Troubleshooting using the Error Log
Section 7-5
7-5-2
Error Codes
The error codes are described in the following table. The detailed error code
will provide detailed information on an error.
Note
1.
The time information from the CPU Unit is used in the PROFIBUS-DP
Master Unit.
2.
An error record is not created in non-volatile memory when the error con-
cerns an Error Log Write error.

• Check the Master stations on
the network, and make sure they
are all working correctly.
• Check the HSA setting in CX-
Profibus, and make sure it is set
to the Master station with the
highest address on the network.

• Check the network wiring, and
make sure it is correct.
• Check for short-circuits.
• Check the bus timing set
through CX-Profibus.
• Check if any other faulty devices
are on the same network.
• Verify that the Highest Station
Address setting includes any
other Master Address on the
bus.
