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

 

malfunctioning), the 0x08 bit will be set.

 

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

 

0x0400: Space Line shorted to ground

 

0x0200: Blown Fuse

 

0x0100: No +48 VDC

 

 

GaugeStatus

Byte value indicating status of the gauge. Refer to the transmitter

 

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.

 

 

Raw1

Raw data from gauge. Value reported as hexidecimal value.
