screen.
A difficult problem like a server name had better commit the person who setup the mail server. Small scale LAN operates if IP address of the mail server have only to input.

About the setup of the mail server, Microsoft Exchange and Netscape Communicator, etc has only to install Server.
To setup the above mentioned system, when the trouble occurs, as the mail can automatically send from MELSEC, we think that it can use it for various usages that "the maintenance management system", "the warning monitoring systems" transmit the device data as mail.
