Error description
• Follow the procedure below.
(1) Check if each module is properly mounted on the base unit.
(2) Check if the operating environment of the Ethernet module
conforms to the general specifications of the CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the manual for
each module.
If the actions above do not solve the problem, please consult your
local Mitsubishi representative.
• Name the file with 255 characters or less.
• Check the operation of the connected device.
• Correct the response monitoring timer value.
• Check that Predefined protocol ready (X1D) has turned on before
executing the ECPRTCL instruction.
• Execute the ECPRTCL instruction after rewriting the protocol
setting data to the Ethernet module.
• If an error still occurs even after rewriting, replace the module.
• Correct the specified protocol number and execute the protocol
again.
• Register the corresponding protocol to the specified protocol
number.
• Correct the protocol setting data and register it again.
• Do not execute dedicated instructions which do not support
simultaneous execution.
• Correct the specified connection number and execute the
dedicated instruction again.
• Check the canceled protocol in the control data of the ECPRTCL
instruction (execution count result) and eliminate the cause of the
cancellation.
• Correct the specified protocol number and execute the protocol
again.
• Correct the number of protocols to be executed continuously and
execute the protocol again.
• Correct the specified connection number and execute the protocol
again.
• Correct the connection setting of the specified connection number
and execute the protocol again.
• Check if the cable is disconnected.
• Correct the connection setting of the specified connection number
and execute the protocol again.
• Check that there is no error in the connected device.
• Check that the sending from the connected device is not
interrupted.
• Check that there is no data lost due to a receive error.
• Check that there is no error in the data (packet) sent by the
connected device.
• Check the data sent by the connected device.
• To send data that exceeds 2046 bytes from the connected device,
divide the data into several parts and send them separately.
• Check the maximum allowable data length and specify the
maximum length or less in the data length storage area.
• Check the maximum allowable data quantity, and specify the
maximum quantity or less in the data quantity storage area.
