Note
Note The C200Hj PCs include the C200HX, C200HG, C200HE, and C200HS.
Each of the above sets of four bits contains the four flags indicating data link sta-
tus for a node, as shown below.
This example illustrates the location of data link status flags for a 10-node data
link with the following parameters. These are the only words that will be used.
The following memory areas can be used to store the status data. Be sure to
allow enough words after the beginning status word so that the entire link status
area fits within the same data area.
Data link servicing is given priority in SYSMAC LINK Systems. The communica-
tions time for a data link can thus be maintained as a constant, regardless of
whether or not SEND(90)/RECV(98) are used. Fixing the data link communica-
tions time at a constant value fixes the data link I/O response time as well.

Turned ON to indicate the PC is in RUN or
MONITOR mode. OFF indicates
PROGRAM mode.
Turned ON to indicate the PC has stopped
because of a fatal error.
Turned ON to indicate that there is a
communications error (time out), that the
Unit is not part of the System, or that the
data link is not active.
Turned ON to indicate the node is part of
the data link. OFF indicates that the data
link tables of the start-up node do not
match, or no operation is possible because
the data link table has not been created.
