Cause and
correction
Assumed cause Correction Prevention
Power was interrupted when a down-
load was in progress for the TCP/IP
advanced settings.
Cycle the power supply to the Con-
troller or reset the Controller. If normal
operation is restored by cycling the
power supply to the Controller or
resetting the Controller, a memory
error has occurred and may occur
again. Replace the CPU Unit. If oper-
ation is not restored even after you
cycle the power supply or reset the
Controller, perform either of the fol-
lowing operations and download the
settings again.
• Memory All Clear operation.
• Identify the cause of error from
those listed in the event log details
and correct the settings.
If operation is not recovered by the
above, replace the CPU Unit.
Do not turn OFF the power supply to
the Controller while a download is in
progress for the TCP/IP advanced
settings.
Memory error None
There is a mistake in the IP router
table settings or hosts settings.
Correct the IP router table settings or
hosts settings.
Check that there are no mistakes in
the IP router table settings or hosts
settings.
