Configuring the Island Bus

The RST Button

Summary	Use the RST function to reconfigure your island after you have added a new I/O
	module to a previously auto-configured island. If a new I/O module is added to the
	island, pressing the RST button forces the auto-configuration process. The updated
	island configuration data is automatically saved. RST works only after the island has
	been successfully configured at least once.
Physical
	The RST button is located immediately above the CFG port, and behind the same
Description	hinged cover:

RST button

Holding down the RST button for two seconds or longer causes the island to auto configure and the Flash memory to be overwritten.

Engaging the To engage the RST button, use a small screwdriver with a flat blade no wider than

RST Button 2.5 mm (.10 in). Do not use a sharp object that might damage the RST button or a soft item such as a pencil that might break off and jam the button.

When you push the RST button for at least two seconds, the NIM reconfigures the island bus as follows:

Stage Description

1The NIM auto-addresses the I/O modules on the island and derives their factory-default configuration values.

2The NIM overwrites the current configuration in Flash memory with configuration data that uses the factory-default values for the I/O modules.

3It re-initializes the island bus and brings it into operational mode.

Note: Network settings such as the fieldbus baud and the fieldbus node ID remain unaffected.
