Example 9: Selecting a Sample Gas:
TASK.
Set the analyser to operate on a sample gas, using the data provided in the “GasNew.csv” ile
(located on the customer coniguration disk). For the purpose of this example, the sample
gas selected will be air.
ACTION 1.
Write multiple holding registers (function 16). Register address = 162 (holding regis-
ter #40163) value = 4169Hex, Register address = 163 (holding register #40164) value =
7200Hex (Air0).
ACTION 2.
Set gas related coeficients. Coeficients can be obtained from the GasNew.csv ile located on
the Customer Coniguration loppy disk.
Register address = 74 (holding register #40075). Value = 998
Register address = 75 (holding register #40076). Value = 14000
Register address = 63 (holding register #40064). Value = 622
Next registers should be set for Dew Point temperature reading only.
Register address = 115,116. Value = 7.89E-04
Register address = 117,118. Value = -7.14E-06
Register address = 119,120. Value = 2.31E-08
Register address = 121,122. Value = -2.57E-11
ACTION 3.
Set process pressure to ixed 150 kPa
Write one holding register (function 06). Register address = 47 (holding register #40048).
Value = 1500Hex (multiplied by the scaling factor of 10).
Write one holding register (function 06). Register address = 48 (holding register #40049).
Value = 1500Hex (multiplied by the scaling factor of 10).
Example 10: Setting Veriication Schedule:
TASK.
Set the analyser to automatically trigger a veriication cycle. For this example, the analyser
will be set to perform a veriication cycle on the 3
rd
day of each month, at noon (12:00).
ACTION 1.
Set the veriication type to monthly.
Write one holding register (function 06). Register address = 81 (holding register #40082)
value = 3Hex (never = 0, daily = 1, weekly = 2, monthly = 3).
