Software Description Tank Gate Interface
32 Installation and Operations Manual
Application
The Emulator point (EMU) provides a communication interface between older tank gauging
system and point blocks within the 8203 Dual RS-485 Communications Interface Module .
Currently, the 8203 Dual RS-485 Communications Interface Module can emulate a Whessoe
Varec Model 6810 Tank Scanning Unit (TSU).
The EMU point associates a tank gauge point with an address to by used by TankView. EMU.0
provides point references for TankView System Addresses 1-50. EMU.1 is associated with
System Addresses 51-100. A EMUGW gateway point is automatically created when the protocol
for a COM point is set to TSU Slave.
TempUnits Specifies the engineering units for the temperature data.
TempUnitsSpecifies the engineering units for the temperature data.
F: Fahrenheit
C: Celsius
The TempUnits needs to match the units specified during the gauge
setup.
DensityUnits Specifies the engineering units for the density data.
DensityUnitsSpecifies the engineering units for the density data.
K: kg/m3
A: API
L=lbs/cu ft
The DensityUnits needs to match the units specified during the gauge
setup.
Offset Specifies the offset to the first address.
PntRef1 - 20 Input point reference for the EMU point to monitor. The PntRef parameter
is set to the Level parameter for the tank gauge point. The temperature
will be read at the same time as the level. The EMU point interfaces tank
gauge interface points:
