Setting Data Links Section 5-2

•Each slave nodes receives data from the previous node and then sends data to the next node. Data is thus passed in ascending order of the nodes participating in the data link.

•One area is selected from the bit-access areas (e.g., CIO Area) or word- access areas (e.g., DM Area).

•Data link areas are allocated in ascending order of node addresses.

•Data link participation can be specified for each node.

When bits 6, 5 and 4 are set to 1, 0 and 1 respectively, automatic setting with 1:N allocation is specified.

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. Set 0 as the values of the reserved areas (N+17 to N+20).

2.When using automatic data link creation with 1:N allocation, set DM Pa- rameter Areas N+2 to N+11 (which were previously used for automatic set- ting with equality layout) to 0.

Setting Range for Automatic Creation with 1:N Allocation, Chain Type

Item	Setting range
Data link mode	Specify automatic data link creation with 1:N allocations.
1:N allocation	Specify Chain Type.
