Example 2: Setting the High-Alarm Limit:
TASK.
Set the analyser to produce a “high-concentration” alarm, when the moisture concentration
exceeds 1000 ppm.
ACTION.
Write one holding register (function 06). Register address = 66 (holding register #40067).
Value = 1000.
Example 3: Setting the Low-Alarm Limit:
TASK.
Set the analyser to produce a “low-concentration” alarm, when the moisture concentration
falls below 0 ppm .
ACTION.
Write one holding register (function 06). Register address = 67 (holding register #40068).
Value = 0.
Example 4: Enabling “Hold During Verify”:
TASK.
Enable hold the analog outputs at the last measured value, when the analyser is off-line to
perform a veriication cycle.
ACTION.
Write one holding register (function 06). Register address = 98 (holding register #40099).
Value = 1(0-track during verify, 1-hold during verify).
Example 5: Setting the High-End of the Analog Output:
TASK.
Setup the analog output so that a moisture concentration of 100 ppm produces a 20 ma cur-
rent output.
ACTION.
Write one holding register (function 06). Register address = 45 (holding register #40046).
Value = 100.
