SYSMAC LINK/SYSMAC NET Link Data link status is output to SR 238
through SR 241 for the operating level 0 data link, and to SR 242 through SR
245 for the operating level 1 data link in the SYSMAC NET Link or SYSMAC
LINK System.
The meaning of each bit in these areas differs depending on whether the
data link is in a SYSMAC LINK System or SYSMAC NET Link System, as
shown below.

PC Link Systems
When the PC belongs to a PC Link System, words 247 through 250 are used
to monitor the operating status of all PC Link Units connected to the PC Link
System. This includes a maximum of 32 PC Link Units. If the PC is in a Multi-
level PC Link System, half of the PC Link Units will be in a PC Link Subsys-
