Description and steps to take
Probably a hardware problem. Please contact your
dealer.
The number of installed units exceeds the limit.
Turn off the power supply and check the re-
strictions on unit combinations.
Probably an error in the system registers. Check
the system register settings.
Probably a hardware problem. Please contact your
dealer.
An interrupt occurred without an interrupt re-
quest. A hardware problem or error due to noise
is possible. Turn off the power and check the
noise conditions.
An interrupt occurred without an interrupt re-
quest. 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 inter-
rupt program and change it to agree with the
interrupt request.
A faulty unit is installed. Replace the unit with a
new one.
The connection condition of an I/O unit has
changed compared to that at the time of pow-
er-up. Check the error using
sys_wVerifyErrorUnit_0_15 and locate the faulty
I/O unit. Set the operation status using system
register 23 to continue operation.
Operation has become impossible after a
high-level instruction was executed and a calcula-
tion error occurred. The causes of operation er-
rors vary depending on the instruction. Set the
operation status using system register 23 to con-
tinue operation.
The self-diagnostic error specified by the
F148_ERR instruction has occurred. Use Monitor
 PLC status or to check the error code.
