Action
• Check the connection of the SD memory
card. If the problem persists, there may be a
malfunction in the SD memory card or CPU
module.
• Format the SD memory card. If the problem
persists, there may be a malfunction in the
SD memory card or CPU module.
• Recreate the file.
• Rewrite the project.
• Rewrite the project.
• Modify the parameter set value and rewrite
the project.
• Modify the parameter set value and rewrite
the project.
• Modify the module parameter set value and
rewrite the project.
• Write the correct security key to the CPU
module.
• Write the security key to the CPU module.
• Rewrite the security key to the CPU module.
• Recheck the remote password parameter
setting or module configuration.
• Verify that the connected module is powered
on.
• Verify that extension cables are correctly
connected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module.
Replace the connected module.
• Avoid connecting a module during operation.
• Verify that extension cables are correctly
connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• If the version of the CPU module is correct,
there may be a malfunction in the connected
module. Replace the connected module.
