HH
CPU Unit Fatal
Error
A fatal error occurred
in the CPU Unit.
•
If the Unit is the origina-
tor of the tag data link
connection, it stops
communications.
•
Communications will
continue for target con-
nection. If the Unit is
the target of the tag
data link connection
and the Controller sta-
tus is included in the
communications data,
the corresponding ele-
ment in the Target
Node PLC Error Flags
will change to TRUE.
•
The tag data link's send
data will be cleared to 0
in accordance with the
Output OFF settings,
and data transfer will
continue with that data.
0015
Eliminate the cause
of the error in the
CPU Unit.
The tag data link will
restart automatically
when the cause of
the error is elimi-
nated.
Errors Related to the Software Switches
---
---
C6
Multiple Switches
ON
Two or more soft-
ware switches were
ON simultaneously,
or a second software
switch was turned ON
before a prior opera-
tion was completed.
•
The error code will be
displayed on the 7-seg-
ment display for 30 sec-
onds.
•
The error display will be
cleared the next time
that a settings opera-
tion is completed nor-
mally. *_MultiSwOnErr
(Multiple Switches ON
Error) will change to
TRUE.
---
Execute software
switch operations one
at a time.
---

d5
Verification Error
(target non-exis-
tent)
The target registered
in the device parame-
ters does not exist.
The Unit will periodically
attempt to reconnect to
the target.
*_TDLOpnErr (Verifica-
tion Error), *_UnitErr (Unit
Error Occurred), and
*_NetErr (Network Error
Occurred) will change to
TRUE.
---
Check the following
items:
•
Is the registered
node’s power sup-
ply ON?
•
Is the cable con-
nected?
•
Is the cable dam-
aged or loose?
•
Is there excessive
noise?
