PN 305200901, Rev YT
Register #0 holds the moisture concentration value not held during Verica-
tion. This value is in PPM.
A pair of registers #135 and #136 provide the same moisture concentration
value in oating point Modicon standard.
Register #1 holds the moisture concentration value held during Verication.
The units of measurement are changing depending of ag status located in
register #65.
A pair of registers #137 and #138 provide the same information in oating
point format.
Register #11 is a DataState register, which is designed to synchronize the data
acquisition process. This ag is cleared by read. A value of one indicates new
data is available.
Register #8 is the SystemState variable, which is set to alarms and warnings.
This value is decoded according to the table below.
Example:
If the value of SystemState is 12612, which is the sum of 4, 64, 256, 4096, and
8192 then the corresponding alarms are: Reading Alarm, Calibration Failure,
Flow Out of Tolerance, Moisture Generator Date, and Dryer Alarm, respec-
tively.
