Description Action
• Check whether or not the specified MAC ID, class ID,
instance ID and attribute ID are correct.
• Referring to the slave node manual, check the
condition under which the slave node notifies this
error, and take an appropriate action.
• Check the entire network and slave node states for
any fault such as slave node failure, or disconnection
of a terminating resistor.
• Check whether or not the specified MAC ID, class ID,
instance ID and attribute ID are correct.
• In the case of set attribute, verify that the specified
data is sufficient and the data length is correct.
• Referring to the slave node manual, check the
condition under which the slave node notifies this
error, and take an appropriate action.
• Check whether or not the specified MAC ID, class ID,
instance ID and attribute ID are correct.
• Referring to the slave node manual, check the
condition under which the slave node notifies this
error, and take an appropriate action.
• Reduce the data returned from the slave node to 240
bytes or less.
• Check whether or not the specified MAC ID, class ID,
instance ID and attribute ID are correct.
• Referring to the slave node manual, check the
condition under which the slave node notifies this
error, and take an appropriate action.
• Check the entire network and slave node states for
any fault such as disconnection of a terminating
resistor.
• Specify a node No. in the range of 0 to 63.
• Check the entire network and slave node states for
any fault such as disconnection of a terminating
resistor.

command No.
• Set Y11 to on to set the own node online.
• Perform a hardware test to check for hardware failure.
• Check the entire network and slave node states for
any fault such as disconnection of a terminating
resistor.
• Check the entire network and slave node states for
any fault such as disconnection of a terminating
resistor.
• Set a node No. that is not being used for a reserved
