4.
Apply power to the linking device and DeviceNet network.
TIP
Two 120 ohm termination resistors (supplied with the linking device) may be
required for proper network termination at each end of the trunk line. See the
DeviceNet Specification (available from the Open DeviceNet Vendors
Association at
) for specific rules on DeviceNet
connections and termination.
IMPORTANT
The linking device defaults to Autobaud. This means that the linking device
automatically finds the network communication rate at when power is
applied. You must specify a master device, such as a DeviceNet Bridge Module
(catalog number 1756-DNB) so that the linking device can pick up the correct
communication rate. If you do not have another device installed, you must
use RSNetWorx for DeviceNet software to set the communication rate, as
described in
Set the DeviceNet MAC ID and Communication Rate on page 21
.
Do not attempt to commission the linking device on a network configured at
a different communication rate.
