Data Link Specifications Section 4-2
Table Generation Data link tables can be generated automatically or manually. Data link tables
generated automatically are identical in all PLCs in the data link, with the
words of the data areas listed below divided equally among 2, 4, 8, or 16
nodes. The number of words allocated to each node depend on the number of
nodes linked and is given in
4-2-1 Specifications Table later in this section.
Manual generation provides much greater flexibility in making data links
among PLCs, but require that you manually input the data link tables. Manu-
ally generated data links can contain far more words and can use any part of
the CIO Area and/or DM Area, as shown in the following table.
Note Use Ver. 1.2 Service Pack 1 of the CX-Programmer. Settings for CS-series
SYSMAC LINK Units cannot be made with earlier versions of the CX-Pro-
grammer.
Controlling Data Links Data links can be activated and deactivated by turning ON and OFF bit 00 of
the first CPU Bus Link Area word allocated to the SYSMAC LINK Unit in PLC
memory, i.e., bit 00 of word (100 x unit number).
