In mode(s) Current programming You
scalers for total
(multiply/divide)
enter a multiplier and divisor here, separated by a (/) to have the module report
total counts in units meaningful to your application
(the multiplier must be ≤ the divisor)
RANGE: 0Ć32,767 DEFAULT: 1/1 (no scaling)
For example, if 15 counts represent 2 gallons, you could scale counts to gallons by
entering scalers of 2/15.
Scaling affects only the total counts value that the module returns in the BTR.
All programming in the BTW Ć- e.g. rollover value, output ON and OFF values is
still in Hz .
T, NRT
rollover value
enter a count value that the totalizer will reset or rollover to 0 at (when the unscaled
count reaches that value, the module sets the overflow status bit in the BTR and
starts counting again from 0)
RANGE: 0-9,999,999 DEFAULT (if you enter 0): 10,000,000
T, NRT
tied to outputs
see the output(s) that are currently tied to this input channel (this field is display
only Ċ to tie outputs to a different input channel, use the Output Setup screen.
all
reset total
see if the Total Reset (BTW word 1, bits 00Ć30) is ON (this field is display only). T
reset overflow
see if the Overflow Reset (BTW word 1, bits 04Ć07) is ON (this field is display only). T, NRT
start prover
see the current settings in the BTW data file (you must make any changes to this
field through a running program on the PLC processor, or by directly setting bits in
the BTW; you can not edit these fields with the I/O Configuration software)
T, NRT
prover type, uni
or bidirectional
press (F9) Ć Toggle to select the type of prover you are using in your application
0 = unidirectional 1 = bidirectional.
