Status Area and Troubleshooting
Section 9-2
Data Link Status: CIO 1500 + 25
×
(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.

Probable cause
Probable remedy
PLC’s CPU Unit error is 1:
ON
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.
The Unit is mounted to a
