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.
Automatic Setting, Equality Layout
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.
