The link consists of two similarly structured sub-lists, each with 16 data
words. For each of the four sender CPUs (S1, S2, S3, S4) three entries are
required to describe a link.
•• Number of data fields
The number of data fields specifies the size (= the number of data
words) of the data word area to be transferred. (If links do not exist
or you do not require them, enter 0 for the number of data fields,
and for the DB type and DB number.)
•• DB type
Type of data block containing the data word area to be transferred.
•• DB number
Number of the data block containing the data word area to be trans-
ferred.
As shown in the table, these entries can be read in and completed in lines.
If, for example, you want to transfer the first two data fields in data block
DB 10 from CPU 2 (S2) to CPU 3, make the following entries:
CPU 2 (S 2) sends ..
Sub-list 2 is identical to the assignment ("manual" mode) required for
the INITIALIZE function (OB 200). Within the data block, sub-list 2
must occupy data words 0 to 15 and sub-list 2 data words 16 to 31.
You must not alter the entries shown in bold face.
