11.3.2 ASD Scan Register Configuration

Scan Register Setup Information:

•Scan register values refer to ASD registers, NOT Modbus registers.

•There are 8 possible scan register values for each of the 3 channels. Not all 8 values need to be configured. The ETH-100 will only mirror those scan registers that have a displayed value.

•Each active scan register must be configured as read or write.

!A read scan register will be continuously polled from the ASD.

!A write scan register will be continuously written to the ASD. When a new write scan register is added to the list, or when a write scan register value is changed, its internal write value will be set to 0 for safety.

•To clear a scan register value, the user must CLEAR the value displayed on the web page interface and click apply.

•To add a new scan register value in an empty location, the user must enter a valid hexadecimal number, provide read/write information using the drop-down box, and click apply.

•Scan register values that are already displayed can be changed without providing a read/write value. The previous read/write value will be retained in this case.

•Scan register values and read/write values are stored in non-volatile flash memory, and will be saved when the unit is powered off.

•Refer to section 10.5 for more information about ASD scan registers.
