3.2.1 Monitoring of Values by Polling the PA Buffer
The LOGO! PA buffer values are monitored in order to generate a fault message
when a value changes.
This monitoring is performed in the polling operation, that is, the INSYS GSM 4.2
LOGO! reads out the LOGO! PA buffer cyclically, thus enabling changes to be
detected.
The scan interval can be set in the seconds range (1 to 255 s).
If a change in a monitored value is registered, a fault message is transmitted
(SMS, SMS to fax, SMS to e-mail, SMS to conventional telephone).
In the case of digital values, the following events (selectable) can trigger
transmittal of a fault message:
- Change to 0
- Change to 1
- Any change
when a value changes.

- Change to 1

For analog values, an upper limit and a lower limit must be specified; in this case,
the following events (selectable) can also trigger transmittal of a fault message:
- Value leaves the specified range (lower limit to upper limit)
- Value enters the specified range (lower limit to upper limit)
- Any range change
the following events (selectable) can also trigger transmittal of a fault message:
- Value leaves the specified range (lower limit to upper limit)
- Value enters the specified range (lower limit to upper limit)
- Any range change
The fault message can have the following content (selectable):
- PA-SMS: An image of the PA buffer (utilized values) containing all current
- PA-SMS: An image of the PA buffer (utilized values) containing all current
values at the time of the change is received. Depending on the number of
utilized values in the PA buffer, the SMS can also be divided into multiple (up
to 3) SMS. This message cannot be sent as an e-mail.

- Text message with predefined message: This facilitates easier classification of
the change. A general message can be prefixed to each of these messages (e.g.,
with asset number, address, etc.).
