4.5 List of Error Codes
Action
• Check the operating status and connection status of the target device.
• Check the connection of the Ethernet cable and switching hub.
• Check the line status of Ethernet.
• Reset the CPU module and target device, and retry the operation.
If the above actions do not solve the problem, contact the manufacturer of
the target device.
• Check the operating status and connection status of the target device.
• Check the connection of the Ethernet cable and switching hub.
• Check the line status of Ethernet.
• Reset the CPU module and target device, and retry the operation.
If the above actions do not solve the problem, contact the manufacturer of
the target device.
• Check the operating status and connection status of the target device.
• Check the connection of the Ethernet cable and switching hub.
• Check the line status of Ethernet.
• Reset the CPU module and target device, and retry the operation.
If the above actions do not solve the problem, contact the manufacturer of
the target device.
• Check the operating status of the external device.
• Check if there is any error in the line status.
If the above actions do not solve the problem, contact the manufacturer of
the target device.
• Check the operating status and connection status of the target device.
• Check the connection of the Ethernet cable and switching hub.
• Check the line status of Ethernet.
• Reset the CPU module and target device, and retry the operation.
If the above actions do not solve the problem, contact the manufacturer of
the target device.
Switch the operating status of the CPU module to the STOP state (excluding
a stop error), and enable the remote device test function.
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Correct the target station No. of transient data, and retry the operation.
• When the access destination is a module with a different network No.,
check if "Routing Setting" of "CPU Parameter" is correctly set.
Execute the instruction again after correcting the read data or write address
at the transient request source.
Execute the instruction again after correcting the target station No. at the
transient request source.
Execute the instruction again after correcting the target station No. at the
transient request source.
Execute the instruction again after correcting the target station No. at the
transient request source.
Execute the instruction again after correcting the target station No. at the
transient request source.
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Execute the instruction again after lower the transient transmission usage
frequency.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
Execute the instruction again after correcting the header information at the
transient request source, and retry the operation.
