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.
