What Is the ArmorPoint DeviceNet Adapter? 2-9
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. The adapter 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 1738-ADN12, -ADN18, and -ADN18P, the PointBus can
be configured to operate at 1Mbaud (1000Kbaud).
• For the 1738-ADNX, the Subnet can be configured to operate at
125K, 250K, and 500K baud only.
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
