address selected is not the same as the one saved previously and the

Off and then back On.
NOTE:
If the “
Display address setting:__
" fi eld is set to
0
, the terminal will communicate with the controller
(I/O board) using point-to-point protocol (not pLAN). The display fi eld “
I/O Board address:__
” will disappear as it has
no meaning until you set the controller (I/O board) pLAN address.

Press the ( ) key to set the pLAN address (#1 – 8) for the controller
(I/O Board). The pLAN address #1 is already assigned by default to the
fi rst (Lead) controller in the group. Address #2 is to be assigned to the
fi rst controller added to the group (address #3 is to be assigned to the
second controller added and so on). Then press the (

your selection. A message “
NO LINK
” will appear.
Next , press the Up ( ), Down
( ) and Enter (
) keys simultaneously. Reconfi gure the terminal address following the steps
in Section 4.6.2 again. This time set the terminal address to match the corresponding controller (I/O board) address.. If the
controller is assigned address 2, then the corresponding terminal address should be set to 31 as shown in the table on the
preceding page. If the next controller is assigned address 3, the corresponding terminal should be set to 30.
After setting the correct terminal address, press the (
) key once to confi rm your selection. A message “
NO LINK

appear. At this point, the terminal has been set with the correct address for the controller and the controller has been set
for the terminal, but now they need to be assigned to each other.
