3.2.2 Rotary switches for node address setting
The DN611 has rotary switches on the bottom for node address setting (0 to 63 in
decimals) (Figure 3-3). NA-H is used for setting a figure in the digit of tens and NA-L, a
figure in the digit of ones.
Since both NA-H and NA-L can set a value from 0 to 9, it is technically possible to set 0
to 99. If a value anywhere from 64 to 99 is set, however, the DN611 will develop a node
address setting error. To reset it, either issue a reset request or switch power back on
after setting a node address correctly.
A DeviceNet network requires that each of the nodes connected to it has a node
address unique to it. If a DN611 node address is the same as that of another node, the
DN611 develops a "same node address detected" error when it goes into run mode. To
reset the error, allocate the correct node address and, issue a reset request or switch
power back on.
NA-H NA-L Default: 0

Caution
1. Make sure not to change a node address while the S controller power is on. Otherwise, a
node address setting error will occur. To reset, either issue a reset request or turn power
back on again after correctly setting the DIP switches.
