Chapter 5 Configure the Configurable Flowmeter Module
C.OutputSetup[0].TieToCounter
Ties a channel to output 0
0 = No connection
1 = Connect Channel0 to Output0
2 = Connect Channel1 to Ouput0
0
C.Ch0ProverDirection Decimal BOOL
Defines the direction of a prover connected to Channel 0.
0 = unidirectional prover
1 = bidirectional prover
0
C.Ch0LowFreqClear Decimal BOOL
Enables the minimum detectable frequency level for
Channel 0.
Set the bit to 1 to enable it
1
C.Operations[0].OperationalMode Decimal SINT
Sets the module’s operational mode.
0 = OFF
1 = Totalizer Mode
2 = Non-Resettable Totalizer Mode
3 = High Resolution Frequency Mode
2
O.OutputControl[0].0 Decimal BOOL
Manually sets the operation of outputs connected to
channel 0.
0 = Module operation of outputs
1 = Override Output0 to 0
2 = Override Output0 to 1
0
O.Total[0].ProverEnable Decimal BOOL
Enables the prover operation on output connected to
channel 0. Once this bit is enabled, the module waits for
output Z
0
to energize before beginning prover operations.
0 = Prover operation is disabled
1 = Prover operation is enabled
0
O.Total[0].Overrange Decimal BOOL
Enables the Overrange alarm on output connected to
channel 0. When the Frequency Period exceeds 100KHz,
this alarm is set.
0 = No Alarm
1 = Alarm Enabled
0
O.Total[0].Overflow Decimal BOOL
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
0
O.Total[0].Overspeed Decimal BOOL
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
1
O.Total[0].Acceleration Decimal BOOL
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
1
I.Status[0].ProverState Decimal SINT
Displays status of the prover operation on channel 0
0 = Prover Not Active
1 = Prover waiting for 1
st
start
2 = Prover waiting for 1
st
stop
3 = Prover waiting for 2
nd
start
4 = Prover waiting for 2
nd
stop
5 = Prover Complete
I.Status[0].TotalCounts Decimal DINT
Displays actual pulses counted by the counter connected
to the channel 0
I.Status[0].FreqAverage Float REAL
Displays frequency averaged over the Meter samples on
channel 0
I.Status[0].FreqPeriod Float REAL Displays frequency using sample time on channel 0
I.Status[0].Speed Float REAL Displays frequency using filter resolution on channel 0
