receipt data
error
• The received data is abnormal. 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.
• The possible cause is a hardware
failure of the module performing safety
communications. Please consult your
local Mitsubishi representative.
■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.
• The possible cause is a hardware
failure of the module performing safety
communications. Please consult your
local Mitsubishi representative.

communications
• Safety communications with a
destination station could not be
resumed within a safety I/O hold
time.
Continue • Check and correct the safety I/O hold
time.
• The possible cause is malfunction due
to noise or cable failure. Check that
there is no error in a transmission path
by executing CC-Link IE Field
diagnostics. Check the distance of
wires and cables and the grounding
status of each device as well.
• 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

mismatch
• The CC-Link IE Field Network
configuration differs between the
systems A and B. (The error is
detected in the standby system.)
Continue • Check that all network cables are
connected correctly.
• Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible cause is
a hardware failure of the network
cable. Please consult your local
Mitsubishi representative.
