Setting Data Links

Section 5-2

Words N+22 through N+25 register nodes that will participate in the data
links. The numbers in the table are the node addresses. The bit status given
for each node address indicates whether the node is to participate in the data
links.

Participate: ON
Not participate: OFF

Note

1.

Leave the reserved words set to 0 (N+18 to N+20).

2.

When using automatic data link creation with 1:N allocations, set DM Pa-
rameter Area words N+2 to N+11 (which were previously used for automat-
ic setting with equality layout) to 0.
