DensityUnits Specifies the engineering units for the density data.
K: kg/m3
A: API
L=lbs/cu ft
G= g/ml
The DensityUnits needs to match the units specified during the gauge setup.
The Density can be converted from Metric to English (or vice-versa) by setting
the DensityConvert parameter in the appropriate MSCAN or RKSCN point.
LevelDeadband The LevelDeadband sets the deadband for the Change of State mode. The
default is 0.
TempDeadband The TempDeadband is used to set the Change of State deadband for the
temperature. The default is .25 degrees.
FastScanMode Places the SG6000 point in the Fast Scan mode. Values are Enable or Disable.
BaudRate The default is 19200.
Report Causes automatic notification to the Host (in response to a Change of State
Request) when the Level, Temp, Position changes. Parameter value can be High,
Low or No. Report=No disables automatic notification. Points with Report =
High will be sent before points with Report = Low. The default is High.
Maxtime Specifies the maximum time (in secs) between automatic Change of State
responses being sent to the Host. Report must be set to either Low or High for
the Value parameter to be sent in response to a Change of State Request. A
value of 0 disables this option. Non-zero values cause responses to be sent
even if the value has not changed since the last message. The maximum is
65535 seconds. The default is 240.
Watchdog Enables the watchdog task on the Motherboard. The watchdog task monitors the
SG6000 point and verifies it is scanning for gauges.
Dynamic Parame-
ters Function
Command The Command parameter allows you to issue a single command to the gauge. Valid
commands include:
Bottom: Commands the gauge to find and follow the tank bottom
Find Wtr Level: Commands the gauge to find the water level (upper interface), then
return to product level
Run Immed Profile: Commands the gauge to perform a density profile (manual I/F
profile)
Test: Commands the gauge to perform the Repeatability test
Mid Int Level: Commands the gauge to find and follow the middle interface level
Middle Density: Commands the gauge to perform a measurement of the middle
density
Follow Level: Commands the gauge to find and follow the product interface level
Raise: Causes the servo to raise
Reset: Resets any command issued and commands the servo to Follow Level
Stop: Stops the servo from raising or lowering
Follow Wtr Lvl: Commands the gauge to find and follow the water interface (upper
interface) level
Upper Density: Commands the gauge to perform a measurement of the upper
density, then return to product level
