What is the 1734-ADN(X) Adapter? 2-9

Connections

Your adapter supports the following connections on both the primary

DeviceNet network and Subnet:

• I/O connections:

– Polled

– Strobe

– Cyclic

– COS

• Explicit connections

You can use I/O mapping to determine the data contained in each

connection.

The adapter supports Master/Slave connection types on the

DeviceNet network. On the Subnet, the adapter functions as a

scanner device, exchanging data with I/O modules.

Baudrates

Choose baudrates for the adapter in the RSNetWorx for DeviceNet

software. It supports these rates:

• 125Kbaud

• 250Kbaud

• 500Kbaud

• Autobaud - The adapter detects the primary DeviceNet network

baudrate and automatically sets its own baudrate to match

the network.

• For the 1734-ADN, the PointBus can be configured to operate at

1Mbaud (1000Kbaud).

Auto Start Mode

Auto Start Mode lets you easily get your adapter installed and

operating. In this mode, the adapter’s configurable features operate as

they were most recently configured. For example, if Autobaud on

DeviceNet was enabled in the adapter’s last configuration, it will be

enabled when Auto Start Mode is used.

For a more detailed explanation of how to use Auto Start Mode, see

Chapter 3.
