Action
• Correct the descriptions of the control data.
• Set the open settings parameters. Or, execute the OPEN
instruction through control data.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data
after a certain period of time.
• Check if the connection cable is disconnected.
• Check that there is no connection failure with the switching hub.
• Execute the communication status test, and if the test was
completed with an error, take the corrective action.
• Execute the module communication test, and check that there is no
failure in the module.
• Correct the descriptions of the control data.
• Set the open settings parameters. Or, execute the OPEN
instruction through control data.
Correct the channel to a value within the allowable range of each
dedicated instruction.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data
after a certain period of time.
• Check if the connection cable is disconnected.
• Check that there is no connection failure with the switching hub.
• Execute the communication status test, and if the test was
completed with an error, take the corrective action.
• Execute the module communication test, and check that there is no
failure in the module.
Check and correct the response waiting time.
Correct the number of resends.
Correct the specified data length.
Correct the specified port number.
• Do not perform the open processing to an already opened
connection.
• When communications with the external device cannot be
performed, perform the close processing before the open
processing.
After completion of the open processing, perform the communication.
• Change the channel number.
• Execute again after the send or receive instruction is completed.
Set the arrival monitoring time to a value within the allowable range.
Execute the dedicated instruction after the initial processing is
completed.
• Execute again after correcting the execution/abnormal end type in
the control data.
• If the problem cannot be resolved with the above actions, the
possible cause is a hardware failure of the module. Please consult
your local Mitsubishi representative.
• Execute again after correcting the request data to be within the
range.
• If the error occurs again even after taking the above, please
consult your local Mitsubishi representative.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data
after a certain period of time.
• Check if the connection cable is disconnected.
• Check that there is no connection failure with the switching hub.
• Execute the communication status test, and if the test was
completed with an error, take the corrective action.
• Execute the module communication test, and check that there is no
failure in the module.
• Execute again after correcting the requested module I/O No. at the
request source of the dedicated instruction.
• If the error occurs again even after taking the above, please
consult your local Mitsubishi representative.
