Holding Registers
Like the coils, spares are in place between the “standard” registers and those that are
designated as specific/optional. There are no specific/optional coils defined for the
MiniCapt.
If the sample setting holding registers are sent while the unit is sampling, it will ignore
the new settings until the next sample set is executed.
40001 - 40002:

Real Time Clock
Dual-register representation of current date & time.
Integer value (type defined as time_t) representing date/time in
seconds since January 1, 1970.
40003:

Sample Interval/Sample
Volume
Sample Interval/Sample Volume.
This register representation depends on the Sample Volume
Mode setting (coil 00/09).
When the Sample Volume Mode is disabled - this register
represents the number of seconds to run a sample. When the
Sample Volume Mode is enabled - this register represents the
volume in liters multiplied by 100.
40004:

Hold/Tare Time
Time, in seconds, processed between the pump coming up to
the specified flow and starting the first sample.
40005:

Repeat Count
Number of samples to process.
The value must be greater than 0.
40006:

Delay Time
Time, in seconds, processed between each sample.
40007 - 40032:

Spare
