Setting Data Links Section 5-2

CS/CJ-series Startup Node

Automatic setting for the CS/CJ Series can be performed using either equality layout (previous method), where each node is allocated the same link area size, or 1:N allocations, which allows individually set exchange of data between the master node and slave nodes. There are 3 types of 1:N alloca- tions, which use different allocation methods.

Features of Equality Layout:

•The send areas for each node are of the same size.

•Area 1 can be selected from bit-access areas (i.e., CIO and LR Areas) and area 2 can be selected from DM Area.

•Data link area allocation is performed in ascending order of node address.

•Each node can be specified to either participate or not participate in the data links.

•The data link areas are the same for all nodes participating in the data links.
