1A00H Safety cycle
time exceeded
• Processing of the safety program,
from safety input to safety output,
did not complete within the safety
cycle time.
Continue • Check and correct the safety cycle
time.

occurrence
1A01H Safety cycle
processing error
• Safety cycle processing was not
executed because of either of the
following reasons:
(1) The safety cycle processing
takes too much time, and the
safety cycle time was exceeded.
(2) The safety cycle processing
interrupt was not executed in the
standard program due to an
instruction with excessively long
processing time.

1A40H Destination
station error in
safety
communications
• Error information has been
received from a safety
communication destination
station.
Continue ■SIL2 Process CPU
• Check the detailed information (safety
station system configuration
information) of the error by executing
module diagnostics using the
engineering tool and check "Station
No.", "Slot No. (another station)", and
"Base No. (another station)". If the
destination station is an intelligent
device station, execute the system
monitor for the remote head module in
the station and check the error details.
■Safety CPU
• Check the detailed information (system
configuration information) of the error
by executing module diagnostics using
the engineering tool and check the
displayed station number. If the
destination station is a remote device
station or remote I/O station, read error
history data of the destination station
by executing a command from the CC
IE Field Configuration window and
check the details of the error. If the
destination station is a master/local
station, execute the system monitor for
the station and check the details of the
error.
