The number of preambles must be set even if the auto-preamble control is selected. The

preambles value will be used for the link initialization command which determines the

number of preambles requested by the device.

In most sensor networks, the controller is the primary master device. A hand-held

programmer is typically a secondary master device. Set the device type to primary unless

another HART primary master device is connected to the network.

The settings can be saved to EEPROM with the toeeprom function block.
