A598 A59800 FPD Teach-
ing Bit
Turn this bit ON to set the monitoring
time automatically with the teaching
function.
While A59800 is ON, FPD(269) mea-
sures how long it takes for the diag-
nostic output to go ON after the
execution condition goes ON. If the
measured time exceeds the monitor-
ing time, the measured time is multi-
plied by 1.5 and that value is stored
as the new monitoring time.
(The teaching function can be used
only when a word address has been
specified for the monitoring time
operand.)
