3-12 Using Auto Start Mode

After 30-40 seconds, the adapter begins operations and uses the
configuration most recently applied. During the auto start mode
process, the Physical List Acquire Status field displays the words:
Auto Start Mode, but after the download is complete the field
displays the word: Idle.

Check for solid RED indicators on all modules

Verify that all non-backplane modules have the proper baudrate
(or have autobaud enabled)

Check that MAC IDs are set to proper values

Check scanlist

browse to Subnet and view scanlist, or look at mapping text

Make sure the scanlist was saved (if not, why?)

check ‘maximum backplane mac/id’ parameter. It should
equal the number of modules residing on the backplane.

After ASM has completed (i.e., Physical List Acquire Status field
is Idle), verify that the operation was successful and that each
I/O module was added to the adapter’s scanlist. The PointBus
LED (1734-ADN) or Subnet Led (1734-ADNX) should be solid
green. This indicates only that the adapter is able to establish
I/O connections with each module in its scanlist, not that each
module on the Subnet was successfully added to its scanlist.

To verify the presence of each module in the adapter’s scanlist,
one of the following checks should be done:

• Each I/O module’s Network or Module/Network LED should

be solid green. If the device has neither LED, use one of the
following methods.

• By browsing to the Subnet and uploading the adapter’s

scanlist using RSNetWorx for DeviceNet and verifying that the
device is found in the scanlist.

• By repeatedly uploading the EDS parameter “Cycling I/O

Mapping” to verify that a mapping for the concerned module
exists. See page 2-15 for more information about this
parameter.

If one of the following is observed, it is likely that one of the
Subnet modules has been addressed incorrectly or is configured
to communicate at the wrong baud rate.

• The adapter’s PointBus LED (1734-ADN) or Subnet LED

(1734-ADNX) is solid or blinking red
