Error Codes Related To Safety Communication - Mitsubishi Electric NZ2GFSS2 32D S1 User Manual

Error codes related to safety communication

The following table lists safety communication error codes.
The ERR LED does not turn on when a communication error related to the safety communication occurs, the same as a case
when a communication error of the CC-Link IE Field Network occurs. When an error occurs, the SAFETY LED turns off and
the D LINK LED does not change.

Error name Description
and cause
Safety An error was
communication detected in the
error safety
communication
with the master
station.
Safety A communication
communication interrupt has
disabled due to a occurred on CC-
communication Link IE Field
interrupt Network and the
safety
communication is
stopped.
Action
• Refer to the following and set
module parameters and perform
the safety module validation
according to the parameter
setting procedure. ( Page 68
VARIOUS SETTINGS)
• Correct the number of points in
the "RWw/RWr Setting" in the
"Network Configuration Settings"
of the master station.
• Check the firmware version of
the CPU module and the master
module. ( Page 46
Applicable products)
• Correct "Safety Communication
Setting" of the master station
again.
• When the parameter setting has
no errors, there may be an
influence from noise or a
hardware failure. If the same
error occurs again even after
measures have been taken
against noise, the module may
be in failure. Please consult your
local Mitsubishi representative.
• Check the network status using
the CC-Link IE Field Network
diagnostics of the engineering
tool for errors.
• When no error has occurred on
the network, there may be an
influence from noise or a
hardware failure. If the same
error occurs again even after
measures have been taken
against noise, the module may
be in failure. Please consult your
local Mitsubishi representative.
