Error Communication Error details and causes
code error code
302FH 25FEH When the slave function is used, the I/
O communication starts with the data
consistency setting of the master
function enabled.
3030H  The data consistency setting for
refresh and the data consistency
dedicated instruction setting for the
master function or slave function were
enabled simultaneously.
3036H 36FFH The value of the node address (MAC
ID) of the own node is out of range.
The value of the mode switch is out of
range.
303BH 3BnnH Two or more same node addresses
(MAC ID) are detected among the
parameters.
3084H 80FEH The receiving byte of the slave function
set with the parameter is out of range.
3085H 81FEH The transmit byte of the slave function
set with the parameter is out of range.
3086H 82FEH The number of the transmit bytes and
the number of the receiving bytes of
the slave function set with the
parameter are both set to 0.
30A0H A0FEH When both the master function and
slave function are used, the number of
their I/O points are set to 0.

3220H The parameter that is not supported is
written.

3C00H A hardware failure has been detected.

Action
Set the data consistency setting of the master function to
Disable in "Data Consistency Setting" of "Master/Slave
Function Common Parameters" under "Basic Setting".
Set "Data Consistency Setting" properly in "Master/Slave
Function Common Parameters" under "Basic Setting".
• Set the node address of the own node to 0 to 63 by the
node address setting switch.
• Set the mode switch within 0 to C.
• Set "Node Address" in "Slave Node Information" of
"Master Function Parameters" under "Basic Setting" so
that a node address does not overlap with all other
nodes.
• Set "Node Address" in "Slave Node Information" of
"Master Function Parameters" under "Basic Setting" so
that a node address does not overlap with the node
address of the own node.
Set "Slave Function Input Size" to 0 to 128 in "Slave
Function Parameters" under "Basic Setting".
Set "Slave Function Output Size" to 0 to 128 in "Slave
Function Parameters" under "Basic Setting".
Set "Slave Function Input Size" or "Slave Function Output
Size" to 1 byte or more in "Slave Function Parameters"
under "Basic Setting".
Take one of the following actions in "Basic Setting".
• Set one or more nodes in "Slave Node Information" of
"Master Function Parameters"
• Set "Slave Function Input Size" or "Slave Function
Output Size" to 1 byte or more in "Slave Function
Parameters".
• Check the parameter setting.
• Match the module set by the project of the engineering
tool to the version of the mounted module.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the error
occurs again even after taking the above, the possible
cause is a hardware failure of the module, base unit, or
extension cable. Please consult your local Mitsubishi
representative.
