Error Codes Related To Safety Communication - Mitsubishi Electric MELSEC iQ-R Series 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 CC-Link IE Field Network occurs. When an error occurs, the SAFETY LED turns off and the D
LINK LED does not change.

Description and cause
Safety An error was detected in the
communication safety communication with the
error master station.
Safety A communication interrupt has
communication occurred on CC-Link IE Field
disabled due to a Network and the safety
communication 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 67 Module parameter setting procedure
• 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.
• Correct "Transmission interval monitoring time" of the module
parameter as well as "Safety Communication Setting" of the
master station. After that, refer to the following and set module
parameters and perform the safety module validation according
to the parameter setting procedure.
