areas
In the following example, the send data from node 1 is split into three parts and
each part is received by a different node, i.e., each of the other nodes receives
only part of the send data from node 1. This enables effective use of data link
memory areas without wasting space. In this way, a type of message service
(i.e., specific data to a specific node) can be achieved through data links.
# 1
Optical Ring System: 62 nodes max. (2 nodes min.)
Wired System: 32 nodes max. (2 nodes min.)
Number of send/receive words per node (total of area 1 and area 2) :
CS1:
C200HX/HG/HE, CV:
Computer: Manual setting
Number of send words per node
(total of area 1 and area 2): Up to 1,000
Manual Area 1, 2: Bit area (IR, CIO, and LR Areas)
setting
However, area 1 and area 2 cannot be set in the same memory area.
Automatic Area 1: IR, CIO, or LR Area
setting
Area 2: Data Memory (DM and EM Areas)
Note When optical and optical ring connections are combined, the maximum number
of nodes is 32 and the maximum number of data link words for a computer for
manual settings is 32,000 words.
