2
Check for errors in the trends shown in the master diagnostic and statistical information.
3
Find the locations of the errors with trends in the slave diagnostic and statistical information.
4
Implement corrections for the error locations that you found.
5
Confirm status after implementation of the correction.
Step 1: Acquiring Diagnostic and Statistical Information for Master and
Slaves
There are two methods to acquire the diagnostic and statistical information for the master and
slaves. The following table describes each method. Use either of the methods to acquire the diag-
nostic and statistical information for the master and slaves.
Acquisition method
Description
Reference
Using the diagnostic
and statistical informa-
tion display of Sysmac
Studio
Use the Sysmac Studio to acquire the diagnostic
and statistical information. You can save the ac-
quired diagnostic and statistical information in the
computer.
Refer to
Statistical Information Dis-
play of Sysmac Studio
Using the diagnosis/
statistics log of CPU
Unit
The CPU Unit acquires the diagnostic and statisti-
cal information periodically. The acquired diagnostic
and statistical information is saved in an SD Memo-
ry Card that is mounted on the CPU Unit.
Refer to
Precautions for Correct Use
When the Sysmac Studio’s diagnostic and statistical information display is used, the maximum
number of error frames recorded for the slave diagnostic and statistical information is 255. If the
number of error frames exceeds 255, increasing trends of the number of error frames cannot be
recognized. If the number of error frames for the slave diagnostic and statistical information is
assumed to exceed 255, execute the clear operation for the slave diagnostic and statistical in-
formation before acquiring the slave diagnostic and statistical information.
Step 2: Checking for Errors in Trends in Master Diagnostic and Statistical
Information
Check for trends in the items in the acquired master diagnostic and statistical information to diag-
nose errors in the EtherCAT network.
