3-5-1 SYSMAC LINK System Data Link Settings
AR 0700 to AR 0703 and AR 0704 to AR 0707 are used to designate word
allocations for operating levels 0 and 1 of the SYSMAC LINK System. Alloca-
tion can be set to occur either according to settings from a Peripheral Device
(e.g., FIT) or automatically in the LR and/or DM areas. If automatic allocation
is designated, the number of words to be allocated to each node is also des-
ignated. These settings are shown below.
