14-4        Using FLEX™ I/O Modules on a DeviceNet Network

To set the address of the Flex I/O adapter 1794-ADN: 

Before you make an online change to a Flex I/O adapter that effects 
the size of its input or output data, remove the adapter from the scan 
list of the scanner. Otherwise, RSNetWorx software responds with the 
following error: Device state conflict.

For example, adding or removing an I/O module to/from the adapter 
changes the I/O data of the adapter. To add or remove a module:

1. Remove the adapter from the scan list of the scanner.

2. Add or remove the I/O module to/from the adapter and 

reconfigure the adapter.

3. Add the adapter back into the scan list.

Typically, changes that do not effect the I/O size are permitted while 
the adapter is still in the scan list. 

1. To change the address, press the button above or below a number.
2. Connect the adapter to the network.
3. Turn on power to the adapter.
4. Check the Mode/Net STATUS light.

When autobaud is on, the device waits until it hears another device 
on the network. It then sets its baud rate to that of the other device.
