 (Unit No.) + 7 to + 22

When the first data link status word is set to the default (0000) for either the
manually set data link tables or automatically set data link tables (In the first
data link status word parameter), the data link status is stored in the above
area (CIO 1500 + 25 

× 

(Unit No.) (+ 7 to +22)).

When a different area has been set for the first data link status word, the sta-
tus is stored in the specified area. The status storage format is the same as
the one shown in the above diagram.

Note Refer to 5-4 Checking Data Link Status for details on status flags.

A fatal PLC error, non-fatal 
PLC error, or a watchdog 
timer error has occurred.

Refer to the PLC’s opera-
tion manual and correct 
the error. If the error occurs 
again, replace the PLC.
