ATU Configuration

No configurations are needed for the ATU. The device has already been configured with the use of the software OPTWin.

To add the unit in Avensor, prepare the following data.

Parameter	Location in the software OPTWin
IP address	Hardware Definition > Network > Network selection: GPRS Primary
Number of ports for each port type	I/O Configuration
Data point related to each port	I/O Configuration
For each port type: – Modbus base address – Function code	Hardware Definition > Modbus > Output Addressing
Input range for each analog data point *	Lower: I/O Configuration > Scale Low Upper: I/O Configuration > Scale High

Example: If the ATU is configured to scale the level sensor from 0 mm to 5000 mm, the input range in Avensor is set to “Lower: 0” and “Upper: 5000 mm”.
