Configuration using the PC

3-7

Enabled

When a point is enabled, alarm activities will be reported and it can be interrogated for its current status. A disabled point does not produce alarms and cannot be interrogated. Changing the enable flag does not alter any of the other settings for this point.

Default Point state: disabled.

Digital and Watchdog Points

Settings for Watchdog points are the same as for Digital points.

Alarm State

Points can be set to register an alarm in two ways: only when the alarm condition is present, or latched when an alarm condition is first detected. Latched operation means that the alarm is set when the input change is first detected and will remain in that state until the group it is using is acknowledged. If the alarm is not latched, it will be removed as an alarm when the input condition returns to normal.

Default alarm state: when active.

DTMF Tag

The DTMF Tag is used to generate signaling messages for remote equipment. If a DTMF tag is available, it will be sent if the [SIGNAL] command is present in the Directory.

The tag can consist of 1 to 7 digits and may use any of the 16 DTMF digits including A, B, C, and D.

Default DTMF Tag: empty string - no signaling.

Interval Point

An Interval Point uses only the common settings. It cannot generate alarms, but can be interrogated to obtain readings.

Totalizer Point

Totalizers cannot generate alarms, but can be interrogated to obtain readings. In addition to the common ones, the totalizer also has the these settings:

Decimal Place

A decimal place can be inserted into the spoken message for a totalizer. Five decimal locations are available:

XXXXX.

XXXX.Y

XXX.YY

XX.YYY

X.YYYY
