• Program example
(0) After the function block for continuous logging data transfer becomes in start status, the continuous logging is started.
(17) 'G_bReadFbEn' (M20) is turned on and the function block for continuous logging data transfer is started.
If data omission occurs during continuous logging because of the processing time of the other scan program or interrupt program, the function block turns
on 'G_bErrReadLogging' (F0), and this stops the read of logging data.
(297) After the transfer of the logging data for 100000 points is completed, the continuous logging and the function block for continuous logging data transfer are
stopped.
