When manual setting is used,
there is an error in the data link
table.
When automatic setting is
used, the data link parameters
at the startup node are incor-
rect for the local node (the
data link area is out of range
for the local node.)
Automatic setting is used with
1:N allocations, but the device
does not support this function.
When manual setting is used,
there are no data link tables
set for the local node.
When automatic setting is
used, the startup node is not
set to participate in the data
links.

Refer to 5-2-2 Manual Setting
and remake the data link table.
Refer to 5-2-4 Automatic Set-
ting, reset the parameters for
the startup node DM Area so
that the local node can partici-
pate in the data link, and then
restart the data link.
Use a Controller Link Unit that
supports automatic data link
creation with 1:N allocations.
Refer to Automatic Setting on
page 131 for details.
Set data link tables for the
local node.
Stop the data links, remake
and set the parameters in the
startup node’s DM Area, and
then restart the data link.
