2.4Teleservice via PC

A Mitsubishi Alarm Modem can be used to handle the remote maintenance of several controllers via a telephone line. This is usually possible with the program- ming software in use. The variables and I/O ports of the PLC can also be read or written remotely online with the Mitsubishi Alarm Editor (MX-AME). The entire configuration of the Mitsubishi Alarm Modem can be carried out by remote dial-in and the logged data can be read “manually".

Secure Login

Optimum security is ensured since unauthorized dial-in attempts are prevented by means of a login procedure with user name and password. All dial-in and dial-in attempts are recorded.

2.5Pump alarm application example

The following example shows how you can use the wide range of functions of the Mitsubishi Alarm Modem to handle complex tasks automatically:

Pump alarm:

Send an e-mail, a fax and an SMS to three different destinations if input X0 on the PLC closes.

Wait ten minutes for a confirmation via SMS.

Service technicians can query status values by SMS (or dial-in and PC).

Wait for a switch command for reserve pump 2.

If the SMS confirmation does not come within 10 minutes, start a new alarm message cascade to other recipients.

If the switch command for switching on the reserve pump has been received, switch on the PLC output Y10 (or a relay).

2.6Model And Equipment Versions

The Mitsubishi Alarm Modems were offered in two equipment versions: GM series (Alarm Modem GSM) and AM series (Alarm Modem 56k ). The basic functions within these series are identical.
