3.9.3 Node number selectors
You can use the node number selectors to assign a node number to the TJ1-
CORT. This node number identifies the TJ1-CORT in the CANopen network.
The upper node number selector sets the tens of the node number. The
lower node number selector sets the units of the node number. Both
selectors range from 0 to 9. To set a selector to n, turn the arrow to point to
the label n.
The CANopen node number can range from 0 to 127. But the TJ1-CORT
only supports node numbers from 1 to 99. The default node number, 0, is
invalid. Therefore, the default node number must be changed before the
TJ1-CORT is used.
