30001:
Modbus Map Version
This is a fixed value representing the version number of the Modbus
map multiplied by 100. This version will change if/when the basic
structure of the map and/or processing associated with the
structure of the map is adjusted.
NOTE: Additions and/or definitions to the spare entries will not
generally require a version change – they will simply be
annotated as to the applicability to that particular
instrument. The same reasoning is applied to unique
registers and/or coils for a particular instrument – they will
simply be annotated as being specific to that device.
30002:
Sensor Firmware Version
This is a value representing the version number of the flow
controller firmware multiplied by 100.
30003 – 30010:
Product Name
Product name entered using ASCII bytes and positioned as shown
in the map.
30011:
flowrate Scale Factor
The power of 10 multiplied to the flowrate and then entered into
registers 30013/30014, 30222/30223 and 30229/30230. Used when
the floating-point representation is disabled. The MiniCapt uses a
value of 2 to represent a fixed scaling factor of 100 for flowrate.
30012:
Volume Scale Factor
The power of 10 multiplied to the volume and then entered into
registers 30224/30225 and 30231/30232. Used when the floating-
point representation is disabled. The MiniCapt uses a value of 5 to
represent a fixed scaling factor of 100000 for volume.
30013 – 30014:
flowrate
Dual-register representation of the nominal flowrate in liters per
minute. Can be integer or float depending on mode selected. The
integer representation uses scale factor from register 30011.
30015:
Number of Particle
Channels
Processed as a variable but fixed to a value of 0 for MiniCapt.
30016:
Number of Analog Channels
Processed as a variable but fixed to a value of 3 for MiniCapt.
30151 – 30152:
Sensor Firmware Version
This is the main firmware version for the MiniCapt. Each byte
represents an element of the version as shown
-4.
