8300		8315 L&J Tankway Software Description
	Configuration	Function
	Parameters
	TempOffset	Specifies the amount of offset to add to the Temp. The default is 0.
	Report	Causes automatic notification to the Host (in response to a Change of
		State Request) when the Value changes State. Parameter value can be
		High, Low or No. Report=No disables 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 255 seconds. The default is 60.

Dynamic Parameters	Function
Level	Floating point value representing the tank level. The Level will be
	presented in decimal feet or meters, depending upon the LevelConvert
	parameter of the
	WVSCAN point.
Temp	Floating point value representing the tank temperature. The
	Temperature will be presented in Fahrenheit or Celsius, depending
	upon the TempConvert parameter of the WVSCAN point
Alarm	Gauge Alarms. Not used for the GS2000 point.
PntStatus	Integer HEX value indicating status of point. Values are:
	0x0001: Gauge Not Responding. The first time the gauge does not
	respond, the 0x08 bit is set. On the second try, the 0x01 bit is set.
	0x0002: Parity Error on last scan
	0x0004: Data from the Gauge is Not Valid
	0x0008: Timeout Error. The Motherboard monitors the Elapse
	parameter. If data is not being updated (due to the 8210

	0x0010: Gauge did not respond on last scan (pre-fail)
	0x0020: Invalid Level
	0x0040: Large change in Level or Temperature
	0x0800: Mark Line shorted to ground

	manual for details on the GaugeStatus
	0x01: Temperature is out of Range
	0x04: Temp Sign
	0x08: X100 Temp bit
Elapse	Time of the last Change of State
PntCheckSum	CRC-16 Checksum for point's static Configuration Parameters.
