• Interrupt program
(262) If both 'CH1 High speed continuous logging data A side storage flag' (Un\G476) and 'CH1 High speed continuous logging data B side storage flag'
(Un\G477) are on before the logging data transfer, 'G_bErrorDetectionBeforeSend' (M10) is turned on as an error. In such a case, the logging data
transfer is stopped.
(319) The logging data are transferred to the file registers. The 10000 point logging data sets are transferred per interrupt. The transfer is repeated until the data
are transferred to ZR99999. If data omission occurs during the read of high speed continuous logging because of the processing time of the other high-
priority interrupt program, the following devices are turned on.
'G_bErrorDetectionSideA' (M11)
'G_bErrorDetectionSideB' (M12)
(633) If data omission occurs, 'G_bErrorDetection' (F0) is turned on.
(639) When the transfer of 100000 point logging data sets (ZR0 to ZR99999) is completed, 'G_udWritePosition' (D20) is set to a value in
'G_udWriteStartPosition' (D10). After that, logging data is stored from ZR0 repeatedly.
(666) 'Interrupt factor detection flag [1]' (Un\G4) is turned off and 'Interrupt factor reset request [1]' (Un\G156) is turned on so that an interrupt functions properly
when an interrupt condition is satisfied next time.
