8B
An interrupt subroutine
longer than 10 ms was
executed during I/O
refreshing of a Remote I/O
Unit or during Host Link
servicing.
An attempt was made to
execute a different type of
I/O refresh from the type set
for the Special I/O Unit
cycle refresh.
9A An error occurred in data
transfer between a
High-density I/O Unit and
the CPU Unit.
9B An error has been detected
in the PC Setup. This error
will be generated when the
setting is read or used for
the first time.
9C An error has occurred with a
Communications Board.
9D An error has occurred
during data transmission
between UM and a Memory
Cassette because:
Not in PROGRAM Mode.
UM or Memory Cassette is
read-only.
Insufficient capacity in UM
or Memory Cassette.
A checksum error occurred
in the Memory Cassette
F8 Watchdog timer has
exceeded 100 ms.
E7 Unit has been removed or
replaced by a different kind
of Unit, making I/O table
incorrect.
B0 or B1 Error occurred in
transmissions between
*
Remote I/O Units.
Probable cause
Check the contents of
SR 262 and SR 263 and
verify that the interrupt
subroutine's processing
time is less than 10 ms.
Change the program or the
Special I/O Unit cycle
refresh setting so that the
same refresh method is
used.
Check AR 0205 to AR 0214
to identify the Unit with a
problem, replace the Unit,
and restart the PC.
Check and correct the PC
Setup settings.
(SR 27500 to SR 27502
indicate which part of the
PC Setup is incorrect.)
Refer to the
Communications Board's
Operation Manual for
details.
Make sure that the PC is in
PROGRAM mode.
Make sure that the Memory
Cassette is not
write-protected.
Make sure that the UM and
Memory Cassette capacity
is sufficient.
Make sure that SYSMAC
NET data links are not
active during the transfer.
Transfer the data again.
Program cycle time is
longer than recommended.
Reduce cycle time if
possible.
Use I/O Table Verify
Operation to check I/O table
and either connect dummy
Units or register the I/O
table again.
Check transmission line
between PC and Master
and between Remote I/O
Units.
