Automatic Generation of Data Link Tables
Item
Basic specifications for data links are provided in the following table.
When both a SYSMAC LINK System data link and a SYSMAC NET Link System
data link exist between two PCs, the words that are linked and the data link sta-
tus area must not overlap; each System must have unique link words and status
areas.
When a SYSMAC LINK Unit and a PC Link Unit are mounted on the same PC, do
not use the LR area for a SYSMAC LINK System data link or data link status
area.
AR 0700 through AR 0703 and AR 0704 through AR 0707 are used to specify
both automatic generation and data link table structure, as shown below. The
status of these bits is effective only in the PC at the start-up node.
The data in the first table is used to designate whether word allocation will be
automatic (according to these AR bits) or whether it will be set manually (from a
SSS/CVSS), and to designate which areas will be linked. The data in the second
table is used to designate the number of words per node. If manual generation
(the first setting in the first table) is used, the settings in the second table are
ignored.
These settings are read every cycle while the SYSMAC LINK System is in
operation.

LR area: 64 words max. (128 bytes)
DM area: 254 words max. (508 bytes)
2,966 words total in the LR and DM areas
(918 words total when only C200HW-SLK13/23 Units are being used.)
Settings in AR 07 determine whether LR 00 to LR 63 and/or DM 0000 to
DM 0127 will be used as data link areas, and whether these areas will be
divided equally among 2, 4, 8 or 16 nodes.
Set from the SSS/CVSS.
