Description Corrective action
• Check that the specified MAC ID, class ID, instance ID and
attribute ID are correct.
• In case of attribute write, 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 that 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.
• Set the data to be returned by the slave node to 240 bytes or
less.
• Check that 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 statuses such as
whether or not a terminal resistor is disconnected.
• Specify a slave node number between 0 and 63.
• Check the entire network and slave node statuses such as
whether or not a terminal resistor is disconnected.
• Set the data length to 240 bytes or less.
• Set a command number to either
0001 , 0101 , 0102 , 0201 or FE∗∗

• Turn ON Y11 to set the local node online.
• Execute a hardware test to verify whether or not hardware is
normal.
• Check the entire network and slave node statuses such as
whether or not a terminal resistor is disconnected.
• Check the entire network and slave node statuses such as
whether or not a terminal resistor is disconnected.
• Set a node number that is not being used for a reserved node.
