Using Auto Start Mode
3-13
•
An I/O module’s Network or Module/Network LED is solid
red
•
It appears that the adapter has not saved a scanlist
Use the following procedures to attempt to remedy the problem:
•
Verify that each non-backplane module’s address and
baudrate have been set correctly.
•
Verify that each backplane module is configured to autobaud.
The adapter’s EDS parameter “Set Backplane Autobaud’ can
be used to set each module’s autobaud parameter. It is
necessary to cycle a module’s power before the autobaud
parameter change takes effect. In rare situations, it may be
necessary to download the parameter and cycle power
several times before each backplane module’s autobaud
parameter has been changed.
Note that if the adapter is configured to autobaud on the
primary DeviceNet network, network traffic on the primary
network is required before the backplane modules will attempt
to communicate. For this reason, it is sometimes helpful to have
RSLinx continuously browsing the primary network while
attempting the ASM process and verification.
When it is believed that each non-backplane module is correctly
configured and that each backplane module is able to
communicate on the Subnet, the ASM process can be attempted
again.
After successfully configuring your adapter with the Auto Start Mode
feature, the adapter must still be added to the primary DeviceNet
network scanner’s scanlist. See Chapter 5 for more information.
Using Custom Configuration
The Auto Start Mode is recommended to quickly and easily get your
POINT I/O system ‘up and running’. But this mode does not prevent
you from changing the adapter’s default configuration after system
operation has begun.
For more information on how to write custom configuration for your
adapter on DeviceNet, see Chapter 4, Configuring the 1734-ADN(X)
Adapter’s SubNet and Chapter 5, Adding the 1734-ADN(X) to the
DeviceNet Scanner’s Scanlist.
IMPORTANT
Running Auto Start Mode causes the adapter’s ADR
configuration for the Subnet modules to be reset.
