Node number selectors
You can use the node number selectors to assign a node number
to the TJ1-PRT. This node number identifies the TJ1-PRT in the
PROFIBUS 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
. Refer to the chapter, Communication
Protocols in the Programming Manual.
