4.9.2Application

The Emulator point (EMU) provides a communication interface between older tank gauging system and point blocks within the TankGate. Currently, the TankGate 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.
