Set the Node Address
Valid node addresses are 00 to 63.
Set the node address using the rotary switches or a DeviceNet software
configuration tool like RSNetWorx for DeviceNet
TM
. Setting the switches
between 64 and 99 allows the software to have address control.
Each board is shipped with the node address set to 63 in the board’s
memory. The rotary switches are set for position 99 at shipment. The
switches are located near the center of the board. The two switches are:
•
MSD (most significant digit)
•
LSD (least significant digit)
To reset the node address, use a small blade screwdriver to rotate the
switches. Line up the small arrow on the switch with the number setting
you wish to use.
The rotary switches are read at board power up only. Settings between 64
and 99 cause the board to use the last valid node address stored in the
board’s memory. Example: The last setting was 40. If a change is made to
68, and then you power up, the address will default to 40.
The board is equipped with AutoBaud detect. AutoBaud lets the board
detect the baud rate on your DeviceNet network and automatically adjusts
to that rate. The board is shipped with AutoBaud enabled.
