Counter – Alarms View
Use Counter – Alarms to configure the alarms for the counter.
Counter – Alarms View Example
The Counter – Alarms view includes these parameters:
Parameter | Description |
|---|---|
Pulse Width Alarm Limit | Defines the maximum pulse width that is allowed before the pulse
width alarm is triggered. If the instantaneous or average pulse
width exceeds the maximum pulse width, the pulse width alarm is
triggered. |
Accel Alarm Limit | Defines the maximum acceleration rate that is allowed before the
acceleration alarm is triggered. If the instantaneous or average acceleration rate exceeds the
maximum acceleration rate, the acceleration alarm is
triggered. A value of 0 disables the Alarm. |
Decel Alarm Limit | Defines the maximum deceleration rate that is allowed before the
deceleration alarm is triggered. If the instantaneous or average acceleration rate is less than
the maximum deceleration rate, the deceleration alarm is
triggered. A value of 0 disables the Alarm. |
Frequency Alarm Limit | Defines the frequency limit that is allowed before the frequency
alarm is triggered. If the instantaneous or average frequency exceeds this limit, the
frequency alarm is triggered. |
Zero Frequency Alarm Limit | Displays the value that the frequency or average frequency must
be less than to trigger the zero frequency alarm. |
Latch Zero Frequency Alarm | Determines whether the zero frequency alarm latches so that it
does not clear until explicitly unlatched. |
Enable Missing Pulse Alarm | Determines whether the missing pulse alarm is enabled. |
Missing Pulse Alarm Limit | Displays the length of time that must elapse between detecting
the leading edge of consecutive pulses before the missing pulse
alarm is triggered. |
Latch Missing Pulse Alarm | Determines whether the missing pulse alarm latches so that it
does not clear until explicitly unlatched. |
Diagnostics | Opens the Diagnostics dialog, which contains diagnostic
information. |
