Item Displayed information
Error Frames Number of error frames received on the EtherCAT slave’s input and output ports
Range: 0 to 254
•
255 or more is displayed if 255 or more error frames were received.
•
When the diagnostic and statistical information is acquired twice or more, the in-
crease from the previous acquisition is displayed in parentheses on the right of the
number of error frames.
Example: When the number acquired at the previous acquisition was 6 and in-
creased 4: 10 (+4)
•
Failed is displayed when the number of error frames cannot be acquired from
EtherCAT slaves for reasons such as absence of the relevant EtherCAT slave.
•
You cannot acquire the slave diagnostic and statistical information when the diag-
nosis/statistics log of the CPU Unit is in progress. If you click the
Get Button, Auto
logging is displayed for the number of error frames. Note that if the result of the pre-
vious acquisition was Failed , Failed will be displayed again.
Precautions for Correct Use
When you display the slave diagnostic and statistical information, first open a Sysmac Studio
project where the network configuration agrees with the actual network. If the network configu-
ration in the project does not agree with the actual network, the slave diagnostic and statistical
information is not displayed correctly. If a project where the network configuration agrees with
the actual network is not available, create a new project, make the network configuration in the
project agree with the actual network, and then display the slave diagnostic and statistical infor-
mation. Refer to the
Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for informa-
tion on building the network configuration.
Diagnosis/Statistics Log of CPU Unit
The periodic auto-acquisition of the diagnostic and statistical information is allowed for the following
purposes during a test run or normal operation of equipment.
• Checking the EtherCAT network line quality for predictive monitoring and preventive maintenance
• Finding locations of errors when they occur
Version Information
• A CPU Unit with unit version 1.11 or later is required to use this function.

Overview
This function acquires the diagnostic and statistical information that the EtherCAT master and
slaves have. The information is acquired at the specified cycle and saved as a log file in an SD
Memory Card that is mounted on the CPU Unit.
Use system-defined variables to set the execution command for this function and the cycle at which
the diagnostic and statistical information is saved.
