Operation Description and steps to take
status
Stops An interrupt occurred without an interrupt request.
A hardware problem or error due to noise is possible.
Turn off the power and check the noise conditions.
Stops An interrupt occurred without an interrupt request.
A hardware problem or error due to noise is possible.
Turn off the power and check the noise conditions.
There is no interrupt program for an interrupt which occurred.
Check the number of the interrupt program and change it to
agree with the interrupt request.
CPU2 stops This error occurs when a FP3/FP10SH is used as CPU2 for a
multi-CPU system.
Please contact your dealer.
Stops An abnormal unit is installed.
Check the contents of special data register DT9036/DT90036
and locate the abnormal unit. Then turn off the power and
replace the unit with a new one.
Stops A unit, which cannot be installed on the slave station of the
MEWNET-F link system, is installed on the slave station.
Remove the illegal unit from the slave station.
Stops The number of slots or I/O points used for MEWNET-F exceeds
the limitation.
Re-configure the system so that the number of slots and I/O
points is within the specified range.
Stops I/O overlap or I/O setting that is over the range is detected in
the allocated I/O and MEWNET-F I/O map.
Re-configure the I/O map correctly.
Stops I/O mapping for remote I/O terminal boards, remote I/O terminal
units and I/O link unit is not correct.
Re-configure the I/O map for slave stations according to the I/O
points of the slave stations.
Stops When reading in the program from the IC memory card (due to
automatic reading because of the dip switch 3 setting or
program switching due to F14 (PGRD) instruction ):
 IC memory card is not installed.
 There is no program file or it is damaged.
 Writing is disabled.
 There is an abnormality in the AUTOEXEC.SPG file.
 Program size stored on the card is larger than the
capacity of the CPU.
Install an IC memory card that has the program properly
recorded and execute the read once again.
