Data Link Status Section 4-9
4-9-2 Word Structure
The following table shows the data link status in memory. The numbers within
the table are in order of the nodes are set in the data link table (refresh param-
eters). These will correspond to the node addresses when using automatic
settings.
The data link status area corresponds to the first word of the words allocated
to the SYSMAC LINK Unit as a CPU Bus Unit +8 to +23.
Word: CIO 1500 + (25 x unit number) +8 to +23.
The status of the bits allocated to each node is as follows:
Bit 00, 04, 08, or 12:
CPU Unit Operating Flag
Bit 01, 05, 09, or 13: CPU Unit Error Flag
Bit 02, 06, 10, or 14: Data Link Communications Error Flag
Bit 03, 07, 11, or 15: Data Link Active Flag
The actual words allocated to each node address for data link status are
shown in the following table.
If the Local Node Data Link Active Flag (bit 15 of first word +23) is OFF, the
data link status will be maintained as it was immediately before operation
stopped. This may not be the same as the actual current status. When using
