P-NET SWNo. 13: Temperature
This register can show the temperature, calculated using the Pt100 sensor connected to
the Flow Transmitter. If the four terminals for the temperature sensor are short-circuited,
the calculated temperature will be approx. -245 ° C, equal to -409 ° F. The calculation unit for
temperature is selected in the Code3 register.
P-NET SWNo. 14: Available
The Available register has several functions depending on the selected options for Output3
and Batch control / Limit switch:
•
If the Output3 function is set to current output with PI-regulator , the Available reg-
ister contains the output value from the regulator. The output value will be in the range
0 to 100%, corresponding to 4-20 mA or 20-4 mA, depending on the selection in the
PICode register. If the PI-regulator is in Manual operation, then a value may be written
into the Available register, giving the output value for the current output.
•
The Available register may be used as Data input for Batch control / Limit switch .
•
If none of the above options are selected, this register may be used as a free register
for storing Real values.
P-NET SWNo. 15: Volume1
This register can show one of the two internal volume counters in the transmitter. The
counter increments when the flow is positive and decrements when the flow is negative.
The read-out resolution (number of digits after the decimal point) on the PD 210 display unit
for the counter is chosen in the Code1 register. This read-out resolution also determines
the overflow value for the counter. The counter value uses a total of 6 significant digits in-
cluding the digits after the decimal point.
When the counter has reached its maximum, error code 07 is generated, and the counter
starts from 0 again. The maximum value for the counter is reached when all 6 significant
digits show the value 9. The corresponding volume depends on the counter resolution. If
the resolution is 3 digits after the decimal point and the meter size is inserted in m
mum will be 999.999 m
ter.
P-NET SWNo. 16: Volume2
The Volume2 counter is similar to the Volume1 counter, though error code 08 is generated
at overflow. Furthermore it is possible to clear Volume2 by means of Input1 or Batchstart.
P-NET SWNo. 17: Setpoint
The Setpoint register has several functions depending on the selected options for the PI-
regulator and Batch control / Limit switch:
