Coils
Like the holding registers, spares are in place between the “standard” coils and those
that are designated as specific/optional. There are no specific/optional coils defined
for the MiniCapt.
00/01:
The data collection coil will enable/disable sampling.
00/02:
The data available coil is used to both inform the host that data is now available and to delete the
queued data packet (if present).
00/03:
The data clear coil will delete all data in the queue.
00/04:
The reset sensor coil will reset the sensor.
00/05:
Green Status LED. Not applicable for MiniCapt.
00/06:
Red Status LED. Not applicable for MiniCapt.
00/07:
External Alarm. Not applicable for MiniCapt.
00/08:
IEEE-754 Float. IEEE-754 Float. The float control will change the specified registers from a dual-
register integer with fixed scaling to a dual-register IEEE-754 float representation. The IEEE-754
version is likely to yield better resolution but it is not part of the official Modbus specification.
00/09:
Sample Volume Mode. The sample volume control will change how the unit controls sampling. If set,
holding register 40003 will contain the sample volume to be processed multiplied by a factor of 100. If
clear, holding register 40003 will contain the sample interval to be processed in seconds. This value
can also be changed from the display. It is recommended that the coil selection be set every-time the
holding registers are sent.

If the queue size setting has been set to one, the sample data will always represent the
last real-time data packet and the data deleted will be the only data present.
If the queue size setting is set greater than one, the oldest data packet in the queue will
be deleted.
