Definition
Enables the Overrange alarm on output connected to channel 0. When
the Frequency Period exceeds 100 KHz, this alarm is set.
0 = No Alarm
1 = Alarm Enabled
Enables the Overflow alarm on output connected to channel 0. When the
Total Counts exceeds the Roll Over value, this alarm is set.
0 = No Alarm
1 = Alarm Enabled
Enables the Overspeed alarm on output connected to channel 0. When
the Speed exceeds the Highest Allowed Frequency value, this alarm is
set.
0 = No Alarm
1 = Alarm Enabled
Enables the Acceleration alarm on output connected to channel 0. When
the absolute acceleration exceeds the Acceleration Alarm value, this
alarm is set.
0 = No Alarm
1 = Alarm Enabled
Rising edge resets the count
We recommend that you latch the <tagname>O.ResetCounter.(0-1) bit
and unlatch that with the <tagname>I.WasReset.(0-1) bit.
• When the <tagname>I.WasReset.(0-1) bit will remain on until the next
time, the <tagname>O.ResetCounter.(0-1) bit is turned on.
• When the <tagname>O.ResetCounter.(0-1) bit goes high, the
<tagname>I.WasReset.(0-1) goes low until the
<tagname>I.StoredValue.(0-1) equals 0.
At that time, <tagname>I.WasReset.(0-1) will go high again. The toggle
from On to Off is done quickly and you may not see it in the controller.
Reserved
Enables the prover operation on output connected to channel 0. Once this
bit is enabled, the module waits for output Z
beginning prover operations.
0 = Prover operation is disabled
1 = Prover operation is enabled
Enables the filling operation on output connected to channel 0.
0 = Fill operation is disabled
1 = Fill operation is enabled.
Begins filling operation when Fill Enable is enabled on output connected
to channel 0.
0 = Do not begin filling
1 = Begin filling
Holds/pauses filling operation on output connected to channel 0
0 = Continue filling operation
1 = Hold/pause filling operation
Sets the user-defined rollover value on output connected to channel 0.
Range of 0 - 2,147,483,647
Unitless factor that is multiplied by Gross Rate with results shown as
NetRate of channel 0.
This value must be set to 1.0 when not used or gross rate will be 0.
Calculation Type must be set to 0 to use this factor.
Temperature in °F of output connected to channel 0
Temperature in °F of output connected to channel 0
Pressure in psia of output connected to channel 0
