Configure Scanner Mode Chapter 2
The icons on the 56RioCfgScan tool show the partial rack sizes and locations.
Racks are shown with starting and ending I/O groups. For example, the
following tree shows rack 0 consisting of 4 quarter racks.
Block transfer modules must be added and configured manually.
When the module is in scanner mode, the 1756-RIO module performs the
following actions during autoconfigure. The module:
• detects the network baud rate by sending messages at each baud rate,
looking for responses.
• then sends messages to all possible racks on the network.
• builds a network configuration from the observed network responses.
• displays the network configuration.
Partial Rack (1/4 rack)
Rack 0
IMPORTANT
The controller with the connection to the 1756-RIO module
must be in program mode when you perform an
autoconfiguration. The following error message displays if the
controller is not in program mode.
