Setting the Node Address
The value of DN Addr Cfg (2) determines the node address if all of
the module DIP switches are in the CLOSED position (all 0s). We
recommend that you do not use node address 63 because all new
devices use it as the default address. Address 63 is also used for
Automatic Device Recovery.
Step 1. Set the value of DN Addr Cfg (3) to a unique node address.
See figure 4.6.
Step 2. Reset the module. Refer to section 4.9, Resetting the
Module, for this procedure.
If you are using RSNetWorx for DeviceNet, select Network >
Single Browse Path to see the new address; then delete the old
address.
4.5
Setting the Data Rate
The value of DN Rate Cfg (4) determines the DeviceNet data rate if
all of the module DIP switches are in the CLOSED position (all 0s).
The Autobaud setting will detect the data rate used on the network if
another device is setting the data rate. Your application may require
a different setting.
Step 1. Set the value of DN Rate Cfg (4) to the data rate at which
your network is operating.
Step 2. Reset the module. Refer to section 4.9 for this procedure.
