4.12 Application Error Detection

With the application error detection function, applications using the custom API library are automatically detected from all
applications that are operated in the display unit of M800 Series, and the presence and absence of responses are observed
at fixed intervals. Applications which give no response and remain unchanged for a period of time are detected as abnormal
and the log is saved.
(*) This function is valid on Windows-based display of M800W/M80W Series only.
The application error detection function does not particularly display the error message etc. when an error is detected, but
it saves information and data log to investigate the cause easily. On the input/output screen, saved log can be transferred
to SD card.
If the screen operation is disabled due to an error such as screen lock, turn the NC power OFF, then turn it ON again, and
output the log files to an SD card on the input/output screen.

(*1) The timing to save the log.
A: When error is detected.
Observation application saves the log when the error has occurred.
B: Constant
It saves the given amount of log constantly.
It keeps saving logs even after the error detection, so presume the time when the error has occurred from the
time in the log.
C: When the error detection is started

Timing What you understand from
for saving the information
(*1)
A Application name in which the
error occurred.
C The elapsed time from when
the NC power is turned ON to
the error occurrence.
A By comparing with the time of
various data, it can search the
information on when the error
occurred.
A It can confirm the connection
state when the connection error
has occurred between PC and
NC.
B It can confirm the operation
when the error has occurred.
