Install the Board
To install the board:
•
set the node address.
•
mount the board (brackets, mounting plate, plastic cover).
•
connect the board (DeviceNet network, I/O).
•
communicate with your board.
•
configure the parameters.
More detailed information about each of these steps is in the following procedures.
Set the Node Address
Valid node addresses are 00...63.
Set the node address by using the rotary switches or a DeviceNet configuration tool
such as RSNetWorx for DeviceNet software. 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 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 only when you apply power to the board. Settings
between 64 and 99 cause the board to use the last valid node address stored in the
board’s memory.
