3. More explanations for M1347,M1348, M1524, M1525, M1526, M1527:
Generally when pulse output is completed, PLSY instruction has to be reset so that the
instruction can start pulse output one more time. When M1347, M1348, M1524, M1525, M1526
and M1527 is enabled, the associated output terminals will be reset automatically when pulse
output is completed, i.e. the PLSY instruction is reset. When PLC scans PLSY instruction again,
the pulse output starts automatically. In addition, PLC scans the mentioned 6 flags after END
instruction, hence PLSY instruction in continuous pulse output mode requires a delay time of
one scan cycle for next pulse output operation.
The function is mainly used in subroutines or interrupts which require high speed pulse output.
