15.1.4 Error and Warning Logs
FP7 MC Unit has log areas to store error and warning codes in its unit memories.
• Once an error/warning occurs, the error/warning code will be stored in the log area of the
axis that the error occurred.
• When an error/warning that is not related to the axes occurs, such as a failure in the unit, the
error/warning code will be stored in the log areas of all axes.
• In the data monitor or tool operation dialog box on CMI, only the latest error and warning
codes of each axis can be confirmed.
• For referring the error and warning logs for each axis, read the following unit memory from
the PLC.
